Why it is impossible to cut the metal tile with a grinder: why it is impossible to cut the metal tile with a grinder | Builder

For many, the name of this article sounds like something ridiculous, but everything is true in the name, metal tiles, corrugated board and any other galvanized sheet with a polymer coating is really prohibited from cutting.

So in the estimates, if we “open” the rate on the device of the roof of metal tiles, then the cutting circles will not be written off in the materials on the rate, and the Bulgarian will also be absent in the mechanisms and the composition of the work and work with it, accordingly, work with it.

Let’s still figure out why you can’t cut the metal tile with grinder?

When using the grinder, the cutter is carried out due to the friction of the cutting circle on the surface of the product, which leads to an increase in the temperature of the contact location of the processed material and circle. Respectively zinc and polyester or polymer coating at the site of the cut and along the edges of the cut is also destroyed. As a result, these places in the process of exposure to an external aggressive environment begin to rust.

I would like to note the same, that sparks that occur during the cutting of metal tiles, falling to the surface of the sheet, also burn its protective coating and in the future lead to darkening of these places, and after a couple of years, to the occurrence of rust.

Someone will say that it is enough to paint the place where the place where they cut it with a grinder and everything will be fine, but this is far from the case. The spray can does not restore the protective coating of the burned metal, but is only able to hide small defects in the form of scratches or scissors cutting places. I want to note that, for example, the cans are written off in and, just designed for painting places of cutting with scissors.

Someone, of course, will say that I cut a million times and everything is fine. Well, I don’t know what to answer, then lucky. Just There is a large list of regulatory documentation in construction, which makes it clear that it is forbidden to cut a metal drawing with grinder. And the regulatory documentation, I think, was also not an abus, uncle Vasya, who had drunk with a cigarette on a bench, and it took shape on the basis of great practice and construction experience. In addition, there is a large selection of electronics, with which it is possible to cut a metal tile, corrugated board or a metal sheet that will not burn the processed surface.

Features of cutting sheets

The basis of corrugated board is the thin-leaf steel with a thickness of 0.3-1.2 mm. So that the material is not covered with rust and served for a long time, it is covered on both sides with a thin layer of alloy with zinc content. For the decorative component there are layers of special primer and powder paint, which also extend the service life of paintings.

During the installation work, the corrugated board is subjected to cutting. As a result, the protective layers are destroyed. Therefore, the most gentle tool is selected for cutting, and the edges are treated with anti.Corrosion agents.

Corrosion’s edges from corrosion

There are special paints in spray cans, which are applied by spraying to the work surface. They are delivered on sale with the same color solutions as corrugated board. Another option is anti.Corrosion mastic. In any case, you need to familiarize yourself with the instructions to find out if you need and what primer before the finish should be applied to the damaged edge.

Tools for cutting metal tiles. How to cut

If we talk about the tools that can be used for cutting metal tiles, then their list will look as follows:

  • Curtain scissors. For cutting metal tiles, sedentary scissors for metal with an electric drive are well suitable. They can be both a separate tool and a nozzle for a standard drill.
  • Manual roofing scissors. Instead of electrical devices, you can use analogues with a manual drive. But you need to prepare in advance that a lot of effort will be required to work.
  • Disk electric saw. To cut a metal tile, you need a disc with carbide disks. Discs should have a small step and reverse angle.
  • Hand hacksaw for metal or electrician with a set of appropriate files. These tools are also quite suitable in order to cut sheets of metal tiles. When using a hacksaw, one restriction arises. It will be possible to cut the material only on straight lines, and curved cutting is not available. In addition, a good workbench will need to work with a hacksaw.
  • Manual circulation saw with aluminum circle for aluminum cutting. The saw with this circle is durable. One consumable is enough to process materials for a good dozen roofs. This tool uses a cold cut, so covering the sheets of metal tiles will remain intact.

All these tools allow you to cut the metal tile without much damage, but to maximize the preservation of the sheets after processing, it is worth painting in those places where the cut line passed. It is also advisable to lay the sheets with chopped areas under entire sheets, if there is such an opportunity.

However, no matter how qualitatively an independent pruning of the metal tile was performed, the optimal solution is to order the cutting of sheets to suitable dimensions from the manufacturer, which will give certain quality guarantees. In addition, in some cases it is possible to choose a metal tile so that it does not need to be cut at all.

These options should be considered before cutting a metal tile using one of the described tools. Still it is much easier for the manufacturer to work with his own products. If you manage to plan the roof so that the cutting of the sheets is not required, it will be even easier.

Cutting using cutting scissors

Curtain scissors are able to heat the metal, in addition, it is very convenient for them to produce curved cutting.

Due to the fact that the profile of the metal tile can have turns up to 90 degrees, it will be quite difficult to cut it with ordinary scissors for metal. This should be concluded that it is better to use cutting scissors.

This tool is able to heat the metal, in addition, it is very convenient for them to produce curved cutting.

Small.Sized tool has convenient handles for cutting. At the same time, he can easily go through all the turns, regardless of their bending.

It is worth noting that the maneuverability of carved scissors will mainly depend on the existing length of the matricester. The larger its length, the more convenient it will work with the tool. This element is able to rotate. With it, you can turn the handle perpendicular to the cut or along its. The angle of inclination of the handle can also be adjusted, in connection with which there is an opportunity to avoid stop into the profile, which is planned to be cut.

Such a tool does not form burrs, and work will take no more time for them than using an electric saw.

It is worth paying attention to the fact that before cutting a metal tile, it is important to consider that this must be done sequentially, from one sheet to the next. At the same time, do not forget to protect other sheets of tiles and additional elements from chips hit them.

Curtain electronics

The implementation of many curly and non.Standard cuts on the sheet of corrugated board is best done with sample electric wizards. Their principle of operation is similar to the above manual cutting scissors. The difference lies in the method of movement of the cutting part of the punch. Progressive movements are transmitted from the flywheel of the electric motor.

Work can be performed both on weight and on the fixed sheet. A hole is preliminarily formed for installing the cutting unit. Then the tool is installed and turned on.

When choosing, you need to pay attention to the following parameters:

The main advantage of the use of cutting electronics is high performance and neat cut.

How can you cut a metal tile?

Internet magazine about roof roof Roof materials metal tile than you can cut metal tiles?

Metal tile. A metal profiled sheet of small thickness made of cold.Rolled steel with a certain shape and size of the profile waves.

Due to the fact that this material weighs little (4.5. 6 kg 1 m2), many individual developers dare to lay the material on their own.

But in the work of inexperienced people, the difficulty is expected. Cutting the material on the necessary sizes.

  • Outwardly attractive and inexpensive coating for the home, with a long service life.
  • Lightness of laying makes it possible to do the work on your own.
  • Using metal tiles. The right solution with a low bearing capacity of the rafter system and a weak foundation.
  • Due to the variety of shapes and colors, makes it possible to realize many ideas of designers.
  • Laying can be done in any season of the year, the metal tile is not afraid of sudden changes in temperature and high humidity.
  • Smooth surface of the material allows you to slide the snow without delay and drain rain water.
  • The roofing easily withstands ultraviolet radiation, high temperatures and sufficiently endured to mechanical damage.
  • Long life-reaches 50 years, take into account that about 15-20 years there is no need to make any repair of the coating.
  • The sheets of the material are easy to replace, and if you need a small repair, then they can simply be tinted.

Often inexperienced people are cutting metal tiles “grinder”, thus it is easily produced, but this method has a negative side.Any installation instructions necessarily say what is permissible to cut this material, and cutting using an abrasive disk is strictly prohibited. In addition, in the case of such cutting of a metal tile, the warranty on the material is canceled.

metal, tile, grinder, only, recommended

The reason is that in such areas where the Bulgarian changed the characteristics of the protective layer, after 1 to 2 years it will begin to collapse from premature corrosion.

The internally structure of all varieties of metal tiles is almost the same. A layer pie, with a metal sheet located in it. On top and from the bottom, such a layer pie is protected by paint or layer of polymer.

If a diamond disk is used for cutting the material, then it significantly increases the temperature of the steel layer during operation, as a result of which the characteristics of the metal change, and a zinc protective layer burns near the cut.

But the most serious changes occur in the polymer layer. The materials used in the manufacture of a polymer layer for metal tiles are not able to withstand such high temperatures.

In addition, sparks from the abrasive disk cause damage to the coating in those places where they fall. This becomes the reason for the appearance of corrosion foci, which subsequently grow on a significant area.

It is advisable to use a simple metal tool for cutting, they are suitable:

  • Curtain electronics or simple metal scissors.
  • Disk saw with hard alloys.
  • Electric.
  • Kryazuvka for metal.
  • Circular saw. Circular.

Attention: metal tile is made of metal with a complex profile, for this reason it is quite difficult to cut it with scissors on metal.

The optimal way is to order cutting for the necessary parts according to the exact drawings from the manufacturer of the metal tile or to purchase a material of such sizes that it is not required to cut it during styling.

If there is no such possibility, then the sample electrician are well suited for this work.

They are in the form of a special device for electric drill or can be made as a separate tool. A good option is manual roofing scissors. You can use a disk power plant for cutting, with a carbide disk.

You can cut the material using a disk, fixed in aluminum, fixed in a manual circular saw. Circular, such discs serve for a very long time, one will be enough to lay 10 roofs. In addition, cutting is cold, polymer coating as a result does not burn out.

Convenient for home production an electric jigsaw. A jigsaw can be made of complex geometric rifles in any direction.

Attention! Whatever you use for cutting metal tiles, be sure to paint over the edge of the unprotected roofing with a cutter.

Tools necessary for cutting metal tiles

Cutting with cutting scissors

Curtain scissors are very small in size, their peculiarity is the matrices and 2 comfortable handles. It is important that you can cut with such a tool almost at a speed as a grinder.

The matrixing is easily rotated, which allows you to perform the most complex cuts of the sheet. Another positive property of electronics. They do not leave on the edges of the burrs. Therefore, after you will not have to additionally process the edges of the sheets.

Produce 3 varieties of electricity for metal:

    Slitting scissors. Such a tool will easily cut both black and non.Ferrous metal, they will not become an obstacle and any protective coatings of the material.A special cutting head makes it possible for the instrument to make neat and very accurate cuts, without distortions of the material. What is still good such a device. If necessary, it is convenient to perform elements of curly cutting.

The processed material during operation is not subjected to structural changes and deformations. It must be mentioned that if, first of all, the quality and evenness of the cut is important to you, then this is the most suitable tool for such work.

Cutting with a drill with nozzle

Drill with a nozzle called “cricket”. The nozzle of a special design for an electric drill. Consists of a matrix and a punch, during operation the matrix starts under a sheet of the cut material, and the working drill, moves the punch downward, breaking through a strip of the required shape in the workpiece.

Can diamond discs cut metal? All you need to know!

Nowadays and today, structures and buildings are often built from concrete and other solid metals.

You can’t just take an ordinary old saw.

Solid materials must be cut even more rigid and durable.

Diamond, if you still do not know, is The hardest substance of natural origin, known to man. Therefore, it is used for cutting solid materials, such as tiles, steel and concrete.

On the hardness scale of minerals, the diamond comes first, has a rating of 10 on the firmness scale of Moos.

But diamonds are also quite rare, which makes them quite expensive.

So, when you buy a diamond disk, it is actually a synthetic (artificial) diamond.

Without synthetic diamond, the cutting of solid materials would be almost impossible.

These blades also have many advantages compared to other metal and abrasive blades.

Yes, some diamond discs can cut metal. But it completely depends on the use of blades.

Most diamond discs are used to cut concrete, brick, tiles and asphalt.

Different blades mean different applications.

Each blade has its own style, shape and grooves. Which are important for its cutting ability.

Typically, each blade is designed for cutting a certain material or hardness of materials.

How to Cut Concrete with a Angle Grinder

Take, for example, the difference between diamond discs for concrete and asphalt.

Some blades are universal and can be used to cut almost all materials.

Before buying any blade, always be sure to examine and find out what its application is.

Check the packaging of the product. If you are not sure, ask someone to help in determining the application / specialization.

Steel is one of the most durable metals on the planet.

As for the diamond discs, some of them can cut steel.

Some canvases such as Husqvarna High Pro 3 and 5 episodes, suitable for cutting steel rods.

But in general, abrasive saws make a bet on the cutting of steel, not diamonds.

Abrasive saws are made of aluminum oxide grain inches reinforced with two sheets of fiberglass or other insulating material “, which is better for grinding steel.

You will not believe, but diamond discs not really cut.

Instead, they use the friction force to “grind” the material.

“Hard materials are best cut when the connection of the diamond disk is softer. As the diamond particles are blown up and destroyed, the ligament is released, so that most of the synthetic diamond can be subjected to material ”when grinding the material.”.

“The opposite is true for cutting milder materials. The connection is more durable to guarantee that the diamond is exposed for a long time for full use. “.

In fact, the blades scratch particles of each material.

The size of the blade will also affect what you cut, and on the project you are working on.

You will not go to the kitchen to cut the tiles with a 30-inch diamond disk and a massive detachment saw. You will probably use a much smaller electric saw with a more suitable 4-inch blade.

Keep this in mind when the next time you start a house repair project.

The size you have chosen will depend on the size suitable for your saw.

To find out, Read the management of the manufacturer of the saw or packaging of the product and find out what diameter of the blade is required.

The material that you cut and its use will be the most important factors that determine the expected service life of your blades.

However, it is well known that the diamond disk can be used about 100 times longer than the discs of other abrasive types.

The quality of the blade also plays an important role.

  • Low quality blades will last about 10 hours of the total cutting time.
  • Higher quality blades A have a service life up to 120 hours or even more cutting time.

Remember that cheap purchases in the long run are often more expensive.

Saws rotate at a speed of several thousand revolutions per minute (rpm). Add to this the fact that the blade is made of the hardest material on Earth, and you will get a rather serious cutting machine.

You do not want your hand or some other part of the body to be next to this blade.

Here are some tips that will help you protect yourself:

Put on the right protective equipment

When cutting a circular saw, road saw or something else with a high-speed blade Garbage will fly everywhere.

This means that you need to wear equipment that protects you, especially the face:

  • Protective glasses
  • Helmet (with a front mask)
  • Gloves
  • Long clothes
  • Respiratory equipment
  • Steel sock boots

Follow the manufacturer’s instructions

Just like a car needs a certain gasoline, saw and canvases have their own instructions that need to be observed.

Always check the manufacturer’s management, as well as the packaging of the product for proper safety and handling the product.

Do not force

With each use of a saw Forcibly use a saw is a bad idea. Don’t press too much.

Even diamond discs have their limits: they crack, coat and break.

Straight section

Simply put, do not cut the disk at such an angle that the sides of the saw are cutting.

The blades are designed for cutting only the edges of the saw, not flat sides.

How to cut metal tiles with electric scissors for metal correctly

There are three types of electric scissors suitable for cutting metal sheets:

  • Cutting. This type of scissors allows you to work not only with profiled metal, but with prefabricated structures like ventilation boxes or pipes. The working element of cutting scissors is a punch, which at every step cuts part of the material. Such scissors allow you to cut leaf metal both from the edge and from the middle of the workpiece, but in the latter case you will first have to drill the hole in it.
  • Khockless. The cutting details in this case are two knives with single blades. One knife is installed motionless, while the second has freedom of movement in one plane. For cutting, it is necessary to install a sheet of metal tiles in the space between two knives. The main advantage of knife.Type tools is the complete absence of waste during cutting. Disadvantages: firstly, the lack of the possibility of cutting with large angles of turns, and secondly, the possibility of cutting only from the edge of the workpiece.
  • Shlitz. Swling type scissors are suitable for cutting any metals without risk of damage to the coating. The open cutting element of such scissors allows you to cut the tiles very accurately and neatly. When processing, the material is not deformed, which is a very important point when working with metal tiles. Swling scissors allow you to cut metal sheets along any given path, and the chips appearing during cutting remain on the surface of the sheet, so it is very easy to remove.

Initially, scissors with an electric drive were developed for the installation and repair of ventilation systems. After some time, specialists working in other sectors. Including roofers, paid attention to them.

metal, tile, grinder, only, recommended

For a fairly long period of time, a lot of experiments were conducted aimed at improving the technology of cutting metal tiles, as a result of which most masters preferred scissors with scalp. It is worth considering. After all, knowledge of what the specialists cut the metal tiles can be very useful in the independent choice of the tool.

If you have to cut profiled sheets, forget about the grinder. “What then to work?”. You ask. And I will answer you!

One. The most suitable tool for cutting tiles can be called a hacksaw for metal. With its help, the edge of the material remains even, burrs, hillocks or holes are not formed on it. Another thing is when you need to make a curved cut. In this case, another tool will be required.

A jigsaw will come to the rescue, while any: both electric and ordinary manual. Yes, you will cut it much longer, but save the protective layer of profiled sheets. Due to this, their life will remain long.

If you do not matter, the edges of the metal will turn out even or wavy, you can use the electric scissors. They are very easy to work, special knowledge and skills are not required for this.

It is best to cut profiled sheets with slotted type scissors, they are universal, leave the smooth edge of the metal and do not deform it.

Curtain electric scissors will help make two parallel straight lines, you will not have to bend the sheet for this. With figured cutting of profiled sheets, it is recommended to choose this particular type of scissors.

And you knew that profiled sheets can be cut a drill? To do this, use special nozzles. The only moment is not so easy to work with a drill, the first time it may not work.

How to cut a metal tile so as not to damage the material?

On a simple form, the installation of a metal tile is not difficult and is carried out quickly enough. When complicated by roof shapes, as well as in the places of adjacence to pipes and lendov, there is a need for cutting sheets. It is difficult and tiring to do this with an ordinary tool, since the steel sheet is profiled. It has a figured relief. Let’s figure out how to cut a metal tile without damaging the protective coating.

Why you can’t cut the metal tile with a grinder

Leading Manufacturers prohibit cutting metal tiles with a grinder (Ushm) and deprive the guarantee for products when using this tool.

  • The grinder greatly heats the cut place, melts the protective zinc and polymer coating, deprives the roofing sheet of the ability to withstand corrosion. It will rust up for several years;
  • During the operation of the Ushm, many uncontrolled sparks are formed. Scattering the rain, they burn a polymer coating. These foci of corrosion in a short time can destroy the sheet.

Visic and polymer coating invisible to the eye can reduce the life of the roof service. How to choose high.Quality metal tiles, see the link.

Review of tools

On the market there is a wide variety of modern tools that allow you to cut a metal tile with the least efforts, with sufficient speed and without damage to the material:

After analyzing the pros and cons of these devices, you can choose a tool that is most suitable for each specific case.

Metal hand scissors

One of the simplest and most inexpensive manual tools for cutting sheet metal, the use of which is justified with small volumes of work.

  • This is the cheapest option of all presented;
  • There may be various modifications. For direct, right or left cut, combined;
  • They reserve a smooth edge without damage;
  • Easy to use. The principle of operation like ordinary household scissors.

The disadvantages of hand scissors for metal are as follows:

  • Cutting requires great efforts;
  • With large volumes, it is impossible to use them;
  • Having swollen, they can bend the metal, especially in the places where the wave lifts, get stuck in it, slowing down the workflow.

Curtain scissors

Manual cutting scissors are designed to cut round openings for the outputs of pipes or V-shaped samples inside a sheet of metal tiles inside.

  • Used to cut inside the sheet and can be used for flat and profiled sheets;
  • Comfortable rotary pen;
  • Do not bend metal, do not make burrs. They leave behind them a smooth and neat edge.
  • Small performance;
  • The need to use significant physical efforts during work;
  • A fairly high price for a hand tool.

Circular Saw

This is a universal power tool in demand in everyday life. They can cut wood, metal, plastic. The disc saw has sufficient power and good performance. This is its main advantage. For cutting metal tiles, it is necessary to use a disk with teeth, not an abrasive.

  • Easily and quickly performs straightforward cuts;
  • Applicable for large volumes of work;
  • The tool due to the removable disk is used to cut different materials;
  • Modern models work from the battery. A convenient option when working on a roof;
  • Buying a disk for cutting metal will cost cheaper than a special power tool for metal tiles. For example, cutting scissors.
  • Cannot perform curved cuts;
  • The tool is traumatic, especially when working on the roof;
  • It is difficult to work on top;
  • With improper tuning and using an inappropriate disk, the circular can tear the metal, exfoliate the protective polymer coating.

Curtain electronics

Their other name is cut. The principle of their action is a quick consistent carriage (cutting down with a punch and matrix) a track of 5 mm wide. This is a fairly powerful power tool that has the following advantages:

  • The high cut rate in any direction, and you can start a cut from both the edge and in the center of the sheet, having previously drilled the hole for the entrance;
  • The ability to produce curved cutouts;
  • The tool reserves the edge even without damage, without jamming and bent;
  • It is convenient to work with carriers with one hand in any conditions, including at a height.
  • High price, especially if you take into account the specificity of the use of this tool;
  • A large amount of shavings, sometimes it clogs into the tool.

You can choose and buy carriage scissors in the 220 volt store.

Nozzle on the drill

The nozzle for cutting the metal tile transforms the rotational movements of the screwdriver or drill into the reciprocating, making it possible to cut metal.

  • Small cost of the kit;
  • The cut rate is quite high (faster than the ear, but slower than the cutting electronics);
  • The nozzle can be used with a battery tool, which facilitates the work on the height;
  • A even neat seam forms without deformation of the metal tile (its thickness 4 mm) is formed.
  • You need to work with it with two hands and do it on the roof is somewhat problematic;
  • A large number of metal Serpics cut by the nozzle may represent the problem;
  • It is not very convenient to cut out the relief of the waves. The location of the drill can block the passage of the cutting part of the nozzle.

Each of the presented tools copes well with the sharp sheets of metal tiles, without damaging the coating and without depriving the buyer of the manufacturer’s guarantee.

Bulgarian: Recommendations “Metal Profile

Specialists “Metal Profile” are categorical: Cutting metal and profiled sheet is prohibited by a grinder.

Why you can’t cut metal tiles and corrugated board with a grinder?

First of all, The grinder cuts metal due to friction. The disk rotates very quickly, steel literally melts. Polymer and zinc coatings at the site of the cut will be burnt, which means that steel will be left without protection and quickly rust.

Secondly, During cutting metal or profiled sheet, sparks fly around the side. And this applies not only to the place of cut. Sparks fly apart more than half a meter. They fall on a polymer coating, burn it and zinc. Rust may appear in these places.

Thirdly, If you cut a professionalist or metal tile with a grinder, a guarantee ceases to operate on the roofing material.

That is why the “metal profile” does not recommend using the grinder when cutting metal tiles and corrugated board.

  • If you work with a grinder right on the roof, then you risk burning waterproofing. The roof will become leaky.
  • If the disk is jammed, it will fly to pieces. Shards can fall into your face.
  • If the grinder jumps out of the hands and flies to the side, the disk will continue to rotate by inertia. Such a “car” will cut everything in its path. Hands, legs and other parts of the body will not be a hindrance.

How to cut

It is best to cut small metal panels with scissors. Please note that experts recommend choosing options with long handles. They allow you to create quite large pressure without much effort. The tool should be strictly at right angles with respect to the chopped panel. The evenness of the cut depends on perpendicularity.

Tiles cutting grinder machine.

Light pressure on the intended trajectory is cut. When turning, you need to gently twist the edge of the metal sheet and turn the tool. Contrary to popular belief, the work of this device does not take time than cutting a saw, but, at the same time, is better from a technological point of view.

Cut with a saw or jigsaw you need to. First, the surface of the cut is marked. For this, you can use both chalk and simple pencils. If the metal tile is cut in a straight line, then there is no need to install it on a workbench, but when working diagonally or curved trajectory, it is recommended to fix the tool. You need to cut at low speed, monitoring the appearance of sparks.

The principle of cutting

You can even cut a metal tile. As you know, this is a multifunctional construction tool. Its mono use as a mixer, screwdriver and even as a saw for cutting panels. For this you need a nozzle for a drill. It is a small saw, which, using a special matrix, is capable of making cuts of any shape and size. Please note that for working with this tool you will need some skills. The incision can also be carried out along, across and diagonally. It is recommended to mark the surface in advance.

The ends of the metal tiles must be closed using outer paint. The enamel will protect the surface of the metal from aggressive factors and prevent corrosion;

If possible, it is recommended to fix the working tool;

Follow the condition of the cutting part. If it appeared on it, Zazubrins or chips, then the tool needs to be changed.

How to cut a metal tile

The question of how to cut a metal tile for an inexperienced amateur builder is quite acute. It is not very convenient to do this with ordinary tools, due to the fact that the metal sheets of this material are not smooth, but wavy.

Therefore, an electrician, in the absence of a skill, often breaks the files and tears the tiles, and when working with ordinary hand scissors for metal you will regret it after a couple of hours that you selected this material for the roof of metal tiles with your own hands.

Why can not cut the metal tile with a grinder

Therefore, cutting metal tiles is often carried out by a “grinder”. An electromechanical angle grinding machine with an installed abrasive disk.

It passes easily, sheets profiles and quickly copes with its work. However, this solution to the problem has a significant negative side.

All manufacturing companies in their installation instructions be mentioned than cutting metal tiles.

At the same time, it is said that its cutting with an angle grinding machine using an abrasive disk is strictly prohibited.

Over, the warranty on the material in this case is canceled automatically.

The fact is that such a roof covering with a metal tile a year or two will begin to flow from premature rust in those areas where the Bulgarian destroyed the protective coating.

The structure of all types of metal tiles does not fundamentally differ and is a layer pie. In its middle there is a thin sheet made of steel with a protective coating of zinc.

Layers of polymer and paint are applied to the tiles, on the back of the side it is also painted.

metal, tile, grinder, only, recommended

If an abrasive disk is used for cutting metal tiles, then its temperature increases significantly, the properties of steel itself change, and the zinc coating melts and melts.

But, the most significant damage unders the layer of a protective polymer. Plastisol, polyester, purl used for this do not have resistance to such high temperatures.

When working as an abrasive disk, the roofing material receives defects not only on the section of the section, but also where the sparks fly.

This leads to the formation of primary corrosion foci, which then apply to significant parts of the coating. The result is premature destruction of the roof of metal tiles.

Now that we negatively answered the question of whether it is possible to cut the metal tile with a grinder, we will find out what, after all, it should be done.

So how can it be cut?

Note! The ideal option is to order the entire cut from the manufacturer of the material, according to the exact drawings of the roof. The second optimal solution is to choose such sizes of tiles so that it does not have to cut it.

For cutting metal tiles, you can use an electrolobian

Когда подобной возможности нет, то можно использовать высечные электрические ножницы для листового металла. It can be, both of a separate tool, and is executed in the form of a nozzle on an ordinary drill.

How To Cut Tile With An Angle Grinder

Whatever tool for cutting the metal tiles you use, be sure to tint with facade paint, the left edge of the material without protection or put them so that they go under the upper sheets of the coating.

Why you can not use a grinder for cutting

The fitting of metal tile sheets is often performed using a grinder, despite the strict ban on its application for these purposes. Of course, in favor of this tool there are quite important arguments: firstly, the grinder very easily cuts the metal, and secondly, the work in this case goes very quickly. But these arguments completely lose their meaning as soon as it comes to the reasons why it is impossible to cut the metal tile with a grinder. In the documentation applied to the sheets of metal tiles, there is always a point regarding the cutting of the material. In this paragraph, among other things, it is always stipulated that cutting metal tiles with a grinder is strictly prohibited. Of course, this does not stop inexperienced masters, despite the fact that after such a cut, the guarantee for the acquired material will cease to act. The whole thing is the special design of sheets of metal tiles. This material upon closer examination is not just a homogeneous metal, but a multilayer pie, which includes a metal sheet with zinc coating, a layer of paint and polymer protection. If you cut the metal tile with a grinder, then the material will be excessively warmed up, as a result of which irreparable damage will be caused to each component of the pie. Most of all, because of this, polymers inflicted on the material, which are not designed for such high temperatures, suffer-they simply melt and in the future cannot perform their functions. In addition, polymers are damaged not only with direct exposure to the abrasive disk, but even from the hitting sparks flying in all directions. As a result of such a cut, metal also gets. The destroyed protective layer exposes the metal layer, which subsequently begins to actively oxidize. Even with a small area of ​​damaged areas, the metal is still corrosion. And after a couple of years such a coating will begin to flow, and after a few more years the material will have to be completely overcry. In general, you must definitely think about it before cutting off the metal tile with a grinder.

If we talk about the tools that can be used for cutting metal tiles, then their list will look as follows:

  • Curtain scissors. For cutting metal tiles, sedentary scissors for metal with an electric drive are well suitable. They can be both a separate tool and a nozzle for a standard drill.
  • Manual roofing scissors. Instead of electrical devices, you can use analogues with a manual drive. But you need to prepare in advance that a lot of effort will be required to work.
  • Disk electric saw. To cut a metal tile, you need a disc with carbide disks. Discs should have a small step and reverse angle.
  • Hand hacksaw for metal or electrician with a set of appropriate files. These tools are also quite suitable in order to cut sheets of metal tiles. When using a hacksaw, one restriction arises. It will be possible to cut the material only on straight lines, and curved cutting is not available. In addition, a good workbench will need to work with a hacksaw.
  • Manual circulation saw with aluminum circle for aluminum cutting. The saw with this circle is durable. One consumable is enough to process materials for a good dozen roofs. This tool uses a cold cut, so covering the sheets of metal tiles will remain intact.

All these tools allow you to cut the metal tile without much damage, but to maximize the preservation of the sheets after processing, it is worth painting in those places where the cut line passed. It is also advisable to lay the sheets with chopped areas under entire sheets, if there is such an opportunity. However, no matter how qualitatively an independent pruning of the metal tile was performed, the optimal solution is to order the cutting of sheets to suitable dimensions from the manufacturer, which will give certain quality guarantees. In addition, in some cases it is possible to choose a metal tile so that it does not need to be cut at all. These options should be considered before cutting a metal tile using one of the described tools. Still it is much easier for the manufacturer to work with his own products. If you manage to plan the roof so that the cutting of the sheets is not required, it will be even easier.

Is it possible to cut a drill with a special nozzle

Special nozzles for the drill for cutting metal tiles have the same sedimentary or slotted head as a specialized tool. The use of them does not damage the roofing material.

However, the performance of such devices and the convenience of working with them is significantly lower. The nozzles are reasonable to use with small volumes of cutting, when the acquisition of expensive special scissors is not justified.

Briefly about the main thing

For cutting metal profiled sheets, the use of a grinder is unacceptable. Its use removes products from warranty service.

A hand saw or mechanical scissors allow you to process a small number of sheets, since the installer should make physical efforts to bring the tool into action.

An electric tool can work from a network or batteries. The second option is especially relevant for working on the roof.

The most budget type of instrument is the nozzle for a drill or a screwdriver. Productivity is at an average level between manual and automatic equipment.

For direct cutting, any device is suitable, for a curve only part of the scissors, an electrician, nozzle.
