How to cut a metal tile on the roof. Work carved scissors

Hand tool for cutting metal tiles

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.

Leading manufacturers prohibit cutting a metal grinder (corner grinder) and deprive the products using this tool when using this tool.

  • The corner grinder greatly heats the cut place, melts the protective zinc and polymer coating, deprives the roofing sheet of the ability to resist corrosion. it will rust up for several years;
  • When working, a corner grinder forms many uncontrolled sparks. 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 read in this article.

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.

Nozzle on the drill

The nozzle for cutting metal tiles converts the rotational movements of an electric screwdriver or drill into reciprocating, making it possible to cut metal.

  • small cost of the kit;
  • The cut rate is quite high (faster the angular grinder, 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.

Cutting metal grinders. for and against

Metal tile manufacturers officially forbidden to cut it with a corner grinder. Despite this, many private builders continue to use the tool that is common in the household. It’s a pity to spend money on something else, if there is already a more or less suitable device.

The corner grinder cuts the same way as a circular saw, quickly and easily. Why are professional builders and manufacturers of this roofing material so protest so against its use? And is it possible to cut a metal grinder?

  • The torn edges of the metal during further operation are oxidized and rust.
  • The metal is heated strongly, deformed and rusts at the ends.
  • Italian expensive tiles with a plastic coating is sold with a written guarantee for 15 years. If experts reveal the use of an angular grinder for its cutting, the guarantee is lost.
  • Corner grinding is dangerous to use on the roof.
  • When the metal grinder is cutting, a lot of small metal sawdust flies off, which over time rust and spoil the appearance of the roof.
  • You can burn stacked waterproofing and moisture will seep to the crate.

Those masters who do not want or cannot refuse to cut a corner grinder can advise a proven combined method. The metal tile is cut with a corner grinding, adding 1-2 cm to the desired size, and then the melted edge is cut into size using scissors for metal.

In this case, quality does not suffer, do not buy or rent another tool, but the complexity is doubled.

Alternative tools for cutting metal tiles

For cutting the metal tile, the sheet is laid on a flat horizontal surface. Under it in several places the bars of the same thickness are placed. A line with a chalk or felt.tip pen is applied along the line. When cutting, it is necessary to hold the sheet. To do this, put a wide board on it and move along it, cutting off and pressing at the same time. At the end of the work, trash and sawdust from the sheet should be removed. After cutting the place of chips, slices, the ends are processed by the repair enamel of polymer coatings to protect against corrosion.

A wonderful nozzle for a drill for cutting a metal tile with a beautiful name “cricket” easily copes with the diagonal cut of the sheets of the most complex texture. The nozzle with fasteners can be set the desired angle for ease of work. Such a tool is easy to cut steel sheets up to 0.8 mm thick. Compared to a circular saw and even a corner grinder, a drill with a nozzle will cost cheaper.

Fixing / Installing Lightweight Roofing: Tiling (Roma Profile)

In electric cut scissors, the principle of operation is the same. The rotating rod with winning attacks cuts the sheet not by the end, but the side surface. These tools are good because they can cut out the most complex configurations from a metal sheet.

All of these devices are good. But each of them is good in its own way. By comparing all the pros and cons, you can choose the most acceptable tool in this particular case.

Is it possible to cut a corner grinder with a diamond disk

Why is it impossible to cut roofing metal with a corner grinder? When working as a conventional abrasive disk, too much heating of the material occurs due to the occurrence of friction. This irreversibly damages the protective layer on the cut line and in the adjacent area. Thus it is impossible to cut off the metal tile.

Some builders believe that you can cut a certain special disk for cutting metal tiles. Or they advise using a diamond disk: they say, the cut is so fast that the material does not have time to heat up. The point in the question “Is it possible to cut a metal grinder?»Put the leading manufacturers of metal tiles.

In the use instructions for use, the use of corner grinders with any discs is unambiguously prohibited. Sheets warranty cut in this way is lost. It is unlikely that the authors of harmful advice will be taken over.

How to cut metal tiles with scissors for metal

Cutting metal scissors in their standard version is not available. This will require the following types of devices:

The latter equipment is facilitated by the task due to power from the network, which accelerates the process and makes it less time.consuming.

Preparation of the base

Installation of metal tiles. the final stage of roofing, forming the upper layer of the roof pie. The number and thickness of its other layers depends on whether the cold or heated room is located directly under the roof.

A separate article is devoted to the layout of the roofing pie, you can read about the differences in its device for a warm attic and a cold attic in it.

An important point of installation work is the preparation of the base. the crate for metal tiles. She has two functions. to be a supporting support for the MCH and level the pitched plane of the rafter system.

The height of the bars of the counterparty should be sufficient for the circulation of air between steel sheets and a waterproofing layer. Learn more about the ventilation of the roof of metal tiles

A rarefied crate is installed under the metal tile, it is made of dry homogeneous bars or boards. On the entire area of ​​the roof, their height should form a flat plane, without differences. The standard step between the battens of the crate is equal to the wave of metal tiles and is 35 cm.

Around the attic windows, chimneys, yends, the crate is made continuous.

The procedure for installing elements

Sheets of metal tiles and additional elements are installed on the crate in the following sequence:

  • cornice bar;
  • the lower elements of the yendova, the location of the pipes, walls, ventilation outputs;
  • sheets of metal tiles;
  • end strips;
  • the upper elements of the yendova and the location;
  • Skate bar.

Installation of cornice planks

Before installing the metal tile on the headboard of the cornice, a cornice bar is installed with an overlap one for another 5-10 cm. Its function is to protect wooden elements of the roof overhang from condensate and rain. This element is attached by galvanized nails with a distance between them about 30 cm. The edges of the waterproofing film are displayed on the crate and laid on top of the cornice of the bar.

After installing the cornice of the bar and the lower yends (more here), the consistent installation of sheets of metal tiles begins: from the pediment or from the apples. both options are permissible.

Methods of laying sheets

If installation is carried out from left to right, then the edge of each subsequent sheet of the MCH is laid under the previous. If roofing is carried out from right to left, then the edge of each second sheet is applied to the previous. The protrusion of the lower edge of the metal tile above the cornice is 4-5 cm.

An important point is to align the long sheets of metal tiles on the slope. It is carried out not relative to the pediment of the end, but relative to the horizontal line of the cornice.

It is recommended to put the sheet first, fixing in the skate bar with one screw. Then add another 2-3 sheets, fasten them with the first and together in one block at the seams with self.tapping screws, without fixing to the crate. Next, align the block relative to the cornice and only then fix the finally.

As a rule, the metal tile is supplied with chopped sheets along the length of the slope. If the length of the sheets is smaller, the installation of MCH on the roof is made in several rows.

The laying sequence looks as follows: two sheets in a row are fixed in a row, and the third is placed above the first in the second row. Further, all even sheets in the bill are 4, 6, 8 are laid in the first row, and the odd. 3, 5, 7. above them in the second row. The junction in length is carried out with an overlap of 10 cm.

If necessary, a sheet of metal can be cut off, they do it with a special tool. Read the article, the better to cut metal tiles.

The use of corner grinder is prohibited, strong heating melts and burns a protective coating and deprives the manufacturer’s guarantee. The cut places to avoid corrosion are treated with aerosol enamel for the repair of polymer coatings or painted.

Fasteners of sheets

The sheets are attached to the crate with roofing galvanized screws with a gasket from an EPDM response.

Self.tapping screws must be screwed perpendicular to the crate to avoid leaks and provide external aesthetics of the roof. They are screwed into the deflection of the MCH in a checkerboard pattern through one wave, the exception is the first lower row above the cornice of the bar, here the fasteners are screwed into each wave.

The dense fit of the sheets of the metal tile to the crate prevents its vibration and excessive noise. This is achieved due to the lack of changes in the heights of bars and the uniform arrangement of fasteners. 6–8 pieces per 1 sq. meter.

Installation of end planks

After the laying of sheets of metal tiles is completed on top of the pediment boards, an end bar is installed, which prevents falling under the coating of the side wind and precipitation.

Begin to mount the bar from below and continue up in the direction of the skate. They are attached with roofing self.tapping screws with a step of 1 m to the pediment and skate with a step of 30–80 cm in a wooden crate on top of the metal tile. For the tightness of the connection, the end strips are applied one on the other with an overlap 10 cm.

The latter set skating strips, upper glaks of yendovs and safety elements. Read how to correctly install snow holders on metal tiles.

Compliance with the installation sequence, recommendations for cutting and the rules for attaching metal tiles will ensure the durability of the roof and retain the manufacturer’s guarantee.

Than and how to cut a metal tile. an overview of the tools

Metal building materials are extremely convenient to use. They have high flexibility and plasticity, at the same time, differing in strength. Before cutting a metal tile, it is necessary to study the tools with which you can work the basic rules for cutting this coating.

Before starting work, you need to study the structure of a sheet of metal tile. It consists of several layers: central and two lateral. The main one is a thin sheet of cold.rolled steel. A layer of zinc is sprayed under high pressure. Depending on the type of metal tile. It can also be covered with various composites or polymer substances.

Often the question arises why it is impossible to cut a metal grinder with a corner grinder. This tool cannot work precisely due to the features of the structure of the metal panel. The working part of the corner grinder is an abrasive disk rotating at a very high temperature. Because of this, the temperature rises significantly through the ends. Abrasive particles damage not only the top coating of the tiles, but the inner panel. In addition, high temperatures melt zinc, which significantly reduces its resistance to aggressive external factors.

Therefore, the following types of tools can be distinguished that cannot work when cutting metal tiles:

  • Any abrasive circles;
  • Files or saws with spraying;
  • Hand files for metal cutting (not used for curly cuts).

The last tool needs to be highlighted especially. Often home masters when cutting small areas of metal tiles, simple metal saws are used. But because of the gear surface, they leave on the coating of the zabines, which, during further operation, become a focus of corrosion.

In addition, all of the listed devices somewhat deform building material, changing not only its structure, but also form. This is unacceptable when working on the roofs of a complex structure.

Steel disk

In theory, you can try to cut a metal grinder and a diamond disk, but will have to be more careful than when working with scissors.

  • You need to work at low speeds to minimize the appearance of sparks and heating the surface of the coating;
  • You need to close all the tiles around. To do this, you can use metal sheets or corrugated board. Otherwise, individual sparks flying from under the cutting surface will damage the structure of the roof;
  • It is necessary to put on protective glasses and clothes.

The location of the screws

According to recommendations from manufacturers to calculate the amount of fasteners, you can multiply the total roof area by seven. For the installation of premature planks, their total length should multiply by eight.

The rules for fixing the metal tile to each other and to the crate (see the diagram in the figure):

  • Fastening by the cornice. through the wave, retreating 60. 70 cm from the edge of the sheet;
  • From the end board. into every wave;
  • Fixation of sheets with each other is performed in the area of ​​vertical overlap on the downturn of the wave;
  • Along the skate. through the wave;
  • According to the slope. the screws are distributed evenly, through the wave and through a row.

All screws are screwed into the deflection of the wave, at the place of fit of the metal tile to the crate.

Installation and fastening of sheets on the roof

If there are yendovs in the roof design, the installation is first performed on a continuous crate of the lower bar. The output of ventilation pipes and heating chimneys is additionally laid by thermal insulation.

Cutting sheets is made according to the location scheme. To do this, you need an electric saw with a disk cutter, metal scissors.

In order to avoid temperature effects on the metal tile, it is impossible to do it with a tool with diamond or abrasive spraying it. This can lead to damage to the protective layer.

  • Fasteners of the cornice of the boat plank with an overlap 10 cm and a step of self-tapping screws 30 cm. It is necessary to protect the crate from moisture. Additionally, a mesh ventilation tape hanging under the dropper is mounted.
  • The installation of the first sheet is performed in a place where there are no bevels, sections and similar structural components.
  • The subsequent sheet should close the capillary groove.
  • The position of the roofing material relative to the cornice line is checked.
  • After laying 3-4 sheets and monitoring their position, you can proceed to the final fixation according to the compiled mounting scheme.
  • The overhang on the side of the cornice should be at least 50 mm. In the presence of a horizontal drain, the metal tile blocks its upper part by 1/3.
  • To mark the metal tiles for triangular slopes, it is recommended to use a special template. “Devil”. Four boards form a square using articulated joints. Thus, you can mark the sheets directly on the roof.

Having completed the installation of the main roofing material, it is necessary to start the installation of additional components.

How to cut a metal tile? How to cut a metal tile correctly?

Metal tiles are perhaps the most popular roofing material to date. Use it for lining the roofs of residential private houses, cottages, garages, industrial premises, etc. D. The sheets of metal tiles have standard, very convenient sizes, and therefore there are practically no waste during installation. However, sometimes it is still necessary to cut this material. For example, in order to close the pediments. This work should, of course, strictly adhering to a certain technology. First of all, the owners of the country house will need to choose the right tool for cutting metal tiles.

Metal tape made of steel by cold stamping is made. The thickness of the sheets used in the production can be 0.4-0.6 mm, therefore, in principle, cutting them is not particularly difficult. However, from above and below they are covered with zinc and polymer layers that provide protection against moisture. In the event that during installation, these coatings are damaged, the roof will subsequently begin to rust very quickly. That is why the answer to the question of how to cut a metal tile is so important.

For cutting this material, not every hand tool can be used. For example, a corner grinder for this purpose is completely unimportant. This equipment is very warmed up by the cut surface, as a result of which the polymer coating of sheets (and sometimes zinc) simply fades.

How to cut a metal tile: select a tool

How to cut this roofing material correctly? Manufacturers recommend using so tools for cutting metal tiles as:

disk saws with carbide teeth;

Next, we consider how each of these tools is used and what the advantages and disadvantages are different.

Nozzle on the drill

When choosing how to cut a metal tile, you can resort to a nozzle for a drill, which is an addition for a conventional drill.

The principle of operation is similar to cutting electricians. Punch cuts out a certain piece of material for each course of the tool.

To use the tool, it is necessary to have skills in working with building tools, otherwise difficulties may arise during cutting.

Hacksaw or electric jigsaw

The cheapest and most time.tested tool is a manual metal saw. Does not need special skills and is available in almost every house. But at the same time, the saw does not allow you to perform curly cutting, for this it is necessary to resort to improved tools.

The electric jigsaw makes no less high.quality strokes than cutting scissors, but this will need more time. Lobzik with special nozzles allows you to cut any profiled metal sheets.

metal, tile, roof, work, scissors

It is interesting to know that the first mechanical scissors for metal were designed to install ventilation ducts and systems. Over time, the tool has radically improved and is now used for roofing.

Electric scissors for metal

There are three types of electric scissors for metal.

  • Cutting. With this tool you can cut both profiled sheets: corrugated board and metal tiles, and cooked from several elements, for example, pipes or ventilation boxes. The principle of operation of the device is based on cutting a small piece of material for each punch. You can start operating on cutting scissors both from the edge and from the middle of the workpiece, however, in the latter case, it will be necessary to drill a hole for cutting.
  • Knife electric tires for cutting metal tiles. Their cutting element is two single.legged knives. One of them is mobile, the other motionless, between them and a metal sheet is laid. When working with such a tool, there is no waste at all. The disadvantages of these electromechanical leaf scissors are the inability to make steep turns, as well as cutting only with an open edge.
  • Slitteaner for cutting metal tiles.This tool will easily cope with non.ferrous and black sheet metal, various material coatings will not interfere with it. Thanks to the open.type cutting head, the slotted electric scissors produce accurate and neat cuts, while the material of the material does not occur. The plus of such a device is its convenience if the figure cutting is necessary. In this case, the processed sheet is not subjected to deformations. In addition, the formed chips do not get inside and it can easily be removed from the working area. Initially, slotted electromechanical scissors were designed to install ventilation systems, but then professional roofers began to use them when assembling metal coatings. It is worth noting that if your primary task is a high quality of cut, then slotted scissors are the best tool.

What is a drill for cutting metal

Another tool that can be worked is a nozzle for a drill for cutting a metal tile.It is an addition to the most ordinary electrical device of this type.

In fact, such a device is a punch and a matrix that start under a roof profiled sheet of metal.

Nozzle on an electric drill for metal tiles.

When the electric drill works, the Punch starts moving and cuts off the desired shape from above in the metal tile.

It must be said right away that for work with a similar tool, you will need a certain skill and dexterity.

Cut width, while 3.1mm. The nozzle can process metal with thickness:

The nozzle before work must be fixed in the drill cartridge, it leads its mechanism into effect. The device works in the same way as cutting down electromechanical scissors. At the same time, you can produce, both straightforward and figure cuts.

When choosing how to cut a metal tile, keep in mind that such a nozzle is suitable for cutting coating and for installing external ventilation elements of the roof.

With a competent selection of the drill drive speed, you will get excellent cut results. The tool will not crush the edge of the metal, and they will turn out sharp.
