Is it possible to cut corrugated board with a grinder

Cutting metal tiles with nibbling shears

Nibblers are good for small volume cuts. In this case, the metal tile also heats up, but weakly. Scissors can cut in a straight, complex curve.

possible, corrugated, board, grinder

The dimensions of the device are small. Scissors are controlled by special handles. You can cut in a curve or at an angle as freely as in a straight line thanks to the die holder. It allows you to set your hand arbitrarily.

The nibbler does not chip or burr, the cut is very clean.

How to cut material with a drill bit

The drill bit for cutting metal tiles consists of a punch and a matrix. The attachment is placed under the sheet. When starting, the punch is displaced, as a result, in the direction of travel, a strip of the desired shape is obtained. The cut width is quite large. 3.1 mm.

The attachment can be used to cut the following materials:

  • stainless steel up to 0.8 mm thick;
  • galvanized steel, zinc, copper up to 1.5 mm thick;
  • aluminum up to 2 mm thick.

For cutting thicker sheets, a higher speed is required, and this should not be allowed when processing metal tiles.

The drill bit for cutting metal or profiled sheet is fixed on the chuck. The principle is the same as installing an electromechanical punching shear.

In addition to a saw or electric scissors, the “Cricket” drill attachment is also popular. This device allows you to cut straight and diagonally, regardless of the complexity of the texture. With the help of fasteners, the nozzle can be installed at different angles. “Cricket” is cheaper than a grinder or circular saw.

Using electric scissors

  • Cutting. a punch acts as a working body of the tool, that is, when cutting, part of the material is cut out. But in this way, you can get cutting of any configuration, and the sheet itself can be cut both from the edge and from the center. In the latter case, you must first drill a hole.
  • Knife. 2 blades cut metal. One of them is motionless, and the second moves in its plane. In this case, there is no waste during cutting, but only straight lines or cuts with a small angle of rotation can be made. Slicing is only possible from the edge.
  • Slotted. the cutting element is open, very sharp, which allows you to get a clean thin cut. Chips are generated, but in small quantities and only from the top, so they are easy to remove before stacking.

You can also take a circular saw or jigsaw for cutting. But at the same time it is necessary to perform work on a flat horizontal surface, fix the sheets.

Features of cutting metal tiles

The metal tile includes several layers:

  • base. steel sheet;
  • protective zinc layer. the thickness varies depending on the type of material;
  • passivating layers and primers. improve adhesion, protect against moisture ingress;
  • decorative coating. creates color, sometimes a pattern. Coating thickness fluctuates greatly.

The main strength component is metal, but the tool must be selected taking into account other factors. If the metal easily tolerates high heat, this cannot be said about other layers of the composition.

What tools can be used to cut metal tiles

Metal tiles are a popular roofing material. It is lightweight, very easy to install, strong and durable. It has a multi-layer structure, so drilling or cutting should be done according to some rules.

Tools for cutting metal tiles

The list of tools and devices is quite large.

  • The nibbler is electrically driven. They act as a separate device and as a nozzle.
  • Roofing scissors. mechanical. Used for the same job, but require physical effort. The advantage is a smooth, clean cut edge.
  • Circular Saw. Only use reverse angle carbide discs for roof tiles. In this case, cutting the metal does not require an increase in speed.
  • A hacksaw for metal or a jigsaw. both manual and electric. The second option simplifies matters. However, with the help of a hacksaw, only straight cuts can be made, complex cutting is impossible.
  • Circulation saw. mechanical, with an aluminum circle. Suitable for cutting metal tiles, as it involves cold cutting.

With any type of cutting, the integrity of the decorative coating is broken and the cut is unprotected. It is necessary to paint along the cutting line.

Why you can’t use a grinder

Cutting metal tiles with a grinder is strictly prohibited. This is due to the peculiarities of the tool. A very fast rotating disc acts as a cutting device. It allows you to cut through the toughest materials. In this case, due to friction, the temperature rises significantly in the cut section. The metal easily tolerates such an effect, and the passivating, polymer layers melt, deform and lose their properties.

These layers serve as protection. When damaged, the base metal is exposed. black steel, which is prone to corrosion. Rust appears on such a site after a couple of years.

Useful Tips

How and how to cut metal tiles determines the type of roofing material, the amount of work, the nature of the cut. The recommendations are as follows:

  • If you need to cut in a straight line, take a regular metal hacksaw or scissors.
  • If the contour must be curly, nibblers, punching shears, and an electric saw with a special attachment are recommended.
  • When installing metal tiles, it is necessary to calculate the material in such a way as to reduce the number of cuts to a minimum;

In any case, it is impossible to use an abrasive mechanism for cutting: the cut is uneven, it is difficult to process.

Corrosion protection of edges

No matter how “gentle” the tool for cutting the roofing sheeting, the violation of the protective layer is inevitable. To avoid oxidation of the metal (and, as a consequence, shorten the service life due to corrosion), a protective mastic should be applied to the cut or painted with a special composition “in color”. When inspecting structures made of corrugated board, in the future, you need to pay increased attention to problem areas and resume protection at the first symptoms of corrosion.

The better to cut corrugated board

The main risks when cutting corrugated board. high temperature and sparks, significantly limit the list of those devices with which you can carry out the operation without the risk of serious damage.

For obvious reasons, torches are rejected immediately. The use of electric saws with fine-toothed discs is possible for the reason that they operate at low speeds of rotation (metal does not melt, but transforms into sawdust), and sparks are not formed.

The second type of tool, the jigsaw, also does not lead to overheating at a low speed of forward and reverse movements. Its advantage is also that it is possible to perform not only rectilinear, but also more complex cut shapes (which is important, for example, for the execution of zones of abutment to pipes and other elements on the roof).

If there is no special tool (and the number of cuts is small), you can use an ordinary hand saw for metal or attachments for a drill (screwdriver). Other varieties include inexpensive manual and more expensive electric and nibbler for cutting corrugated board.

The structure of the profiled sheet

In order to figure out how to properly cut corrugated board, you need to have an idea of ​​its structure. The material is made from thin (in a fraction of a millimeter) sheet metal with a continuous polymer coating. Giving a certain waveform provides the necessary strength characteristics, and the protective and decorative layer ensures durability. eliminates the occurrence of corrosive processes.

With any cutting, of course, the integrity of the protection is violated, which requires subsequent processing with special paints and varnishes.

Why you shouldn’t cut corrugated board with a grinder?

Profiled sheeting is a versatile material that is excellent for various construction purposes: as load-bearing and enclosing (decorative) elements. A large number of standard sizes allows you to choose the optimal variety with the desired characteristics and minimize the loss of profiled sheets “cut off”. However, in some cases: with complex configurations (for example, on the roof), waste cannot be dispensed with.

Inexperienced specialists have a question: how to cut the corrugated board and is it possible to use one of the most common tools for these purposes. a grinder?

Decking and grinder

The grinder is a professional tool, one of the key features of which is a high rotation speed. During the cutting process, the contact area is very hot. In the case of corrugated board, this leads to certain structural changes in the thin metal layer (potential risk of deterioration in strength properties and surface shape).

The metal particles directly in contact with the grinder simply burn out, and together with them. the polymer coating at a distance of about 5 mm from the cut (there are foci of the so-called edge corrosion). When cutting with a grinder, a large number of sparks also arise, which, scattering, can violate the polymer protection even at a distance of tens of centimeters from the cutting line.

Some experts “allow” the work of a grinder on corrugated board in case the “standard” abrasive disc is replaced by a special cutting disc. with fine teeth. This approach reduces damage, but does not completely protect from them. Therefore, where possible, it is better to abandon the grinder in favor of a more “gentle” tool.

Features of using the grinder

Often it is required to cut off a small part from the sheet, so people, without hesitation, use a grinder, not understanding how it negatively affects the material. It is allowed to use this tool only if it is equipped with a special disc used for cutting metal.

Important! It is optimal to purchase special discs, called products for cutting profiled flooring, since they have a small thickness, and their teeth are made using carbide materials.

After the cutting of the profiled sheet is completed, by all means all the cuts are processed, which requires processing with special paints that prevent the corrosion process.

To shorten the work process, some people tend to cut several sheets at once using diamond-coated discs for this, but such work in most cases leads to serious metal disturbances.

The advantages of using a grinder include the speed of implementation of the process, but there are much more disadvantages:

  • the grinder is represented by an abrasive tool, therefore, with its help, you can easily damage the sheets, since during cutting, hot metal particles appear that fall on the polymer coating, so they burn through the material, which leads to a corrosion process;
  • after cutting, uneven edges of the material appear, so such shortcomings have to be eliminated, and this also takes time and effort;
  • during work, an unpleasant and strong noise appears, as well as an unpleasant odor, which negatively affects the mood of the employee himself and the people living nearby.

Thus, if a grinder is nevertheless chosen for work, then a special disc for cutting corrugated board is certainly purchased for it, otherwise the material can be easily and significantly damaged, therefore it cannot be used to create a roof covering.

Features of material cutting

It is allowed to cut corrugated board with different types of tools, but it is important to carry out this process in such a way that the integrity of the sheet is not violated, and even and attractive cuts are obtained.

Important! The profiled sheet is a thin product, therefore, careless cutting may damage it, and it is also covered on top with various protective layers formed from polymers or galvanized steel, therefore it is not allowed to use standard cutting methods for this material.

Cutting of corrugated board by high-temperature methods is also not used, but this is due to the fact that although the coating is resistant to temperature changes and has high strength, an excessively high temperature leads to its burnout, therefore, both the coating itself and the sheet are damaged.

Many people are interested in whether it is possible to cut corrugated board with a grinder. This tool is not suitable for the material, since the construction, equipped with an abrasive wheel, significantly spoils the coating, and after work, the corrosion process begins soon on the cuts.

Important! It is allowed to use the grinder only when using a special disc equipped with carbide teeth designed for cutting various metal products.

How to cut a profiled sheet. what kind of disc, is it possible to cut with a grinder, tools

Profiled decking is nothing more than sheets of metal coated with zinc and, in some cases, additionally painted with special compounds to protect against corrosion. Their feature is a special geometry of the plane in the form of alternating protrusions and U-shaped recesses with a width of 30 to 300 mm. Various depths. For the manufacture of corrugated board, steel with a thickness of 0.55 to 1.0 mm is used.

It is these characteristics that determine the cutting characteristics when preparing parts of the size you need. There are three options for cutting corrugated board:

  • Using a power tool
  • Manually
  • On machine equipment

Below we will consider each of the options separately with a description of how to cut corrugated board correctly, listing the pros and cons of each method known to the masters.

Corrosion protection of edges

Corrosion protection of the edges of the profiled sheets significantly extends their service life. This event is especially important after cutting sheets with a grinder or a hand-held circular saw.

Cutting corrugated metal roofing with an grinder

When working with a grinder, due to the increased friction rate of the disc on the sheet, the part of the coating. zinc or special paint. literally burns out from high temperature.

Bare metal remains open to the impact of negative physical and chemical factors and very quickly degrades (rusts). To protect it, you should use special paints and varnishes. Their consumption for covering the cut ends of the profiled sheet is minimal, it takes little time and is easily done manually.

Such a small cost of additional material and working time will extend the service life of the corrugated board much longer and will fully justify themselves. Professionals definitely do not advise neglecting such a seemingly trifle if you want the material to serve you for a long time.

Hand tool

Hand tools suitable for cutting corrugated board include:

  • Hacksaw for metal
  • Hand jigsaw

Here you need to make a reservation right away. working with a hand tool is practical only for very small volumes of operations performed.

Another case when a hand tool is needed is the creation of complex cutting geometry when finalizing individual lines after working with a power tool.

In general, working with a hand tool for cutting profiled sheets is very laborious, takes a lot of time and effort. This allows us to conclude that cutting corrugated board using a hand tool is ineffective and unprofitable.

Is it possible to cut corrugated board with a grinder?

The greatest harm to the protective coating of the corrugated board is caused by heating to a high temperature that occurs during the cutting process. Therefore, the use of gas-cutting equipment for these purposes is completely excluded. For the same reason, you cannot cut the corrugated board with a grinder.

The fact is that when cutting with a high-speed tool with abrasive wheels, the metal in the place of the cut simply burns out. Together with it, the protective coating burns out, and not only along the cut line, but on both sides of it. The width of the damaged area, as a rule, is 3-5 mm, which leads to the occurrence of the so-called edge corrosion.

In addition, sparks flying out from under the abrasive circle are dangerous. Due to the high temperature, they can damage the polymer coating at a distance of several tens of centimeters from the incision site.

Cutting the corrugated board with a grinder is possible only in one case. if, before cutting the corrugated board, the abrasive wheel is replaced with a cutting disc for corrugated board with fine teeth. However, even in this case, it is not recommended to use this tool, since such a measure will simply reduce the amount of damage, and not remove it at all.

Hand tool for cutting corrugated board

In most cases, power tools are used, because they are more convenient to operate and quicker to use. The following power tool can be used to cut the Chishminsky corrugated board:

  • Bulgarian
  • Jigsaw
  • Electric shears
  • Hand-held circular saw

Tool for cutting corrugated board

Is it possible to cut corrugated board with a grinder?

Bulgarian, this is the popular common name for hand-held angle grinders. The device is practical enough for cutting various metals, including profiled decking.

The basic rule that must be observed when cutting the corrugated board correctly is to apply the cutting wheel corresponding to the type of material being cut.

For grinders, depending on their size:

  • Small (circle diameter up to 135 mm)
  • Medium (circle diameter up to 175 mm)
  • Large (circle diameter up to 325 mm)

How to cut corrugated board with a grinder? It is necessary to select circles corresponding in diameter to the passport size of the tool. This is important for the convenience of work.

In addition, the choice of size depends on the depth of the depressions on the profiled sheet.

Working with a small grinder with deep grooves on the corrugated board, you will not be able to immediately cut the sheet in the places of the lower corners. for this you will have to turn the sheet over to the opposite side. Therefore, immediately choose a grinder on which you can install a circle of maximum diameter.

The second feature of cutting corrugated board with a grinder is that the sheet should be exposed on pads at some distance from the ground or the plane of the table on which you are cutting. Otherwise, the circle will “cling” to the ground and raise a cloud of dust or simply spoil your desktop or workbench.

Using a grinder for cutting corrugated board in the hands of an experienced worker allows you to cut parts of the desired geometric configuration, including along an arc with certain radii.

Quite an acceptable way of cutting profiled sheets. But, again. only if you use:

  • Professional tool
  • Choose the right canvas

Home-grade electric jigsaws, firstly, are not powerful enough to perform such operations. Secondly, there are practically no canvases for them, with the use of which you can cut sheets with a thickness of 0.75 mm.

It is quite possible to cut the C8 corrugated board with a professional-grade electric jigsaw, the technical characteristics of which are to the liking of buyers, but you will have certain inconveniences in your work. First, the sheet for cutting needs to be installed in an upright position, and this is not very convenient, so it will be necessary to support the already cut strips, for which you need one, or preferably two, assistants.

The conclusion and opinion of professionals with experience. a jigsaw is not the best option for choosing a tool.

Electric shears. shears for cutting corrugated board

It is quite convenient to use such scissors. they cut quickly and for metal with a thickness of even 1.0 mm, with a certain skill of the worker, they are quite suitable.

They also allow making cuts of various complex geometries, but. After working with electric shears, bending of the sheet occurs along the edge of the cut.

This will require you to perform additional operations at the end of the cut. the edges will need to be trimmed by hand using a mallet or hammer with wooden lining on the sheet so as not to damage the metal coating.

Hand-held circular saw

A hand-held circular saw, just like a grinder, is very convenient when cutting corrugated board, if you have chosen a model with a large diameter of the cutting wheel and used a special cutting wheel for working “on metal”.

All work can be done in one turn on of the tool.

At the same time, it is also possible to make cuts along an arc with a certain radius of curvature.

So, the better to cut corrugated board?

Summing up the use of one or another power tool for cutting profiled flooring, we can conclude that the grinder and hand-held circular saw should be recognized as the most optimal and convenient. Electric shears and jigsaws are more suitable for a small number of operations.

Power tools are used in any area of ​​construction. A special need for them arises when you build a unique fence from a professional sheet with your own hands. Especially if it is planned to decorate the fence with forging elements.

Uniqueness can lie in design. It is here that all possible types of fence design from a professional sheet are listed, as well as ways to decorate it. Beautiful corrugated fences are an opportunity to stand out, emphasizing your individuality.

How to cut corrugated board with a jigsaw?

If you can’t decide how to cut the corrugated board, then we advise you to choose a jigsaw if you, of course, do not have any other tools already purchased. As a rule, this is the best choice for those who decided to independently engage in the installation of roofing in the country or the construction of a fence from a profiled sheet. It is advisable that it has a laser guide.

This tool is the most versatile of what you can cut a profiled sheet without spending serious effort and the presence of special skills. In addition, it can be used for carpentry work, and in order to cut down a few dry branches in the garden.

In addition, the jigsaw is very easy to maintain and use. The speed of work is high, the probability of injury is minimal; if the file breaks, it can be easily replaced, and even a beginner can handle cutting. All these qualities make the jigsaw almost the ideal tool for this task.

Now let’s dwell directly on the technology of its use:

  • Before cutting the corrugated board with a jigsaw, draw a cut line. To do this, you can use a regular marker.
  • Secure the sheet so that it is at least 10 centimeters from the surface and does not move when cutting. For this, you can use ordinary goats.
  • Now you can start cutting directly. Don’t rely on the “eye”. use the laser pointer to keep the cutting line straight and precisely tailored to your needs.
  • Try to press the jigsaw tightly against the sheet where possible. This will reduce the risk of file breakage.
  • Despite the fact that this tool for cutting corrugated board is quite safe and has many mechanisms that protect a person from injury, be extremely careful. Hold the sheet by the edge, rather than rest your hand on it. over, do not keep your hand on the cutting line, even if the tool is still at a decent distance.

If you follow all these rules, you can easily cope with cutting corrugated board yourself. And you will do it quickly and without serious harm to cover the sheet.

Is it possible to cut corrugated board with a grinder?

The greatest harm to the protective coating of the corrugated board is caused by heating to a high temperature that occurs during the cutting process. Therefore, the use of gas-cutting equipment for these purposes is completely excluded. For the same reason, you cannot cut the corrugated board with a grinder.

The fact is that when cutting with a high-speed tool with abrasive wheels, the metal in the place of the cut simply burns out. Together with it, the protective coating burns out, and not only along the cut line, but on both sides of it. The width of the damaged area, as a rule, is 3-5 mm, which leads to the occurrence of the so-called edge corrosion.

In addition, sparks flying out from under the abrasive circle are dangerous. Due to the high temperature, they can damage the polymer coating at a distance of several tens of centimeters from the incision site.

Cutting the corrugated board with a grinder is possible only in one case. if, before cutting the corrugated board, the abrasive wheel is replaced with a cutting disc for corrugated board with fine teeth. However, even in this case, it is not recommended to use this tool, since such a measure will simply reduce the amount of damage, and not remove it at all.

How to cut corrugated board?

Decking has a lot of advantages, one of which is the ease of processing this material. Since the profiled sheet has a small thickness and light weight, it can be adjusted directly on the construction site. And for this you do not need to purchase a special machine for cutting corrugated board, a portable hand tool is quite enough.

But, despite the apparent simplicity, cutting corrugated board has its own characteristics. This is explained by the fact that, unlike conventional sheet metal, a profiled sheet is a layered cake made of a metal base and multilayer protective and decorative coatings.

The destruction of protective coatings when cutting corrugated board will inevitably lead to active corrosion and significantly reduce the service life of structures made of profiled sheet. Therefore, it is very important to know how to properly cut corrugated board in order to prevent significant damage to the zinc layer and protective paint.

How to cut a profiled sheet to maximize the preservation of the protective properties of its coating?

Many builders prefer to use an electric saw with a profiled sheet cutting disc. This tool has a number of advantages:

  • The rotational speed of a circular saw is almost 2 times less than that of an angle grinder, therefore, the metal of the profiled sheet does not melt under the action of the teeth of the disc for cutting corrugated board, but is removed in the form of small sawdust.
  • The ability to quickly cut a large number of sheets
  • You can buy a disc for cutting corrugated board in any building supermarket, in the same departments where abrasive cutting wheels are sold.

However, be very careful when using a power tool with a rotating wheel, as metal pieces formed during cutting can cause injury. Therefore, this tool requires certain skills to work with it and is not suitable for beginners.

If you need to cut a small number of sheets, then a classic tool for cutting corrugated sheets is perfect for you. a hand hacksaw for metal. It is extremely easy to use, allows you to make a cut of absolutely any shape and is safe even for a person with zero construction experience. Of course, it is also possible to get injured from using a hand saw. however, such an outcome is extremely unlikely compared to other tools.

But this method also has its drawbacks. The main one is the large amount of time needed to complete the work. In addition, you will need a special table for cutting corrugated board.

Another option is to use a hand or electric saw. With the help of them, the work will be done faster, however, with their help, you can cut corrugated board only in a straight line.

How I Make Straight Accurate Cuts With The Angle Grinder

Unlike the previous method, cutting the profiled sheet with a jigsaw allows you to make curved cuts of any shape. This adjustment is often necessary when installing roof coverings in the places of passage through the roof of ventilation and chimneys. However, before cutting the profiled sheet with a hand or electric jigsaw, you need to carefully mark the sheet so as not to be mistaken with the dimensions of the cutouts.

The disadvantage of this method is that cutting the corrugated board with a jigsaw is possible only with a profile height of no more than 20 mm. When cutting higher profiles, the blade tears metal and often breaks.

Finally, if you need to adjust the profiled sheets of small thickness, you can use the scissors to cut the corrugated board. It can be either ordinary manual shears for cutting sheet metal, or special electric shears for cutting profiled sheets.

Shears for corrugated board can be of three types. these are punching, knife and slotted. The most accurate cut is obtained if you use slotted shears for the profiled sheet. They are equipped with a special head that allows you to make an accurate cut without any deformations and distortions.

Electric shears are very popular among professional builders. They are considered one of the most convenient tools for cutting profiled sheets.

In addition to conventional manual and electric shears, nibblers are also used. They cut the profile sheet in two parallel straight lines, which avoids bending the sheet. Before cutting the corrugated board, using a special handle, the matrix holder can be turned at an angle of 90 ° to the cutting line. This allows you to cut a profile that is bent at right angles without burrs.

The only drawback of these tools is their high cost and, most importantly, an extremely narrow field of application. If cutting corrugated board is not your daily routine, then it makes no sense to buy nibbling or electric shears.

Many roofers use in their work such a tool for corrugated board as drill bits. If you have certain skills and use a cordless drill, such a nozzle is very convenient for cutting and adjusting the profiled sheet in hard-to-reach places.

As you can see, the choice of possible instruments is quite large, and each of the options is optimal for a certain situation and loses to analogs in another. Therefore, it is quite difficult to say unequivocally what is better to cut corrugated board without reference to a specific task. How to cut a profiled sheet in each individual case is decided by a specialist, taking into account the complexity of the shape of the cut, the ability to access it and his personal skills and preferences.

Corrosion protection of edges

Even the use of special tools for cutting corrugated board does not guarantee complete protection against damage to the covering of the corrugated board. Only in profiled sheets of galvanized steel of the 1st class of zinc coating thickness, the presence of molecules at the cut creates a barrier that prevents metal oxidation.

Therefore, in order to avoid shortening the service life of the corrugated board, it is imperative to apply a special anti-corrosion mastic to the cut edges. In addition, you can also paint these places with paint in the color of the protective coating of the profiled sheet. Fulfillment of these simple requirements will reliably protect the edges of the corrugated sheets at the fit points, ensuring the reliability of the profiled sheet throughout its entire service life.
