Shears for cutting corrugated sheets

Shears for cutting profiled sheets are necessary for builders (assemblers), and for sellers and manufacturers. There are electric and manual models of metal shears on the market for cutting corrugated board, and it is important to understand their features and types. A separate hot topic is how to cut metal.

It is not very reasonable to use standard metal-cutting shears for cutting profiled sheet. They can destroy highly sensitive material and degrade its quality. The danger is:

• strong surface heating;
• the appearance of sparks when cutting;
• violation of the geometry of the cut and the curvature of its trajectory;
• melting the edges on the profiled sheet.

Even hand scissors for metal can be used for corrugated boarding in the household. - if the manufacturer specifically stipulates their suitability for solving this delicate task. The advantage is that such a tool is suitable for many other jobs as well. At the same time, the objective disadvantage is the complexity of the manipulations, their slow implementation. Manual technique is suitable only for a relatively small amount of work. But it costs less than a power tool.

Manual scissors allow you to cook even rather complex roofing parts. It is recommended to cut across the wave. Hand-held devices can also be used to correct incisions that have already been made.

The principle of operation is the same as that of the well-known hole punch. Nibblers can also be powered by electric motors. Such models are designed for making a large number of curly and atypical cuts on sheets. The basic operating principle is no different. True, in terms of productivity, the electric shears are several times ahead of the mechanical counterpart.

It is very important to distinguish between "left" and "right" scissors. Only after understanding this characteristic, it makes sense to evaluate the length of the cutting edges, a straight or chamfered cut, the features of the fixing mechanism, and so on. Electrified devices are rated by:

• electric power rating;
• frequency of movement;
• type of recharge (from the battery or directly from the network).

The power indicator is directly proportional to the achieved performance. It is obviously related to the frequency of movements. The battery allows you to work even in hard-to-reach places where there is no possibility of connecting to the mains. However, it makes the structure heavier and larger, which is no longer so pleasant.

When the task is only to cut a sheet without special precision, you can order the most simple model of scissors. But it is important to check the quality and accuracy of the sharpening. Beginners should avoid used tools; only trained specialists can perform their work with sufficient quality. It is not recommended to purchase very cheap versions, because they do not provide a high-quality cut. Of course, you should also pay attention to the reviews.

For large jobs, you must use niblers... For your information: they are also suitable for cutting metal tiles.The equipment of professional teams includes all types of tools. After all, it is not known in advance what orders and what volume of work are to be faced. Well-known brands are better than other devices.

To cut the profiled sheet with hand scissors, it is placed on stable platforms. The distance to the fulcrum should be greater than the blade travel. The first step is to make a trial cut and test its direction. The appearance of strong edge deformations is unacceptable. If no problems are identified, a finishing cut can be made.

Nibblers require the sheet to be held in weight. The channel for fastening the functional head of the tool is passed with a drill. When you press on the handle, the punch begins to move, which pierces the steel. Once the hole is formed, the working block moves along the cut. In any case, it is necessary to control the condition of the cutting parts; Dull blades very often leave painful injuries.

Curiously, the slower power shears are easier to control. They are used by not too experienced builders. However, professionals also put the power tool aside if they have to perform careful processing or form curly cuts.
