Assembly and manufacture of metal structures can be carried out using various types of high-quality metal products. The most widespread and demanded is a steel corner having the shape of an L-shaped profile, for more details see http://metpromplus.kz/catalog/ugolok.html . Industrial production is carried out using carbon steel.
Hot rolling
Hot rolling technology is one of the most common and effective methods. It includes the following loops:
- A workpiece made of carbon steel or structural steel is preheated to a ductile state.
- The workpiece receives a given L-shape of the required dimensions after processing by pressing with special rolls of a rolling mill.
This method does not require preliminary surface treatment. The length of finished products can be from 4 to 12 m.
Bending method
Bending a sheet metal blank to shape it into a corner can be done in several ways:
- The so-called free bending is a manual method, it is used in small artisan workshops or at the household level, it is not carried out on an industrial scale.
- The use of special rolling equipment - sheet metal, pre-cut to the required width, is passed through a special machine, where, due to the mechanical action of the rollers, it is given the shape of an angle.
- Cutting sheet metal and welding individual parts in the shape of a corner is not an efficient option due to high energy consumption and poor quality of the product. It is used in the manufacture of a corner with a large shelf thickness.
The bending method using a rolling machine is considered to be of the highest quality, due to the fact that the destruction of the metal structure as a result of heating does not occur. The corner bent in this way is characterized by high strength and elasticity at the same time.
