The technology for the production of steel reinforcement is determined by the requirements of GOST. Rebar can be produced in several ways: drawing, rolling, deformation. Drawing is an uneconomical method that requires significant energy consumption. Reinforcement with a diameter of up to 6 mm is obtained by drawing. The production of a bar takes place in several cycles, similar to the production of an I-beam. In the process, thermal and chemical processing of raw materials is carried out.
For the production of reinforcement by the drawing method, special equipment and a significant production area for its installation are required. Manufacturers who do not have the resources to purchase and place such equipment are using alternative methods - for example, micro rolling. It is a more economical technology that uses less steel and less electricity.
Cold forming has become a promising trend in the production of steel reinforcement. Reinforcement with a diameter of 4-12 mm is produced by cold deformation. This method is widely used abroad.
The largest market for fittings is undoubtedly the construction sector. The reinforcement is placed in the mass of concrete to strengthen it. In construction, reinforcing bars of a certain length are required. They are obtained on special machines by the so-called cutting machines for fittings , which are at the disposal of any serious construction project.
The chipper cuts with great force. The knife of the machine is suitable for any shape of reinforcing rods: rods with a round, triangular, square section, as well as steel strips. The machines can be easily moved around the construction site as the equipment is supplied with wheels.
