Rolling plate steel products are divided into two categories:

1- Electromechanical rolling machine

In these rolls, the transmission path of the rollers is carried out by the electromotor, and the top roller feed is carried out manually by moving the large screws on both sides of the machine, from the wires to the thickness of the sheet of 8 mm and sometimes up to 10 mm And is used up to a length of 3000 mm and has molds in the roller head that are also used for corrugated work and tubing, which is one of the most consumed sheets of the sheet..

2- Hydraulic rolling machine

For bending, sheets that have a thickness of more than 10 mm are used in this way, such as rolling work done by the hydraulic oil pressure applied to the rollers through the jacks.
