Roll forming, also spelled rollforming or rollforming, is a type of rolling involving the continuous bending of a long strip of sheet metal (typically coiled steel) into a desired strip passes through sets of rolls mounted on consecutive stands, each set performing only an incremental part of the bend, until the desired crosssection (profile) is obtained.

Tags Rolling Mills; What Is A Rolling Mill? In metalworking, rolling is a metal forming process in which metal stock is passed through one or more pairs of rolls to reduce the thickness and to make the thickness uniform. The concept is similar to the rolling of dough. Rolling is classified according to the temperature of the metal rolled.
We offer hot and cold metal forming machines as well as combination mills that can accommodate both hot and cold rolling applications. Hot rolling is a process in which the metal is heated to above the recrystallization temperature, allowing the material to deform .
This requires the use of reheating furnaces of different designs. Cold forming is often applied as a secondary process for making special steel products such as sheet or wire. There are a number of steelforming processes—including forging, pressing, piercing, drawing, and extruding—but by far the most important one is rolling.
Cold Rolling. Cold rolling is a practical metal working applied to reduce the thickness of metal sheets: several kinds of rolling mills are used, according to the production requirements (hardness of the material, rolling speed, minimum thickness, etc.

Coldstrip reduction mills. A tandem cold rolling mill usually consists of three to five stands of rollers, each of which reduces the strip thickness by about 20 to 40% so that the total reduction in one pass may be by a factor ten.
