Cold Roll Forming Services in India

 

Buildings, bridges, storage tanks and railways coaches all have one thing in common. They make use of Cold-formed steel (CFS) sections, also known as cold roll sections. These sections are made via a high-speed process where the metal coil is heated and bent into shape by passing it through a series of roll dies. A cold roll section is basically a uniformly long section which can be a sheet, strip, plate or flat bar.

Process of Manufacturing Cold Roll Form Sections

 The process of forming cold roll sections is fairly simple. A flat strip of metal is taken as the feedstock material and shaped by using a number of roll tools into the desired profile.

●       First, a strip of metal is uncoiled. It is passed through a stack of rollers set in a continuous line. As it passed through the roller stacks, each roller adds a form to it.

●       When the strip reaches the end, it has been formed or moulded into the desired shape. Now, the long strip can be cut into standard sizes for transportation.

●       For complex shapes, more rollers are added and usually, 45-60 rollers can be placed in a single line to achieve a single cold roll form section. The final shape can be a plate, bar or circular rod.

●       For metal sections that require to be welded close at the end, laser welding machines are used. Laser and HF welding machines are quite efficient and economic when a large number of complex shapes are to be formed.

The cold-forming process takes place a room temperature, hence the term "cold". The reason is that at room temperature, metal is usually below its re-crystallisation temperature. This can increase the hardness of the metal by 20%. It also has a more aesthetic appeal and higher tolerance than steel formed by using the hot roll process.

Dewas Metal Sections Ltd. (DMSL) started their journey as a manufacturer of shutter lathe sections. Since their inception in 1979, they have expanded to provide specialised Cold Roll sections and a multitude of other products like electrical sections, ERW Tubes and solar sections.
