Bent steel components don’t just “walk out” of the rolling mill. Bent steel members are made of straight materials and are bent by your bending company to your requirements.

The bending process does not affect the strength or structural integrity of the steel. When the shape is successfully bent without any buckling or local cracks in the steel, under actual conditions of use, the component will withstand much less stress than that associated with the bending operation. Once the bending is completed, the member can be expected to perform as needed.

Advantages of cold bending metal profiles

When you need to bend various types of metal profiles, cold bending has many advantages over hot bending.

Whether you are dealing with any other shape of beams, tubes, channel or angle, sometimes 3D, 4D or even 5D bending is required so that they can reach the desired angle.

What factors affect the rebound when the section bending machine is working?

The resilience of the profile bending part refers to the phenomenon that the shape and size change after the plastic deformation of the profile makes the bending part leave the mold.

The degree of springback is usually expressed by the difference between the actual bending angle of the workpiece and the bending angle of the mold after bending, that is, the size of the springback angle.
