Common Defects in Cold-formed Steel

1. Bending does not meet the standard

Causes: 1). Uneven thickness of raw materials; 2). The diameter of the rolling mill is different.

2. Large size fluctuations

Causes: 1). Improper operation when adjusting the rolling mill; 2). The solid speed is too fast, resulting in significant size fluctuations.

3. There are burrs on the cross-section

Causes: 1). The cutting edge becomes dull, making the gap too large and prone to residue; Slow or improperly installed saw blades can also easily lead to the generation of burrs; 2). There is excess metal extruded from the weld seam. The non-standard welding system can also make it easier to leave burrs during cutting.
