What are the Differences Between Hot-Rolled Stainless Steel Channel Steel and Cold-Rolled Stainless Steel Channel Steel?

Many buyers encounter hot-rolled and cold-rolled types when purchasing stainless steel channel steel, yet many do not understand their differences. As a professional manufacturer of stainless steel channel steel, our technicians will clarify this question for you.

The key differences between hot-rolled stainless steel channel steel and cold-rolled stainless steel channel steel are as follows:

1. Cold-rolled formed steel allows local buckling of the cross-section, which can fully utilize the load-bearing capacity of components after buckling; hot-rolled channel steel does not permit local cross-sectional buckling.

2. Hot-rolled and cold-rolled channel steel generate internal stress for different reasons, resulting in vastly different stress distribution across the cross-section. The internal stress distribution of cold-drawn thin-walled channel steel is bending-type, while that of hot-rolled or welded channel steel is membrane-type.

3. Hot-rolled channel steel has a higher free torsional stiffness than cold-rolled channel steel, so hot-rolled channel steel boasts better torsion resistance.

Before purchasing stainless steel channel steel, it is necessary to confirm basic product properties, specifications and price ranges to avoid fraud.
