stainless steel channel

What is stainless steel channel?

Channel steel is a long strip of steel with a groove-shaped cross-section. It is a carbon structural steel for construction and machinery. It is a section steel with a complex cross-section. Channel steel is mainly used in building structure, curtain wall engineering, mechanical equipment and vehicle manufacturing.
In use, it is required to have good welding, riveting performance and comprehensive mechanical properties. The raw material billets for producing channel steel are carbon-structured steel or low-alloy steel billets with a carbon content not exceeding 0.25%.

Channel steel is divided into ordinary channel steel and light channel steel. The specification of hot-rolled ordinary channel steel is 5-40#. The specification of hot-rolled flexible channel steel supplied by agreement between the supplier and the buyer is 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed cabinets, etc. Channel steel is often used in conjunction with I-beam steel.

The production process of stainless steel channel

Blank → Extended hole system → Finishing hole system → Finished product.
