Hot Rolled GB Standard Channel Steel

GB channel steel is one of the national standard hot-rolled structural steels, also known as channel steel and metal channel steel. It is manufactured according to the national standard hot-rolling process. The cross-section standard for hot-rolled channel steel is GB/T 706-2008. Hot-rolled channel steel is mainly used in construction of building steel structures, curtain wall projects, mechanical equipment and vehicle manufacturing. Our factory can provide size arrangements from 5 to 40c. For steel grades, we can provide ASTM A36, SS400, Q2358, 03458, Q345, etc. We have a large number of Chinese standard hot-rolled U-shaped steel in stock for sale, if you need it, please contact us!

structural steel channel Products Details

Channel steel is divided into ordinary channel steel and light channel shaped steel. The specifications of hot-rolled ordinary channel section beam are 5-40#. The specifications of hot-rolled modified channel steel supplied by agreement between the supplier and the buyer are 6.5-30#. Steel channel section is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed panels. Channel steel is often used in conjunction with I-beams.
