q355D u shaped metal channel Products Details
Channel steel is divided into ordinary channel steel and light channel steel. The specifications of hot-rolled ordinary steel channel section are 5-40#. The specifications of hot-rolled modified channel steel supplied by agreement between the supplier and the buyer are 6.5-30#. Channel steel is mainly used in building structures, vehicle manufacturing, other industrial structures and fixed panels. Channel steel is often used in conjunction with I-beams.
Structural steel channel can be divided into 4 types according to shape: cold-formed equal-edge channel section in steel, cold-formed unequal-edge channel steel beam, cold-formed inner curled channel metal bar, and cold-formed outer curled channel section beam.
The specifications of channel steel are mainly expressed by height (h), leg width (b), waist thickness (d) and other dimensions. The specifications of domestic channel shaped steel range from 5 to 40, that is, the corresponding height is 5 to 40cm.
