Among them, channel steel support is a frame structure formed by splicing multiple channel steels in transverse and longitudinal directions, which has high strength and stability and can bear large load. In the field of fabricated building, especially in the integrated modular installation system of machinery and electricity, channel steel support is widely used as the core bearing structure.
