Crossing Column Prefabricated Steel Structure Cross Steel Column

We have three H-Section steel production lines, equipped the flame cutting machine, H-Section steel assembly machine, gantry welding machine and shot-blasting machine, paint spray booth. We also put apart the space for the fabrication of heavy-duty and large structure steel components in our workshop. The steel structure has high strength. Compared with the concrete structure, the steel structure beam and the column cross-sectional area are small, which can increase the effective use area. Generally, the cross-sectional area of the high-rise steel structure column accounts for about 3% of the building area, and the cross-sectional area of the high-rise concrete structure accounts for 7%-9% of the building area.
