Product Description
Crossing Column Prefabricated Steel Structure Cross Steel Column
We have three H-Section steel production lines, equipped with flame cutting machines, H-Section steel assembly machines, gantry welding machines, and shot-blasting machines with paint spray booths. Our workshop includes dedicated space for fabricating heavy-duty and large structural steel components.
The steel structure offers high strength. Compared with concrete structures, steel structure beams and columns have smaller cross-sectional areas, increasing usable space. Typically, high-rise steel structure columns occupy about 3% of building area, while concrete structures require 7%-9%.
