Box columns, welded H-beam columns and round pipe columns are key load-bearing components widely used in steel structure engineering. They are made of high-quality steel plates through welding, forming, straightening and anti-corrosion treatment. With high strength, good stability and reliable mechanical properties, they are widely applied in high-rise buildings, industrial workshops, warehouses, bridges and large steel structure projects.
