Heavy Steel Structure House is a high-strength prefabricated building with a solid heavy steel frame, using sandwich composite panels as wall materials. Its main characteristics include strong load-bearing capacity, large-span space performance, high structural stability and excellent seismic resistance. The sandwich composite panels effectively provide thermal insulation, sound insulation and weatherproof functions. Featuring firm structure, long service life and reliable safety performance, it is widely used in large workshops, warehouses, shopping malls, stadiums, industrial plants and other large-scale construction projects. It supports rapid construction and flexible space layout, making it suitable for various large-scale and high-load building demands.
