Heavy steel frame

Compared with light steel structures, heavy steel structures feature greater plate thickness, larger cross-section dimensions, superior load capacity, and excellent seismic performance, making them suitable for complex conditions and large-scale projects.
They are commonly applied in industrial plants, bridges, port machinery supports, mining equipment foundations, power stations, petrochemical facilities, and large public buildings. Structural forms include welded H-beams, box girders, truss beams, and lattice columns, tailored to project requirements.
Manufacturing processes involve CNC cutting, heavy-duty welding, heat treatment, and protective coating application to ensure stability and longevity. Surface treatments include hot-dip galvanizing, epoxy coatings, or polyurethane coatings to resist corrosion, wear, and harsh weather conditions. Heavy steel structures allow for wide-span adaptability, relatively short installation periods, and modular assembly to reduce on-site workload.
