Our Primary Steel Frame forms the main load-bearing structure of a steel building and typically consists of steel columns, beams, rafters, and rigid connection components. Manufactured from high-quality structural steel according to approved engineering drawings, the frame is designed to withstand dead loads, live loads, wind loads, and other project-specific forces. Each component can be customized in size, steel grade, connection method, and surface treatment. With excellent strength, structural stability, dimensional accuracy, and fast on-site assembly, primary steel frames are widely used in industrial workshops, warehouses, logistics centers, aircraft hangars, commercial buildings, and agricultural facilities.
