    The steel frame is an essential component of a warehouse building, serving as the primary load-bearing structure. The portal steel frame and truss structure are the most commonly used steel frames. The steel frame typically includes steel columns, roof beams, and roof trusses, with the addition of floor beams in multi-layer or mezzanine. In addition to the primary structure, the warehouse building requires a secondary structure comprising braces, tie rods, purlins, wall beams, and stays. The combination of primary and secondary structures results in a complete force-bearing structure capable of withstanding the weight of goods stored within the warehouse building.
