Steel Frame Construction for Multi-Storey Buildings | High-Strength & Fast Build

Steel frame building construction by Guangdong Junyou Steel Structure Co., Ltd. is a systematic process that transforms steel components into a safe, durable, and functional building. At its heart is the steel frame—a network of beams (horizontal) and columns (vertical) connected via bolts or welding to form a load-bearing structure. The process begins with design: engineers use BIM (Building Information Modeling) software to create a 3D model of the frame, optimizing for strength, cost, and compliance with local codes. Next, high-grade steel (Q235 or Q355) is processed in the factory: cut to length, welded into beams/columns, and treated (galvanized or painted) for corrosion resistance. Components are then transported to the site, where the frame is erected: columns are secured to concrete foundations, beams are lifted into place and bolted to columns, and bracing is added for lateral stability. Once the frame is complete, secondary systems are integrated: flooring, roofing, wall cladding, insulation, and utilities. This method offers significant advantages over traditional construction: steel frames are lighter (reducing foundation costs), stronger (enabling larger spans), and faster to erect (30-50% quicker than concrete frames). Steel frame buildings also excel in seismic zones, as steel’s ductility allows it to absorb and dissipate seismic energy. From low-rise offices to multi-storey apartments, this construction method delivers a building that is strong, flexible, and built to last.
