Steel structure buildings use steel components such as H-beams, I-beams, and steel pipes as the primary load-bearing framework, combined with roofing, wall panels, and flooring systems to form a complete structure.
Compared to conventional concrete buildings, steel structures offer major advantages through factory prefabrication and on-site assembly, resulting in higher strength, faster construction timelines, and better recyclability. These buildings are widely used in industrial plants, commercial developments, residential projects, and infrastructure such as bridges.
Main Components of a Steel Structure Building
A steel structure building typically includes:
- Main Structure: Load-bearing elements such as steel columns, steel beams, and trusses
- Connectors: High-strength bolts, welded joints, and seismic supports
- Enclosure System: Metal roofing panels, sandwich wall panels, and insulation layers
- Floor System: Composite floors made of profiled steel sheeting and concrete, or steel grating
- Auxiliary Structures: Staircases, canopies, and bracing systems

- I Section
- Square tube
- Circular tube
- Floor decking steel sheet
- C Section
- Z Section
- Angle iron
