Steel structure manufacturer since 2009 · 8 fabrication bases in China
A steel structure is a building or frame whose main load-carrying members are made of structural steel: columns, beams, trusses and bracing, joined by bolts or welds. The floors, walls and roof are carried by that frame.
| System | How it carries load | Typical use |
|---|---|---|
| Portal frame | Rigid column-rafter frames in one plane, braced between frames | Warehouses, factories |
| Braced frame | Pinned beams and columns, diagonal bracing for lateral load | Multi-storey offices, plants |
| Moment frame | Rigid beam-column joints resist lateral load | Buildings where bracing blocks openings |
| Truss and space frame | Triangulated members carry long spans | Hangars, stadiums, roofs |
| Composite frame | Steel acting with concrete (SRC, CFT, composite floors) | High-rise, heavy floors |
Rule of thumb: if the building is short-span, heavy-walled and local concrete is cheap, compare both systems before choosing steel.
