Steel structure building is formed by the main framework through linking up the H beam, C purline, Z purline steel components. Roof and wall using a variety of panels together with other components such as windows and doors. The steel building has the advantages of wide span, high strength, light weight, low cost, temperature protection, save energy, beautiful appearance, short construction time, good effect of insulation, long using life, space-efficient, good seismic performance, and flexible layout.
| Component | Material Description |
|---|---|
| Main Steel Frame | H section steel beam and columns, painted or galvanized, galvanized C section or steel pipe |
| Secondary Frame | Hot dip galvanized C purlin, steel bracing, tie bar, knee brace, edge cover etc. |
| Roof Panel | EPS sandwich panel, glass fiber sandwich panel, rock wool sandwich panel, PU sandwich panel or steel sheet |
| Wall Panel | Sandwich Panel or Corrugated Steel Sheet |
| Tie Rod | Circular Steel Tube |
| Brace | Round Bar |
| Knee Brace | Angle Steel |
| Roof Gutter | Color Steel Sheet |
Advantages:
Steel structure building component system includes primary members (H steel), secondary members, roof and wall sheeting (or sandwich panel) connected to each other. These buildings can be provided with additions such as skylights, wall lights, turbo vents, ridge ventilators, louvers, roof monitors, doors & windows, trusses, mezzanine floors, canopy, bridge crane if need, and insulation.
Our project scope covers prefabricated steel structure workshops, warehouses, garages, logistics parks, high-rise residential buildings, exhibition centers, stadiums, airports, railway stations, and bridges.


To provide an accurate quotation, please provide:
A1: Steel structures offer high strength, durability (up to 50 years), rapid construction time, and lower maintenance costs. They are also environmentally friendly as the materials are recyclable.
A2: Yes, every aspect of the steel structure, including size, layout, roof/wall panels, and additional features like cranes or mezzanines, can be fully customized according to your specific project needs.
A3: During the design phase, we calculate the wind and snow loads based on your local climate data to ensure the structural integrity and safety of the building.
A4: We offer several options depending on your thermal insulation needs, including EPS (Polystyrene), Rock Wool, Glass Fiber, and PU (Polyurethane) sandwich panels.
A5: No, the components are pre-engineered and manufactured in the factory. They are delivered to the site ready for assembly, which significantly reduces construction time compared to traditional buildings.
A6: With proper maintenance and high-quality galvanized or painted finishes, our steel structure buildings are designed for a service life of at least 50 years.
