Frequently Asked Questions
How large can the clear span be?
Our clear span steel building and large span steel structure systems support column-free spans up to 80 meters using steel portal frame or truss configurations. For prefab wide span requirements beyond 80m, space frame or cable-stayed structures can be engineered.
Do you provide installation guidance?
Yes. Each steel building kit includes detailed erection drawings and installation manuals. We also offer online video guidance and optional on-site supervision. The bolt together steel frame system is designed for easy erection steel construction -- most local contractors can assemble it with standard tools.
What insulation options are available?
We offer thermal insulation metal sandwich panels with EPS (0.034-0.042 W/m*K), rock wool (0.034-0.040 W/m*K), and polyurethane (0.022-0.028 W/m*K) cores. The wall roof insulated panel thickness ranges from 50mm to 150mm depending on thermal requirements, creating a fully insulated steel structure for energy-efficient operation.
What anti-corrosion treatments are available?
We provide Hot Dip Galvanized Anti Corrosion treatment (zinc coating ≥ 275 g/m²) for maximum durability, as well as paint systems including epoxy zinc-rich primer + polyurethane topcoat. The wind resistant metal building and fire resistant steel building options can be combined with any anti-corrosion treatment.
What certifications do your buildings carry?
The company has obtained numerous international authoritative certifications, including CE certification (EN 1090-1), ISO 9001 quality management system certification, ISO 3834 welding quality system certification, ISO 14001 environmental management system certification, and ISO 45001 occupational health and safety management system certification. We have also passed an SGS factory audit.
