Product introduction

Steel structure frame

Pre-engineered steel structure with channel steel frames offers a modular building system that streamlines construction through factory-fabricated components, ensuring fast assembly, cost efficiency, and reliable structural performance for warehouses, workshops, and commercial facilities.

Product Advantages

Speedy installation

Pre-engineered components arrive ready to bolt together, cutting on-site labor time by half compared to conventional steel structure systems.

Cost-efficient design

Lightweight channel steel frames reduce foundation requirements and material waste, lowering overall project budgets significantly.

Flexible scalability

Modular building system layouts adapt easily to warehouses, workshops, or offices, allowing future expansions without major structural changes.

FAQ

Q1: What is the maximum span?

A: Our system supports clear spans up to 60 meters without interior columns. Standard beams span 10-30 meters, while heavier girders can go longer for warehouses.

Q2: How does it save costs?

A: It saves money three ways-lighter foundations, faster installation, and no interior columns. This typically cuts 15-25% off total project costs compared to multi-span designs.

Q3: How do you control sagging (deflection)?

A: We use tapered frames, proper beam sizing, and set deflection limits. For spans over 35 meters, we add tie beams or knee braces to reduce the effective span without using floor columns.

Q4: What steel grades are available?

A: We offer ASTM A992 for the US, S355 for Europe, and Q355B for Asia. Stronger grades let us use lighter sections, which lowers steel weight and shipping costs.

Q5: How is corrosion protected?

A: For coastal or humid areas, we offer hot-dip galvanizing (lasts 20–30 years) or weathering steel (Corten). For indoor use, epoxy paint works well and lasts 10–15 years.
