Professional Large Span Prefabricated Steel Structure Buildings
CE ISO Certified Factory with Short Assembly Time
Product Overview
Large-span, heavy-duty prefabricated steel structure buildings utilize high-strength H-beams and box-section steel as the main steel frame, combined with prefabricated truss/space frame secondary structures. Through precise structural mechanics design, column-free designs with spans of 30-100 meters can be achieved, effectively improving space utilization. No additional supporting components are required, making them suitable for heavy-duty, large-space applications.
Components are precisely prefabricated in the factory, and welding processes employ advanced techniques such as submerged arc welding and gas shielded welding. Weld quality undergoes 100% non-destructive testing to ensure structural strength and stability, capable of withstanding heavy loads from equipment and cargo stacking.
