Our Q355 prefabricated portal frame steel workshop is built with high-strength low-alloy Q355 structural steel, delivering excellent load-bearing capacity, structural rigidity and seismic performance for industrial scenarios. All components are precision manufactured in factory and assembled on site, which significantly shortens construction cycle and reduces on-site construction waste. The product supports full customization in span, eave height, roof slope, crane beam configuration, mezzanine floor and functional accessories. With optional hot-dip galvanizing or professional anti-corrosion coating systems, it ensures a 50-year design service life and adapts to inland, coastal and various industrial environments. Compliant with ASTM, AISC, AS/NZS and other international standards, it is widely applicable to manufacturing plants, processing workshops, industrial parks and warehouse-workshop integrated projects.

Single Span Steel Warehouse With Overhead Crane is a heavy-load prefabricated metal workshop. It fits heavy manufacturing, bulk storage and mining component stacking scenarios with built-in crane beams for strong bearing capacity. We self-develop thickened H-beam load-bearing technology and own full CNC production lines. Hundreds of sets are sold yearly with ready steel components in stock for fast delivery. Many cooperation cases with global heavy industry clients are completed. This single span metal workshop supports 5-50 tons overhead cranes. Prefabricated parts cut construction time, balancing load resistance and cost efficiency.
