Prefabricated Steel Workshop – AISC/AWS/EN 1090/AS/NZS Compliant, Custom Industrial Solutions
This prefabricated rigid-frame steel workshop is customized for industrial production and warehousing scenarios. Designed and manufactured to North American, European, Australia-New Zealand international standards, it meets global project access requirements.
Built with welded H-beam main frame, the building achieves up to 60m large clear span without inner supporting columns, fully unlocking interior space for production lines, heavy machinery placement and cargo storage. We tailor structural schemes according to local wind loads, snow loads, seismic parameters and overhead crane tonnage, balancing structural safety and overall construction cost.

Global Standard Compliance
- AISC 360: US official steel building design standard, governs LRFD/ASD calculation, component stability and node connection design
- AWS D1.1: International mainstream structural steel welding specification, regulates welder qualification, welding procedures and weld quality inspection
- EN 1090 EXC2: EU mandatory CE marking certification for load-bearing steel structures, fulfills strict EU factory production control requirements
- AS/NZS 4100 & 5131: Australia & New Zealand steel structure design, fabrication, anti-corrosion and erection standards
Structural Core Advantages
- Ultra-wide unobstructed space: Span range 15–60m, bay width 6–12m; eave height customizable from 4m to above 15m
- Multi-load adaptability: Resists wind, snow and seismic loads, fits overhead cranes up to 50 tons
- Stable auxiliary system: C/Z cold-formed purlins support roof and wall panels; angle steel & rod bracing ensures lateral structural stability
- Excellent seismic performance: Ductile rigid frame effectively dissipates seismic energy
