Prefabricated steel structure factory buildings must strictly adhere to National Standards (GB), covering critical parameters such as the mechanical properties of steel, the strength of connection joints, and seismic design. For instance, welded components must undergo non-destructive testing to ensure they are free of defects, while bolted connections must meet specific preload requirements to prevent loosening.
In specialized environments-such as petrochemical zones-facilities must also comply with additional standards regarding explosion protection and lightning protection. The design phase is typically handled by professional teams that offer complimentary design optimization services to ensure structural safety and functional suitability. Regarding construction qualifications, the fabrication process requires a Grade I qualification, and installation requires a Grade II qualification, thereby ensuring compliance throughout the entire project lifecycle.
