Product Overview
Our GB ASTM Standard Prefab Portal Frame Steel Structure Warehouse offers superior performance compared to traditional concrete structures. All components are factory-prefabricated for efficient on-site assembly, resulting in excellent structural integrity, shorter construction timelines, and enhanced resistance to wind and seismic activity.
The lightweight steel construction minimizes collapse risks during natural disasters while reducing environmental impact through dust-free assembly and material recyclability. Our structures provide greater usable space compared to concrete buildings of equivalent specifications.
