30x80 Heavy Structural Fabrication Prefabricated 3D Drawing
Product Description
Prefabricated heavy steel structure buildings represent innovative construction solutions offering economical pricing, convenient transportation, and quick installation. These structures are composed of H steel columns, H steel beams, purlins, roof sheets, wall sheets, rolling doors, and windows. The main structural components (H columns & beams) are secured with high-strength bolts, while purlins are fixed to columns and beams using 4.8S bolts, enabling faster erection compared to traditional concrete systems. The roof and walls utilize lightweight steel sheets or sandwich panels for efficient assembly.
Product Parameter
