Product Description
Precision Prefabricated Steel Structure Factory Buildings
Modern industrial facilities constructed with high-strength steel as the primary load-bearing material. These bolted portal frame structures are factory-prefabricated and assembled on-site, offering superior performance compared to traditional reinforced concrete construction.
The core structural system utilizes a "steel skeleton" approach where columns, beams, and trusses are manufactured from steel profiles (H-beams, C-beams, Z-beams) and steel plates. This prefabricated modular construction method enables precise manufacturing in controlled factory environments followed by rapid on-site assembly using bolted connections and welding.
