Steel frame structures are a core prefabricated building product manufactured in China, and are the mainstream main structural form for industrial, commercial, and public buildings. The entire production process is integrated, from steel raw material selection and precision processing to factory prefabrication, standardized quality inspection, sea freight packaging and shipping, and on-site modular assembly.

We strictly select high-quality national standard Q235B and Q355B steel as raw materials. After steel coils and sections arrive at the factory, they undergo dozens of precision processes, including CNC blanking, precision cutting, assembly welding, mechanical straightening, shot blasting for rust removal, and multi-layer anti-corrosion coating, to form a complete set of core frame components such as H-beams, I-beams, channel steel, steel columns, steel beams, and supporting connectors.

All steel frame components are prefabricated in the factory according to standardized procedures, ensuring high precision, strong interchangeability, and good structural stability, completely solving the  points of traditional concrete buildings, such as long construction cycles, excessive weight, difficult modifications, and high costs.

After the steel frame structure is completed, it can be quickly assembled into a complete building by adding cladding panels, doors and windows, ventilation, fire protection, roof drainage, and other supporting systems. The on-site construction utilizes all-bolted assembly, eliminating the need for extensive on-site welding and prolonged civil engineering maintenance, and construction is not limited by seasons or weather.

Prefabricated steel frame buildings possess advantages such as light weight, high load-bearing capacity, strong earthquake resistance, good toughness, multi-story construction capability, and flexible modification and relocation. Adaptable to various complex terrains and climates worldwide, they are widely used in industrial production, warehousing and logistics, commercial offices, public facilities, and other scenarios, making them a highly cost-effective modern building solution for engineering projects both domestically and internationally.
