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 pain 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.

Core Product Advantages
1. Superior Structural Performance, High Load-Bearing Capacity and Safety: The steel frame structure boasts high overall rigidity, good toughness, and light weight, reducing its weight by over 30% compared to traditional concrete buildings. This results in lower foundation load pressure, making it suitable for complex sites such as mountainous areas and soft foundations. It exhibits excellent overall earthquake resistance, wind resistance, and deformation resistance, with stable joint connections that are less prone to cracking and settlement, ensuring long-term safety and stability.
2. Factory Prefabrication, Significantly Improved Construction Efficiency: Over 95% of the main steel frame components are standardized prefabricated and precision-processed in the factory, requiring only modular assembly on-site. This shortens the construction cycle by 50%–60% compared to traditional buildings, significantly reducing project construction time and helping clients complete projects quickly, put them into use, and recoup their investment.
3. Flexible Space Utilization, Adaptable to Diverse Designs: The flexible column grid layout of the steel frame structure allows for large spans and unobstructed open spaces, unrestricted interior layout, and convenient assembly line layout, equipment placement, and space zoning. Supports multi-story construction, maximizing vertical space utilization. It can be freely partitioned and modified according to needs, adapting to various building functional requirements.
4. High-quality, corrosion-resistant, and durable with a long service life. Utilizing national standard high-end steel and professional rust removal and anti-corrosion processes, it effectively resists oxidation, rainwater, and wind and sand corrosion. The main structure is designed for a service life of up to 50 years. Post-construction maintenance is virtually non-existent, resulting in extremely low operating costs and a long-term cost-effectiveness far exceeding traditional buildings.
5. Fully customized to suit global projects. Single-story/multi-story structures, spans, heights, fire resistance and insulation ratings, door and window ventilation systems, and vehicle systems can be customized according to the client's country's climate, site dimensions, load standards, and building functions, fully complying with local building codes and project requirements.
6. Green, environmentally friendly, low-carbon, and recyclable. The steel frame components have a recyclability rate of over 95%. Construction sites are dust-free and generate no construction waste, making it green and low-carbon. Overall, the cost is economical, with fewer construction materials and lower comprehensive construction costs, meeting global green building standards.
