Large Span Heavy Duty Steel Frame for Harsh Weather & Seismic Activity Protection Fireproof Anti-Corrosion Custom Size

Our steel structure warehouse adopts a large-span column-free design, which increases space utilization by 30% and is ideal for the operation of forklifts, overhead cranes and other heavy equipment. Built with a heavy-duty steel frame, it achieves 12-grade wind resistance and 9-grade seismic resistance, capable of withstanding typhoons, blizzards and other severe weather conditions. The dual anti-corrosion process of hot-dip galvanizing and electrostatic spraying (zinc coating thickness ≥80μm) ensures a service life of up to 25-30 years. The B1-grade fire-retardant design, with steel frames sprayed with fireproof coating, effectively blocks fire spread and fully guarantees the safety of stored goods.80% of the warehouse components are prefabricated in the factory, with bolt-spliced installation that can be completed in 30-60 days, shortening the construction period by 50% compared with traditional warehouses. The lightweight steel structure design reduces transportation costs by 20% and eliminates the need for large hoisting equipment, significantly saving labor costs. With low later maintenance cost, the warehouse is anti-corrosion and anti-rust, avoiding frequent renovation and being more economical for long-term use. As a cost-effective solution, it is 30% cheaper than concrete warehouses and enables faster production launch, helping enterprises recover investment quickly.The warehouse floor load capacity is ≥500kg/㎡, which can support heavy cargo stacking and large machinery storage. The internal space can be flexibly divided according to different storage needs, suitable for raw material storage, finished product turnover, cold chain logistics and other scenarios. Optional supporting configurations include ventilation skylights, negative pressure fans and thermal insulation rock wool boards, making the warehouse adaptable to tropical, frigid and other climate zones. Reserved fire protection, drainage and circuit interfaces allow seamless integration of intelligent warehousing systems, realizing automated management and improving storage precision and efficiency.We provide full customization services for the warehouse: the span can be adjusted from 8-40m and the eave height from 3-8m, meeting the storage needs of enterprises of different scales. Enclosure materials can be selected from color steel plates, rock wool plates or glass wool plates, balancing cost, thermal insulation and fire protection needs. We support customization of single-span/multi-span and single-layer/double-layer structures, and can expand supporting functional areas such as office areas and sorting areas according to requirements. Small-batch customization is available with a minimum order of 1000 sqm, perfectly meeting the warehousing expansion needs of small and medium-sized enterprises.
