Fast Erection Recyclable Metal Frame Structure Prefabricated Logistics Warehouse

The fast erection recyclable metal frame structure prefabricated logistics warehouse is a modern, eco-friendly, and high-efficiency modular building solution specially designed for logistics storage, industrial warehousing, cargo distribution, and temporary and permanent industrial storage scenarios. Adopting advanced factory prefabrication and on-site bolted assembly technology, this metal frame warehouse abandons traditional concrete pouring construction modes, realizing rapid installation, flexible disassembly, complete recyclability, and reusable utilization of building components. It perfectly solves the points of long construction cycle, high resource consumption, poor flexibility, and non-recyclable waste of traditional warehouse buildings. This product is widely applicable to e-commerce logistics parks, industrial factory storage, port cargo stacking, municipal temporary storage yards, and cross-border logistics transit warehouses, providing enterprises with low-cost, high-durability, and green sustainable storage space solutions.

Different from ordinary prefabricated buildings, this metal frame warehouse takes recyclability and rapid erection as core design concepts. All steel structural components are standardized and modularly produced in ISO-certified factories, with unified specification and precise size. On-site construction does not require complex welding, concrete curing, and large-scale foundation treatment, which greatly shortens the project delivery cycle. Meanwhile, all main frame components can be completely disassembled, transferred, and reused after the end of the service cycle of the warehouse, which greatly reduces the enterprise’s construction investment cost and construction waste discharge, conforming to the global green building and low-carbon development trend.

First of all, it has outstanding fast erection performance. The whole building adopts a prefabricated modular design, with 95% of structural components completed by integrated processing in the factory. On-site construction only needs mechanical hoisting and bolted splicing, without on-site welding and anti-corrosion painting operations. Compared with traditional concrete warehouses and ordinary welded steel warehouses, the construction efficiency is increased by 40%-60%. A standard 1000㎡ logistics warehouse can be fully completed and put into use within 2-3 months, effectively shortening the enterprise’s project investment cycle and realizing rapid production and storage operation.

Secondly, full recyclability and reusability are the most distinctive features of the product. All main load-bearing steel frames, secondary purlins, support systems, and connecting accessories are made of high-strength recyclable metal materials. The bolted connection mode realizes zero damage disassembly of components. The disassembled steel components have no structural performance loss and can be directly transported to other sites for secondary assembly and use. The residual value of components is extremely high, reducing the overall construction cost of enterprises by 25%-35% compared with traditional buildings, and greatly reducing construction solid waste, meeting LEED green building certification requirements.

In addition, the product has excellent structural stability and environmental adaptability. Optimized metal frame structure design achieves a high strength-to-weight ratio, which not only reduces the self-weight of the building but also ensures super load-bearing capacity and wind and seismic resistance. The overall structure is lightweight and rigid, with strong deformation resistance, and can adapt to complex terrains such as flat ground, gentle slopes, and hardened ground. At the same time, the surface of all steel components is treated with multi-layer anti-corrosion and rust-proof treatment, which can resist ultraviolet erosion, rainwater corrosion, and high and low temperature alternating erosion, ensuring long-term stable operation in coastal humid, inland dry, and high-altitude cold environments.

Moreover, the product has strong customization flexibility and low maintenance cost. The clear span of the warehouse can be freely customized without internal columns, maximizing the utilization rate of storage space and facilitating the passage of forklifts, pallet trucks, and large storage equipment. The roof and wall enclosure materials support diversified matching, with heat insulation, fire prevention, sound insulation, and waterproof functions. The later maintenance process is simple, with low daily maintenance cost and no regular large-scale reinforcement and renovation required.

The main load-bearing frame (columns and main beams) adopts Q355B high-strength low-alloy H-section steel, with a yield strength of ≥355MPa and tensile strength of 470-630MPa. The steel thickness is customized from 8mm to 12mm according to the span and load demand, with stable mechanical properties and strong pressure resistance. The secondary structural components including roof purlins, wall purlins, knee braces, cross braces, and tie rods adopt Q235B hot-dip galvanized C/Z section steel, with a galvanized layer thickness of ≥85μm, which effectively isolates air and moisture and avoids rust and corrosion. All connecting bolts adopt high-strength 8.8/10.9 grade galvanized bolts, with strong shear resistance and tensile resistance, ensuring the firmness and stability of the connection node.

The product supports fully customized size design. The single clear span ranges from 6m to 36m (no internal columns), the eave height ranges from 4m to 15m, and the building length can be extended infinitely according to actual site demand. The standard floor load-bearing capacity is 2.0-5.0kN/㎡, which can meet the stacking demand of most industrial goods and logistics parcels. The roof live load is 0.5-1.0kN/㎡, adapting to daily rainfall and snowfall accumulation load. The internal space has no shelter, with a space utilization rate of more than 98%, which is 15%-20% higher than that of traditional column-type warehouses.

Wind resistance grade: up to Grade 12 (wind speed ≤32.5m/s), suitable for coastal typhoon-prone areas; Seismic resistance grade: meets seismic fortification intensity of 8 degrees, adapting to most seismic zones; Waterproof grade of roof and wall: IP65, with integrated waterproof and drainage design, no water leakage in rainy days; Fire resistance grade: the enclosure panel can reach Grade A fire resistance, and the overall structure passes standard fire protection detection; Service life: the main steel frame has a service life of 50 years, and the enclosure and auxiliary materials have a service life of 15-20 years. After component replacement, the main frame can be reused for multiple cycles.

Assembly mode: full bolted assembly, no on-site welding; Construction cycle: 30%-50% shorter than traditional concrete warehouses; Recyclability rate: 100% of main steel components can be disassembled and reused; Energy saving performance: the insulation sandwich panel reduces indoor temperature difference, saving 30% of building energy consumption annually; Construction labor cost: 40% less on-site workers than traditional buildings, effectively saving labor and time cost.
