Low-cost, customizable steel structure warehouse buildings with sandwich panels, available in various sizes to meet diverse industrial storage requirements.
Structural System
Connection Components
High-strength bolts: 8.8-grade and 10.9-grade torque-shear high-strength bolts manufactured in strict compliance with ISO 4014 and ISO 4017 standards. These bolts ensure reliable connections and facilitate convenient on-site installation and maintenance.
Welding materials: E50 series electrodes for manual welding and ER50-6 welding wires for gas-shielded welding. This ensures welding quality matches the steel specifications with weld strength not lower than the base metal.
Enclosure Panels
Wall System
Outer layer: 0.6mm-thick colored aluminized zinc profiled steel sheet with 150g/㎡ aluminized zinc content. Excellent corrosion resistance with long-lasting bright colors and multiple color options for different architectural styles.
Insulation layer: 50-150mm-thick glass wool felt with thermal conductivity ≤ 0.04W/(m*K). Provides superior heat insulation and preservation, effectively reducing indoor-outdoor heat transfer.
Inner layer: 0.4mm-thick white color steel sheet with smooth surface for easy cleaning and improved indoor cleanliness.
Roof System
Panel: 0.7mm-thick aluminized zinc color steel sheet with special profiled design for enhanced drainage and wind resistance. Aluminized zinc layer prevents rainwater erosion.
Insulation layer: 100mm-thick polyurethane sandwich panel with thermal conductivity ≤ 0.024W/(m*K). Excellent heat insulation performance reduces roof heat absorption and lowers indoor air conditioning energy consumption.
Waterproof layer: TPO waterproof membrane with superior weather resistance, puncture resistance, and anti-aging performance ensures long-term roof waterproofing.
Dimension Specifications
Span: Standard spans from 12 to 40 meters, with custom super-large-span structures available for large-scale equipment and goods storage.
Length: No fixed limit - flexibly customized according to site length to adapt to various terrain conditions.
Height: Eave height ranges from 5 to 15 meters, accommodating different stacking heights and mechanical equipment operating space. Further adjustments available for special requirements.
Load-bearing Performance
Roof load: Uniformly distributed live load of 0.3-0.7kN/㎡, with specific designs based on regional snow load standards for extreme weather safety.
Floor load (mezzanine): Designed load capacity up to 2.5kN/㎡ for heavy goods storage and light-processing operations.
Wind load: Resists level 12+ strong winds with precise calculations based on building location wind load values for structural safety.
Seismic performance: Designed according to local seismic fortification intensity, effectively resisting magnitude 7-9 earthquakes using flexible connections and energy-dissipating components.
Door and Window Configuration
Roll-up door: Industrial-grade electric roll-up door made of 0.8mm-thick galvanized steel sheet with opening speed of 0.2-0.3m/s. Features anti-theft, wind-proof, and heat preservation functions with customizable sizes.
Swing-door: Constructed from steel or aluminum alloy materials with high-quality hardware accessories, offering good sealing performance and multiple opening methods.
Light-collecting window: Aluminum alloy-framed double-layer insulating glass windows with 5+12A+5mm glass thickness. Provides excellent heat insulation, sound insulation, and lighting effects with optional opening sashes.
Installation and Service
Prefabricated production: All components factory-prefabricated with high precision and stable quality, reducing on-site construction time and errors.
Installation cycle: 20-45 days for 2000-8000㎡ warehouses, depending on size. Professional installation teams ensure efficient and safe construction.
After-sales service: 5-year structural quality guarantee, 1-year enclosure system guarantee, lifetime maintenance consultation, and 24-hour response to customer needs.
