Prefabricated Steel Structure Warehouse with 50 Years Lifespan Customized Sizes and Sandwich Panels

Low-cost, customizable steel structure warehouse buildings with sandwich panels, available in various sizes to meet diverse industrial storage requirements.

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.

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.
