Product Description
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 future maintenance.
Welding materials: E50 series electrodes for manual welding and ER50-6 welding wires for gas-shielded welding. These materials guarantee welding quality that matches the steel, with weld strength equal to or greater than the base metal.
Enclosure Panels
Wall System
- Outer layer: 0.6mm-thick colored aluminized zinc profiled steel sheet with 150g/㎡ aluminized zinc content, offering excellent corrosion resistance and long-lasting vibrant colors with multiple color options
- Insulation layer: 50-150mm-thick glass wool felt with thermal conductivity ≤ 0.04W/(m*K), providing superior heat insulation and preservation by 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 roof drainage and wind resistance
- Insulation layer: 100mm-thick polyurethane sandwich panel with thermal conductivity ≤ 0.024W/(m*K), delivering excellent heat insulation to reduce roof heat absorption and lower air conditioning energy consumption
- Waterproof layer: TPO waterproof membrane with superior weather resistance, puncture resistance, and anti-aging performance for long-term roof waterproofing
