UPVC small trapezoidal panels increase the bending modulus by 25% through the trapezoidal wave peak design, and achieve 12-meter column-free span installation. Its self-cleaning nano-coating is combined with a 15° slope drainage system to ensure zero water accumulation on the platform during heavy rain, and the B1-level flame retardant performance meets the rail transit fire protection standards.
4. Cold chain storage insulation roof
The hollow roof board adopts five-layer co-extrusion technology to form a 2cm thick honeycomb closed-cell structure with a thermal conductivity as low as 0.032W/m·K, which is 40% energy-saving compared with traditional color steel tiles. It is combined with an aluminum foil reflective layer to block 95% of infrared radiation and reduce the compressor operation time by 30% when maintaining a warehouse temperature of -25℃.
5. Villa light guide lighting system
The combined roof adopts a prismatic translucent board + a 3mm thick UPVC impact-resistant layer, which transmits sunlight to the underground space through a fully reflective light guide tube. The illumination value reaches 800lux, and the electric blinds are used to adjust the amount of light entering, achieving a 65% reduction in lighting energy consumption throughout the year.
6. Offshore aquaculture awning
The ASAPVC sheet has no aging after 3000 hours of salt spray test. Its gradient color change technology automatically adjusts the light transmittance (50-20% changes with the intensity of sunlight), providing a bionic light environment for marine cultivation, and with the design of 12-level typhoon-resistant reinforcement ribs, it ensures the stable operation of the marine ranch.
