Synthetic resin roof panels use a perfluoropolymer surface to build a chemical barrier, tolerate pH1-12 acid-base environment, and cooperate with hollow structures. The thermal resistance R value reaches 1.2m²·K/W, and maintains dimensional stability under a temperature difference of -40℃ to 120℃, becoming the preferred solution for maintenance-free roofs in chemical areas.
3. Light rail platform awnings
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.
FAQ
Q: What is a "Yin-Angle" in roofing, and why is a specific tile needed?
A: A "Yin-Angle" (or Internal Corner) is the concave V-shaped valley where two downward-sloping roof sections meet. This area collects the most water during heavy rain. A dedicated Drainage Tile Sink is essential to prevent water from backing up under the tiles and causing structural damage.
Q: Can this drainage sink be used with metal or clay tiles?
A: While primarily engineered to match the wave profile and material properties of ASA synthetic resin tiles, its flexible drainage design can be adapted for various roofing types. However, for the best waterproof performance, we recommend using it within a compatible resin roofing system.
Q: How does it prevent leakage at the bottom of the valley?
A: The sink features an integrated wide-channel design and deep overlapping edges. When installed correctly beneath the main roofing sheets, it creates a continuous, unobstructed path for water, ensuring no moisture can penetrate the roof deck.
Q: Will debris like leaves clog the Yin-Angle drainage tile?
A: Our tiles feature a smooth, high-gloss surface that discourages debris accumulation. However, like any roof valley, we recommend periodic inspection. The wide-trough design makes it much easier to clean compared to narrow, traditional flashing methods.
Q: Is it resistant to rust and chemical corrosion?
A: Absolutely. Unlike traditional metal valley flashings that can rust over time, our Yin-Angle Drainage Sinks are made from high-grade UPVC/ASA. They are 100% rust-proof and highly resistant to acid rain and chemical fumes, making them ideal for coastal or industrial areas.
