SINHAI: Leading Polycarbonate Sheet Manufacturer in China

Sinhai’s 16mm multiwall polycarbonate roof panels combine durability and energy efficiency for commercial and residential roofing. The multi-layer design creates thermal barriers with U-values as low as 1.8 W/(m²·K), minimizing heat transfer and enhancing year-round comfort. With 80% light transmittance and uniform diffusion, these panels reduce glare while maintaining bright interiors. The 16mm thickness provides impact resistance 200x stronger than glass, enduring hail and wind loads up to 1.5 kPa. UV-stabilized coatings prevent yellowing and ensure a 10-year service life. Manufactured from virgin PC material, they meet RoHS, CE, and SGS standards. Custom sizes and colors are available, with fast turnaround from Baoding and Kashgar facilities.
