Sinhai’s polycarbonate sunshades are engineered to balance solar protection and light transmission, using 1–6mm solid or embossed PC sheets. These sunshades block up to 99% of UV rays via permanent UV-stabilized coatings while maintaining 50–91% light transmittance, depending on the finish—clear for maximum brightness, tinted (blue/bronze) for heat reduction, or embossed for glare diffusion. With impact resistance 200x stronger than glass and a lightweight design (1.2 kg/m³), they suit residential patios, commercial canopies, and outdoor seating areas. The sheets are compatible with aluminum brackets and can be curved or flat, offering design flexibility. Contact us for sunshade solutions tailored to your climate and aesthetic needs.
