Sinhai’s corrugated polycarbonate roofing sheets are engineered for outdoor resilience, featuring a ribbed profile that enhances wind resistance (up to 110 km/h) and water shedding. Available in 0.75–3mm thicknesses, these sheets are made from virgin PC with permanent UV protection, ensuring 80–85% light transmittance and long-term clarity. The corrugated design reduces noise from rain and hail, making them suitable for residential and commercial roofs, while the lightweight construction (5–10 kg/m²) simplifies installation with hidden fasteners or clips. Ideal for carports, greenhouses, and industrial sheds, these sheets comply with EN 16240 and GB 8624 fire standards. Custom lengths up to 12 meters and embossed finishes (e.g., diamond texture) are available upon request. Contact us to request samples or discuss bulk orders for corrugated roofing projects.

"I installed Sinhai’s polycarbonate roofing sheets on my warehouse in Texas. The 4mm solid sheets with UV protection have withstood intense sunlight and hailstorms for 5 years without damage. The lightweight design reduced installation costs by 20%, and the corrugated texture provides excellent water runoff. Highly reliable for industrial use."
