SINHAI: Leading Polycarbonate Sheet Manufacturer in China

Sinhai’s 10mm twinwall polycarbonate sheets feature a two-layer hollow design, optimizing thermal insulation and structural stability for roofing and cladding. The twinwall structure provides a thermal barrier with U-values around 2.2 W/(m²·K), reducing heating and cooling costs by up to 30%. With 70–75% light transmittance, these sheets are suitable for applications requiring diffused lighting, such as pergolas and carports. Treated with SABIC resins and Lotte UV technology, they resist weathering and maintain clarity over decades. The sheets are fire-rated, impact-resistant, and compliant with RoHS and CE standards.
