SINHAI: Leading Polycarbonate Sheet Manufacturer in China

Sinhai’s honeycomb polycarbonate panels feature a hexagonal multiwall structure, optimizing strength-to-weight ratio and thermal insulation. With 8–16mm thicknesses, these panels offer U-values as low as 1.8 W/(m²·K) and light transmittance of 80–85%, making them ideal for greenhouse roofs and curtain walls. The honeycomb design enhances structural rigidity, resisting wind loads up to 1.5 kPa and hail impacts. Treated with permanent UV blockers, they maintain performance in harsh climates and are certified under ISO 9001 and SGS. Custom colors and embossed finishes are available for aesthetic and functional applications. Contact us to explore honeycomb panel solutions for your project.
