Polycarbonate U-Locked Sheet for Roofing and Wall Construction Plastic Panel

A polycarbonate U-locked sheet is a high-performance hollow PC roofing panel with a special integrated U-shaped interlocking structure. Made of premium polycarbonate resin via co-extrusion technology, it features snap-lock installation, excellent weather resistance and structural stability, widely used for daylighting roofing, canopy and enclosure projects.

Unlike ordinary flat polycarbonate sheets, our U-locked PC sheets adopt a seamless interlocking design. They effectively solve water leakage problems caused by traditional screw fixing, feature higher overall structural tightness and wind resistance. Meanwhile, they retain all inherent advantages of PC materials including lightweight, high impact resistance, UV protection and sound insulation, with longer service life and lower installation & maintenance costs.

Yes, it is fully waterproof. The exclusive U-shaped snap interlocking structure enables tight seamless splicing between adjacent panels. There are no exposed screw holes on the outer surface, which completely avoids rainwater penetration. It can withstand heavy rain, typhoon and extreme rainy weather, providing long-term stable waterproof performance for roofing systems.

Absolutely. All our U-locked polycarbonate sheets are coated with a high-density anti-UV co-extrusion layer on the surface. It can block 99% of harmful ultraviolet rays, effectively preventing sheet yellowing, embrittlement and aging. The panels maintain stable light transmittance and mechanical properties for 10-20 years under long-term outdoor sunlight exposure.

The product has ultra-high impact resistance, which is 200 times stronger than glass and 30 times stronger than acrylic sheets. The integrated U-lock structure enhances the overall toughness of the roof system. It can resist hail impact, strong wind, falling objects and accidental collision without cracking or breaking, suitable for harsh outdoor environments.
