Colors & Appearance

Transparent ｜ Lake Blue ｜ Grey Blue ｜ Milky White (optional matte / anti-drip / anti-glare)

Applications

• Architectural Lighting: Canopies, skylights, corridors, bus shelters, awnings

• Home & Garden: Carports, greenhouses, sunroom interior partitions

• Agricultural Greenhouses: Seedling houses, flower greenhouses, eco-restaurants

• Commercial & Public Buildings: Pedestrian street roofs, grandstand shading, stadium enclosures

Why Choose PC Hollow Sheet (Compared with Glass / Solid PC Sheet)

• Lighter: About 1/6 the weight of glass of the same area, reducing structural load

• Tougher: Impact resistance hundreds of times higher than ordinary glass, safer

• More Energy-Saving: Hollow cavity reduces heat transfer; summer heat insulation, winter heat preservation

• More Weather-Resistant: UV co-extrusion layer resists ultraviolet rays, slows yellowing and embrittlement

• Easier Installation: Can be cold bent, easily cut, drilled, and installed with H-bars

Design Details

• UV Layer: Effectively blocks over 98% of UV rays, preventing aging

• Anti-Drip Treatment (Optional): Microporous hydrophilic coating guides condensation into a film, preventing water drops

• Sealed Ends: Recommend sealed tape at the top + breathable anti-dust tape at the bottom to prevent dust and mold

• H-Bar System: Aluminum/PC H-bars with 3–5 mm expansion allowance for thermal expansion and contraction

Installation Tips

1. Model Selection: Choose thickness & structure based on span, wind/snow load, and bending radius

2. Drainage Direction: Install with cavities running vertically for condensation drainage

3. Expansion Gap: Leave 2–3 mm gap per meter; drill holes 2–3 mm larger than screw diameter

4. Sealing: Use sealed tape at the top, breathable anti-dust tape at the bottom, and weatherproof sealant on edges

5. Fastener Spacing: Purlin spacing 600–1000 mm (adjust by thickness/load)

6. Curved Installation: Minimum cold bending radius ≥ sheet thickness × 175 (varies by structure)

Selection Recommendations (By Application)

• Canopies / Carports: 8–10 mm double/triple-layer, milky white or grey blue for better shading

• Greenhouses / Garden Rooms: 6–8 mm double-layer, transparent or lake blue, with anti-drip treatment

• Corridors / Commercial Roofs: 10–16 mm triple-layer/honeycomb with aluminum H-bar system

• Partitions / Screens: 4–6 mm double-layer, matte or milky white for privacy

Frequently Asked Questions (FAQ)

Q: Will it turn yellow?
A: With UV co-extrusion layer, yellowing is slow under normal outdoor use; warranty covers abnormal cases per terms.

Q: How is the heat insulation performance?
A: The cavity structure + surface treatment effectively reduces heat transfer; shading colors further improve cooling.

Q: Can it be bent for arches?
A: Yes, cold bending is possible within minimum bending radius requirements, with cavity direction aligned for drainage.

Q: How to clean and maintain?
A: Use neutral detergent and soft cloth; avoid organic solvents and hard object scratching.

Q: Can size and color be customized?
A: Thickness, length, color, structure, and double-sided UV / anti-drip options are all customizable.
