Description of Factory-Made Clear Solid PC Sheet for Roofing

1. Material Properties

• Exceptional Strength & Impact Resistance: Their impact strength is 250-300 times higher than that of ordinary glass and 10 times higher than acrylic sheets, enabling them to withstand harsh conditions such as hailstorms, falling debris, and accidental impacts without shattering.
• High Transparency: With a light transmittance of 88%-92%, these PC sheets closely mimic the clarity of glass. This ensures excellent natural light penetration, making them ideal for applications where illumination is a priority (e.g., greenhouses, skylights).
• UV Resistance: The surface of the sheets is coated with a specialized UV-protective layer, which effectively blocks 99% of harmful UV rays (UVA and UVB). This not only prevents yellowing, embrittlement, or degradation of the sheet itself (extending its service life to 10-15 years) but also protects human skin, plants, and indoor furnishings from UV damage.
• Wide Temperature Tolerance: They maintain stable physical and mechanical properties within a temperature range of -40℃ to 120℃, resisting cracking in frigid winters and warping in hot summers.
• Flame Retardancy: Compliant with the UL94 V-0 flame retardant standard, the sheets self-extinguish quickly when exposed to fire, reducing the spread of flames and smoke—enhancing safety in architectural and industrial settings.

2. Product Specifications

• Thickness: Available in a range of options to suit different load-bearing and application needs, including 1.5mm, 2.0mm, 3.0mm, 4.0mm, 6.0mm, 8.0mm, 10mm, 12mm, and 16mm.
• Width: Standard widths typically range from 1220mm to 2100mm, with customizable widths available for large-scale projects (subject to factory production capabilities).
• Length:
  • For thinner sheets (1.5mm-5.0mm), the maximum length can reach 30.5 meters per roll (facilitating seamless installation and reducing joint gaps).
  • For thicker sheets (5.0mm-16mm), the maximum length is usually 5.8 meters (to ensure structural stability during transportation and installation).
• Structure: The "trapezoidal" design refers to the sheet’s cross-sectional shape, which enhances its load-bearing capacity (distributing weight more evenly) and water drainage efficiency—critical for roofing applications to prevent water accumulation and leakage.

3. Typical Applications

• Agriculture: As covering materials for greenhouses and plant nurseries, they provide optimal light transmission for photosynthesis while blocking harmful UV rays, creating a stable growing environment for crops, flowers, and seedlings.
• Architecture & Construction: Used in skylights, curtain walls, canopy roofs (for parking lots or building entrances), and lighting sheds for industrial workshops. They replace glass to reduce structural weight (PC is 1/2 the weight of glass) while improving safety and durability.
• Commercial & Advertising: Applied in outdoor advertising signs, light boxes, and display cases. Their transparency and UV resistance ensure vibrant, long-lasting graphics without fading.
• Transportation & Infrastructure: Used for sound barriers on highways/railways (combining transparency and impact resistance) and awning roofs for bus stops or subway entrances (withstanding outdoor weathering).
