① Service Life:

Varies from 15 to 25 years depending on thickness and quality. High-quality products can exceed 20 years.

② Light Transmittance:

Reaches 85%-89% (1.5mm thickness, colorless panels). Varies with color and thickness. Premium products maintain 85%±2% long-term transmittance while blocking 99% of UV rays.

③ Flame Retardancy:

Complies with GB/T 14206-2005 national standard. Common ratings: F1 (oxygen index ≥30%) and F2 (oxygen index ≥26%).

④ Impact Resistance:

Exceptional impact strength—250-300 times that of ordinary glass and 30 times that of acrylic sheets of the same thickness.

⑤ Temperature Resistance:

Stable performance within -40°C to 120°C, without high-temperature softening or low-temperature brittleness.

Laying Direction: Install from the eave toward the ridge. The panels directly snap onto the side peaks of steel sheets.

Pre-Drilling: Pre-drill holes before fixing; the hole diameter must be 6-9mm larger than the screw diameter to allow for thermal expansion and contraction.

Overlap and Sealing:

① Longitudinal Overlap: Minimum 200mm overlap, sealed with specialized waterstop tape or neutral weather-resistant sealant.

② Transverse Overlap: Overlap at least one wave peak, similarly sealed.

Fixing Method: Use reliable flashing washers between screws and panels for waterproofing and dust prevention. Insert the washer into the screw and drill into the purlin.

Safe Construction: Never step directly on wave peaks to avoid cracking. Place anti-slip wooden boards laterally on panels for safe footing during work
