1. For professional daylighting board manufacturers and builders, a really good quality daylighting board, due to its special purpose, its main performance index is the retention of light transmittance and anti-ultraviolet ability, not its tensile strength . Tensile strength is only an item that must be tested for FRP lighting panels.
2. The bending strength of the lighting board will determine the wind pressure resistance of the lighting board. Generally speaking, the bending strength of the lighting board is above 120MPa, and the distance between the purlins is between 1.0m and 1.5m. No matter the thickness of the FRP is 1.2mm or 1.5mm, its wind resistance pressure can reach 1KPa.
