Clear Plastic Polycarbonate Transparent Roofing Sheet Panels For Shed Greenhouse

The service life of polycarbonate corrugated roof panels is affected by various factors. Under normal usage conditions, their service life can usually reach 10-20 years or even longer. The following is a specific analysis:

Material quality: high-quality polycarbonate material, with stable molecular structure, strong anti-aging and UV resistance, reasonable additive formula, can effectively resist external environmental corrosion, and its service life can reach 15-20 years or even longer. Poor quality boards may have problems such as yellowing, brittleness, and cracking during use due to insufficient purity of raw materials and poor additive performance, and their service life may only be 10-12 years.

Usage environment: Long term exposure to high temperature, high humidity, and high ultraviolet radiation will accelerate the aging of the board and shorten its service life. For example, in tropical regions or environments with severe industrial pollution, boards may show obvious signs of aging within 10-110 Years. If used indoors or in low UV radiation environments with minimal temperature and humidity changes, the service life may be extended to 15-20 years.

Installation method: The correct installation method can ensure that the board is evenly stressed during use, avoiding stress concentration caused by improper installation and premature damage to the board. If no expansion space is reserved during the installation process, the board may crack due to expansion obstruction during temperature changes, affecting its service life.

Maintenance: Regular cleaning and inspection of roof panels, timely treatment of surface stains and scratches, timely repair of problems found, can effectively extend their service life. If maintenance is not carried out for a long time, excessive accumulation of stains and dust on the surface of the board will affect its transparency and weather resistance. At the same time, some small damages may gradually expand, leading to a decrease in the performance of the board.

Some high-quality polycarbonate corrugated roof panels, under ideal usage conditions and with good maintenance, may have a lifespan of over 20 years. But if the usage environment is harsh and lacks maintenance, its service life may be less than 10 years.
