Causes of roof cracking of arbor in outdoor parking lot

Causes of roof cracking of arbor in outdoor parking lot;

1, because it is used all the year round, but it is not good at maintenance, so the roof of the shed is exposed to wind and rain, which is so oxidized that the parking shed will expand with heat and contract with cold in summer or when the weather is hot.

2. Due to falling objects from high altitude, it is generally caused by some small sharp objects. Due to the small weight of falling objects, such cracks are pitted.

Because the parking shed is a membrane structure parking shed, I bought inferior membrane material, which is mixed with other impurities such as filling soil. Although the price is cheap, its service life is short. I should pay special attention when buying a parking shed. The identification method of membrane material can use good membrane material which is not easy to catch fire and stink.
