What is the maximum wind force that polycarbonate sunshades can withstand?
Polycarbonate sunshades can usually withstand strong winds up to level 12.
This is because polycarbonate material has high strength and good impact resistance. At the same time, sunshades are usually equipped with sturdy brackets such as aluminum alloy, and windproof factors are also considered in the design and installation, adopting reasonable structures and fixing methods to make them have strong windproof capabilities. If a double column carport with thickened high-strength aluminum alloy and elongated thickened hot-dip galvanized steel lining is used, the structural design is scientifically reasonable and can withstand 12 level winds. However, the maximum wind force that the sunshade can actually withstand will also be affected by factors such as installation method, structural design, size, and surrounding environment.
