ANTI-TYPHOON ROLLER SHUTTER
Roll-up doorTONG EANN SHUTTERS CO., LTD
This product is designed to resist strong winds, heavy rain, and other extreme weather conditions. It consists of elegant double-plane aluminum alloy doors with a single-layer door sheet in the middle section to convey a sense of 3D. The patented design is also modeled with integrated guide rails, while another patented “cavity structure” increases stability. According to specification tests, the product can resist an average wind pressure of 5000 Pa (equivalent to 500kg of atmospheric pressure, or 17 Beaufort-level typhoons) without causing damage to the main structure.
