With hanging wheel sliding structure design way, Brio can make the maximum height of the door by 6m, and to make the width of the door system by 20m. The sliding and folding door system could have 18 fans together and with the max of 250kg for each fan. Good air tightness and water/wind resistance performane(max. wind resistance by 6000pa ) could make sure every systems be safe, even for buildings by the seaside and high-rise. Brio’s sliding and folding door system can be instalLED with alufer section-bar which has the thickness that greater than 2.5mm (maximum thickness: 8mm), to ensure the safety of the structure. The adiabatic lighting LOW-E glasses and the stainless steel hardware guarantee that Brio’s sytem could be used in any state of the environment, even by the seaside or high-corrosion region.
