1) Material: Aluminum 2) double layer aluminum alloy 3) open way:automatic/manual  1.Material: Aluminum alloy(the double layer slats is shaped by hot extrusion, which more stronger and with the     function of prying resistant) . 2.Duble stats surface: conduct oxidation processes and  painted in the condition of high temperature.With symmetrical coating which hard to flake away, good adhesion, and strong resistant to corrosion,  durable and nice.Using specilized exterior motor with thermel protection device, durable, low noise, easily to install.  3.Running speed : 0.2-0.3m/s,which save the power largely. 4.Noise reduction: the working noise is less than 58 db.   

5.Bottom beam : Thickness:1.7mm

6. Tracks:Thickness:1.7mm
