1, 4.0 wall thickness, super national standard profile thickness, more stable and safer. 6060-T6 aviation grade aluminum alloy, high strength, high hardness.
2, the use of Germany imported Ensinger heat insulation strip, high and low temperature transverse tensile characteristic value is higher, thermal aging performance is much higher than the national standard requirements of 22Mpa, durable.
3, the use of high load bearing hinge, Germany Bukaiwei hinge, high load bearing, more durable.
4, can be shaken, pull rod or electric open, micro ventilation, lighting.
