不銹鋼伸縮門活動部位特點:伸縮門每個活動部位環節均采用不銹鋼管，軸，軸瓦，不銹鋼螺母，尼龍襯墊組裝，組裝時每個環節點加注高級潤滑油，無噪音伸縮自如。
Features of Stainless Steel Telescopic Door Moving Part: Each link of the moving part of the telescopic door is assembled with stainless steel pipes, axles, bearing bushes, stainless steel nuts and nylon liners. When assembling, high-grade lubricants are added to each link point, so that the telescopic door can expand freely without noise.
鋁合金電動伸縮門主體結構與不銹鋼相似，也是假山制作 不銹鋼鑄件 鋁箔真空袋 七孔梅花管 hdpe硅芯管 液壓鋼壩 PVC軟管 飛行激光打標機 瀝青保溫泵利用平行四邊形的運動原理，采用標準的鋁合金型材直接用模具壓制成型，然后通過鍍鋅管以及交叉連桿連接而成。與傳統的不銹鋼電動門相比，材質更優，造型更美觀，更加耐腐蝕。
The main structure of the aluminum alloy electric telescopic door is similar to that of stainless steel. It is also made of standard aluminium alloy profile directly pressed by die, and then connected by galvanized tube and cross connecting rod by using the motion principle of parallelogram. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful, and the corrosion resistance is better.
