不锈钢伸缩门活动部位特点
不锈钢采用国际标准不锈钢原材料，经过特殊工艺制管进行折弯焊接定型制成门体。门体永不变型坚固耐用。门体用大小连杆连接而成伸缩门，大连杆连接型式为古币梅花式，小连杆连接成菱型式道闸，美观大方，坚固耐用。
The stainless steel adopts the international standard stainless steel raw materials, and the door body is made by bending, welding and finalizing through special process pipe making. The door body is durable and durable. The door body is connected with large and small connecting rods to form an expansion door. The connecting type of Dalian rod is old coin plum blossom type, and the connecting type of small connecting rod is diamond type road gate, which is beautiful, generous, solid and durable.
不锈钢伸缩门活动部位特点:伸缩门每个活动部位环节均采用不锈钢管，轴，轴瓦，不锈钢螺母，尼龙衬垫组装，组装时每个环节点加注高级润滑油，无噪音伸缩自如。
Features of movable parts of stainless steel expansion door: each movable part of the expansion door is assembled with stainless steel pipe, shaft, bearing bush, stainless steel nut and nylon pad. During assembly, each ring node is filled with high-grade lubricating oil, so it can stretch freely without noise.
铝合金电动伸缩门主体结构与不锈钢相似，也是利用平行四边形的运动原理，采用标准的铝合金型材直接用模具压制成型，然后通过镀锌管以及交叉连杆连接而成。与传统的不锈钢电动门相比，材质更优，造型更美观，更加耐腐蚀。
The main structure of the aluminum alloy electric expansion door is similar to that of the stainless steel. It is also made by using the principle of parallelogram movement, using the standard aluminum alloy profiles directly pressed by the mold, and then connected by the galvanized pipe and cross connecting rod. Compared with the traditional stainless steel electric door, the material is better, the shape is more beautiful and more corrosion-resistant.
