At present, the electric telescopic doors on the market can be roughly divided into the following categories: painted iron electric telescopic doors, ordinary steel electric telescopic doors, ordinary stainless steel electric telescopic doors, thickened stainless steel electric telescopic doors, ordinary aluminum alloy electric telescopic doors, thickened aluminum alloy electric telescopic doors, refined aluminum alloy electric telescopic doors, etc.
目前市面上的电动伸缩门大致可以分为以下几类：镀漆铁质电动伸缩门、普通钢质电动伸缩门、普通不锈钢电动伸缩门、加厚不锈钢电动伸缩门、精制不锈钢电动伸缩门、普通铝合金电动伸缩门、加厚铝合金电动伸缩门、精制铝合金电动伸缩门等。
The characteristics and service life of electric telescopic doors of different materials are not the same, such as painted iron telescopic doors will be painted off after a period of time, stainless steel telescopic doors are prone to corrosion and rust in coastal areas where the rain is acidic, and aluminum alloy electric telescopic doors are prone to be blown down or blown off in areas with frequent strong winds.
不同材质的电动伸缩门特性和使用寿命不一样，例如镀漆铁质伸缩门使用一段时间后会掉漆，不锈钢伸缩门在雨水酸性较大的沿海地区容易受到腐蚀生锈，铝合金电动伸缩门在强风频繁的地区容易被风刮倒或刮偏。
When choosing materials, consumers must first understand the restrictions on product selection of their electric retractable doors, in the enterprise gates, institutions and other long-term use of the door is recommended to use refined thickened profiles, in construction sites, temporary rental sites can use ordinary profiles, in the coastal industrial development of acid rain more cities, it is recommended to buy aluminum alloy electric retractable doors,
选择材质的时候，消费者首先要明白自己电动伸缩门使用场所对产品选择的限制，在企业大门、机关事业单位大门等长期使用的场所建议使用精制加厚型材，在建筑工地、临时租用场地可以使用普通型材，在沿海工业发达酸雨较多的城市，建议选购铝合金电动伸缩门，
In some typhoon-prone areas, it is recommended to buy stainless steel electric retractable doors.
在一些台风多发地区，建议选购不锈钢电动伸缩门。
