Calculation method of width and height of electric telescopic door size
电动伸缩门尺寸之宽高的计算方法
Electric retractable door per meter price and size has a great relationship, electric door retractable door commonly used door body width size of 630,750,800, the standard height of the electric retractable door is generally 1.6 meters, in the choice of electric retractable door, to tell the manufacturer the size of the door, in order to determine the appropriate height and width, of course, if the door is not suitable,
电动伸缩门每米价格和尺寸有着很大的关系的，电动门伸缩门常用门体宽度尺寸为630，750，800，电动伸缩门的标准高度一般是1.6米，在选择电动伸缩门的时候，要告诉厂家门洞的大小，以便确定合适的高度与宽度，当然了，如果门洞不合适，
Then it will cause damage to the electric retractable door, resulting in unnecessary losses.
那么就会造成电动伸缩门的碰伤，从而造成不必要的损失。
2, electric telescopic door size length calculation method
2、电动伸缩门尺寸之长度计算方法
In addition to the above to determine the height and width of the electric retractable door, the length is also a very important aspect of the electric retractable door, and the correlation between the length and the price of the electric retractable door is very important, how should the length be determined?
除了以上要确定电动伸缩门的高度和宽度之外，长度对于电动伸缩门也是非常重要的一个方面，而且长度和电动伸缩门价格的关联非常重要，长度到底应该如何去确定呢？
If you already know the length outside the hole, that is, the remaining headroom after the door is completely shrunk, you can calculate the length of the retractable door according to this length.
如果已经知道洞外的长度，也就是大门全部收缩后剩下的净空，就可以根据这个长度来计算需要伸缩门的长度。
In general, the length can be appropriately long, it does not need to be fully expanded, and the telescopic door can not be too short.
一般来说，长度可以适当的长一些，不需要完全的展开，也不能伸缩门过短。
