How to choose and purchase electric stainless steel telescopic doors?

For Xiaobai, who is completely confused about purchasing electric stainless steel telescopic doors, I don´t know how to choose them. Let´s explain the correct selection method for electric stainless steel telescopic doors!

1. Gate truss interval

In response to today´s increasingly competitive electric stainless steel retractable door market, some manufacturers have independently enlarged the door row spacing of retractable doors to reduce production costs, seriously exceeding industry standards. The price of general expansion doors is calculated in linear meters, so most customers only pay attention to the total length of the expansion door and ignore the spacing between the door rows. The basic feature of expansion doors is that the spacing between the door rows can be large or small, and the spacing can be enlarged, which naturally reduces the cost.

2. Sliding structure

The sliding of the telescopic door with a long diagonal rod can be divided into two types: single rolling and double rolling:

Single rolling: There is a support point between the diagonal bar and the main straight bar, and a rolling point is double sliding: There is a support point between the diagonal bar and the main straight bar. At the beginning of the two rolling points, the expansion doors are all of a single sliding structure. After a long time of operation, most of the expansion doors appear to have loose or even loose door leaves. Therefore, manufacturers that attach importance to product quality have changed it to a double sliding structure, despite increasing some costs, But this drawback was dealt with reasonably.

3. Grid structure of diagonal bars

The diagonal bar structure of the expansion door determines the integrity and straightness of the expansion door. The more diagonal bars run through the main straight bars, the better the straightness is. (It can also be determined by the number of grids formed by diagonal bars between the main straight bars in each span, and more grids are appropriate.).

4. After opening, during the process of opening the telescopic door with the left and right neutral dimensions of the diagonal bar, the diagonal bar will slowly tilt. When fully pulled in place, there will be gaps on the upper and lower sides of the diagonal bar. The larger the gap on the upper side, the easier it is to jump, and the more gaps below, the easier it is for animals to cross. In order to save materials, some manufacturers have increased the gap on their own, losing some of the function of the door.
