Select automatic retractable door:
1, electrophoretic material
The surface of the aluminum profile of the general qualified telescopic door is treated by electrophoretic oxidation. After electrophoresis, the aluminum surface is smooth and bright for a long time and does not fade.
There are some other technical means in the market that can make the surface of telescopic door smooth and bright for a period of time, but after a period of use, its surface will gradually lose its original effect, so we must pay attention to this when purchasing telescopic door products.
2, door row spacing
The so-called door row spacing refers to the distance between each aluminum material on the surface of the retractable door. In order to reduce the production cost of products, many manufacturers widen the row spacing of telescopic doors by themselves, which seriously exceeds the industry standard. You know, the price of retractable doors is calculated by linear meters.
Therefore, when purchasing telescopic door products, we must pay attention to this point, and don't just pay attention to the total length of telescopic doors and ignore the door row spacing.
3, the nose bottom plate quality
Whether it is an electric telescopic door or an automatic telescopic door product, the whole door body is driven by the head driving part during use, so the weight and strength of the head bottom plate are particularly important.
At present, there are three kinds of soleplates on the market: cement soleplates, thin iron plates and cast iron soleplates. The quality of thin iron plate and cast iron bottom plate is better than that of cement bottom plate, and naturally their prices are more expensive.
4, sliding structure quality
When choosing telescopic door products, we must pay attention to its sliding structure and quality. It is recommended to choose the telescopic door product with double sliding structure for installation.
Because the traditional single sliding structure runs for a long time, most telescopic doors will be loose or even fall apart, while the telescopic doors with double sliding structure will not appear this phenomenon.
5, diagonal structure quality
When choosing telescopic door products, we should also pay attention to its diagonal structure, which determines the integrity and linearity of telescopic doors. The more diagonal bars that pass through the main straight bar, the better the integrity and linearity.
6. Manufacturer information
When choosing telescopic door products, we should not only consider the above parts and details, but also pay attention to the manufacturer's information, especially the description of telescopic door products, to see whether there are industry standards, whether they are produced by regular manufacturers and how long the shelf life is.
And try to incorporate these into the purchase contract to ensure their rights and interests.
