How much is the customized tangxiayong automatic expansion door / high-grade aluminum alloy expansion door
Tangxiayong electric expansion door has been used for more than one year, and all pins and contact points may rust. High quality lubricating oil can be used. Use pins and contact points in turn to increase lubrication. Remember not to grease the small holes. Whether electrophoretic materials are used:
Generally, the qualified aluminum profile surface of the expansion door is treated by electrophoretic oxidation. After electrophoresis treatment, the surface of aluminum is smooth, bright and durable.
There are other technical means on the market to make the surface of the expansion door temporarily smooth and bright, but after a period of use, the surface will gradually lose its original luster, so pay attention to this when purchasing expansion door products.
Row spacing:
The so-called door spacing refers to the distance between each piece of aluminum material on the surface of the expansion door. For the production cost of products, many manufacturers expand the door row spacing of expansion doors by themselves, which seriously exceeds the industry standard,
It is necessary to know that the price of the expansion door is calculated according to the line gauge, so when purchasing the expansion door products, we should pay attention to this point, not only the total length of the expansion door, but also the row spacing of the door.
Head and base plate quality:
No matter the electric expansion door or the automatic expansion door product, in the use process, the whole door body is driven by the head drive part. Therefore, the weight and strength of the head plate are particularly important to reduce friction
At present, there are three kinds of bottom plates in the market: Cement bottom plate, thin iron plate and cast iron bottom plate. The quality of thin iron plate and cast iron plate is better than that of cement plate, and the price is naturally more expensive.
Customized tangxiayong automatic expansion door
When choosing expansion door products, we should pay attention to its sliding structure and quality. It is recommended to select the expansion door products with double sliding structure for installation as far as possible, because the traditional single sliding structure may become scattered or scattered after a long time of use, while the expansion door of double sliding structure is not.
Structural quality of diagonal bar:
When choosing expansion door products, we should also pay attention to the quality of its diagonal structure. The diagonal structure of the expansion door determines the integrity and straightness of the expansion door. The more times the diagonal bar passes through the main straight bar, the better the integrity and straightness.
