Instructions for purchasing spring door closer

In fact, hinges can also be considered as a type of door closer, and here we specifically introduce the floor spring door closer. The so-called floor spring door closer refers to a type of hardware that can automatically close the door. It is often used for the doors of public spaces such as shops, shopping malls, and offices. In home decoration, if a fully glass door is used in the bathroom, floor springs will also be used. Generally speaking, aluminum alloy doors with a thickness greater than 36mm, wooden doors with a thickness greater than 40mm, and all glass doors with a thickness greater than 12mm can use floor springs.

The floor spring can be divided into two types based on its opening and closing methods. One type is equipped with a positioning function, which automatically fixes the door when it is opened to a certain degree. If the angle is less than this, it will automatically close. It is commonly seen in some public places such as hotels and guesthouses. There is another type that has no positioning function, and the door will automatically close at any angle.

There is a distinction between domestic and imported floor spring door closers. The imported quality is good, but the price is expensive, and the market share is not very large. When choosing, it is important to pay special attention to the three types of floor spring: light, medium, and heavy. Light is suitable for doors with a width of 700-800mm, medium is suitable for doors with a width of 800-1000mm, and heavy is suitable for doors with a width of 1000-12000.
