If we had known the characteristics of continuous geared hinge earlier, we would not have suffered the loss of traditional hinge.

Continuous geared hinge is a widely used hinge type, which appeared in the public's field of vision only ten years ago. It combines the light weight, high strength and corrosion resistance of aluminum alloy with the smooth rotation characteristics of gears. It has enough strength, light weight, corrosion resistance, fire and water resistance, long service life, convenient installation, elegant appearance, high reliability, environmental protection and energy saving.It is famous for its super load-bearing capacity and long service life. Suitable for doors or windows that need to be opened and closed frequently, especially heavy doors and large doors in commercial and industrial places. Its structure usually includes arc-shaped connecting shaft sleeve, left connecting leaf, right connecting leaf, left semi-circular gear and right semi-circular gear, etc., and the smooth opening and closing action is realized through the mutual meshing of gears.

Its length can be customized, and different lengths can be designed according to different needs. For example, the longest continuous geared hinge we have made today is 4.2m long, which is used for large fire doors. The height of a large fire door is 4.2 meters, and each door weighs 250kg. We can connect the door leaf and the door frame of the large fire door with continuous geared hinges and support the whole door, and the door does not fall. Smooth opening and closing, no noise, once again confirmed its excellent bearing capacity. This is why ordinary hinges cannot be installed on large doors.

Although the traditional hinge basically meets the opening and closing requirements of doors and windows, it is not as good as the continuous geared hinge in terms of stability, bearing capacity and various properties. Even so, many people choose it, mainly because of its high cost performance. Can meet the basic needs, but also low cost.

In special use scenarios, such as large tooling doors and heavy doors that need to be used for a long time, continuous geared hinges are still needed, because it is made of aluminum alloy, which has high corrosion resistance and can not be worn in long-term use and various environments. Waterproof and fireproof features also make it less susceptible to external influences.The bearing capacity of more than 250kg is its greatest advantage. The only drawback is its high cost, which is several times as high as that of traditional hinges. However, some people think that an easy-to-use and durable hardware will provide perfect protection for furniture, so many people still choose it.
