Our hinges are installed on large fire doors for test

Our continuous gear hinge is suitable for all kinds of door frames. The large fire door in the video, with a height of 4.2m and a weight of 250kg, is not enough for ordinary small hinges to support such a large door. Forced use will greatly reduce the service life and performance of small hinges. Therefore, we use a continuous gear hinge with high performance and ultra-long service life, which can bear the weight of 250kg and has high tensile performance.Made of aluminum alloy, it is fireproof, waterproof, corrosion-resistant and light. We are installing it on a large fire door for switch test. It can be seen that opening and closing the door leaf is very silky and smooth, without jamming, and its bearing capacity is also very strong, and the door leaf does not fall. Want to know more about this high-end hinge, you can discuss it with us.
