Door hinge is the most common door fitting device that connects the door frame to the door leaf and allows rotation between the two. The hinge can withstand the weight of the door without sagging the door, and allows the door to rotate freely for a long time under the lowest frictional resistance. The hinges come in a variety of materials, including zinc alloy, steel, plastic, and stainless steel. Different materials determine the scope of use of the hinge. The choice of hinges has a very large impact on the use of the door. If an improper hinge is installed on the door, it is not only difficult to play the role of the door, but serious circumstances may endanger life safety. In order for the door to maximize door hanging and gating, it is important to choose the appropriate hinge.
