Iron hinge price is relatively low, but the quality difference is large. Good quality iron hinge surface will have a layer of anti-rust treatment, such as electroplating or painting. However, compared with stainless steel and copper alloy hinges, iron hinges have poor corrosion resistance.
The thickness of the hinge is crucial to its bearing capacity and stability. In general, the thicker the hinge, the greater the weight of the door it can bear. For example, for indoor ordinary wooden doors, the hinge thickness of about 3-5 mm is more appropriate; For heavier solid wood doors or metal doors, the hinge thickness may need to reach 5-8 mm. At the same time, the size of the hinge should match the size of the door. The size of the hinge is too small to be installed on the door, which will cause the door to be unstable during the opening and closing process, and it is easy to loose or deformation.
