There are many types of materials for door hinges, such as iron, stainless steel, copper, aluminum alloy, etc. Among them, stainless steel door hinges have a long service life, high strength, and rust resistance, making them one of the most common and widely used door hinge materials in the current market.
2. Classify by structure

Flat panel door hinges are suitable for situations where the door is light and the load is small; Pin type and stopper type door hinges are suitable for situations where the door is heavy and the load is high. In addition, there is an elastic door hinge, which is characterized by a spring structure that can automatically rebound, returning the door leaf to its original position, reducing damage to the door leaf, and ensuring the closed state of the door.
3. Classified by installation method
Door hinges can be divided into two types according to installation methods: pin type and flat type. The plug-in installation method requires drilling holes on the door leaf and door frame, inserting the door hinge into the holes, and then fixing it with a snap ring; The flat installation method directly fixes the door hinges on the door leaf and door frame with screws.
