A door hinge is a crucial hardware component that connects a door to its frame, allowing the door to open and close smoothly.

Door hinges come in various materials such as stainless steel, brass, and iron. They are available in different sizes and styles to suit different types of doors and applications.

These hinges are designed to bear the weight of the door and withstand the stress of repeated opening and closing. They typically consist of two leaves connected by a pin, which allows for rotation.

Some door hinges have features like adjustable tension, which can be used to control the speed at which the door closes. Others may have decorative finishes to enhance the aesthetic appeal of the door and its surroundings.

In conclusion, door hinges play an essential role in ensuring the functionality and longevity of doors.
