Hinges facilitate the smooth movement of opening or closing of doors. These devices are fixed between the door and the door frame. There are different types of hinges used for a diverse range of applications. Each type has its own set of properties, and applications. Based on their application, the hinges can be categorized into three types – standard hinges, heavy duty hinges, and extra heavy duty hinges. Most of us are aware of the first two types of hinges.
