The Benefits of Choosing a Door and Window Hinge Company

A door hinge company is a company that produces hardware used in doors and windows. By definition, a door hinge is an object which allows the opening of two doors or windows to open together without the use of a key or turning mechanism; also known as a “hinge”

Door hinges are used for many different purposes, but most often they are used to allow the opening of two doors or windows to open together without any turning mechanism. In some applications, such as those involving large expanses of glass or doors with a large aperture size, it may be necessary to have multiple sets of hinges installed at each opening

Many different types of door hinges exist on today’s market. They can be divided into two major categories: mechanical and non-mechanical (or electric). Mechanical hinges are generally made from metal materials such as steel or aluminum and are heavier than their non-mechanical counterparts because they must support more weight when in use. Non-mechanical hinges are typically made from plastic materials such as nylon and have lower weight ratings than their metal counterparts do. The type of material used for each hinge can vary greatly depending on what it needs to do in order to function properly and safely
