What Are Door Hinges?
A door hinge is a mechanical device that connects a door to its frame, allowing it to swing open and closed with ease. Door hinges typically consist of two plates (also referred to as leaves) joined by a cylindrical pin. The pin acts as the central pivot, enabling movement. These hinges come in various styles, sizes, and materials, with designs tailored for specific applications. Though their primary purpose is functionality, the right hinge can also enhance a door’s aesthetics. Some hinges are visible and can complement a design theme, while others, like the concealed hinge, are hidden for a seamless and modern look.
Types of Door Hinges
Door hinges are not one-size-fits-all. They come in many different types, each suited for unique applications. Below are the most common types and their uses:

Uses: Commercial doors, lockers, and toolboxes.
Materials: Metal alloys, including stainless steel or brass.

Designed specifically for cabinetry, overlay hinges allow doors to sit over the frame of the cabinet rather than flush with it.

Uses: Glass doors, large pivoting entryways, and decorative installations.
Materials: Steel or other heavy-duty metals.
Advantages: Sleek design, enhanced functionality, and space-saving.
