Door handle is an ambiguous term, and includes door latches, bars, and knobs. Depending on the geographical location and its place in time, they vary in design, form and materials. The only constant is its function: an attachment used to open or close a door. The earliest doors extant are approximately 5000 years old. Door handles, as devices to manipulate a gateway, became a necessity shortly after the invention of the pivoting mechanism. To most, pivots are simply known as hinges, however, there are nearly as many hinge designs and configurations as there are handles. The simplest handle is a pull - or push - projection on the side opposite the hinge. The placement of the handle is generally where it will provide an optimal mechanical advantage; most doors operating as second class levers. Doors with centre pulls or rings, or a pivot point in a location other than one edge of the door, use first or third class lever principles.
These Door hardware are made from a variety of materials such as cast brass, sheet aluminum alloy, metal sheet and wood. These are made from cast brass material may be copper finished, nickel or chrome plated, bright satin finished and antique finished. The sheet aluminum alloy handles are available in finishes like matte, dyed, satin bright or natural finishes. The metal sheet may be copper oxidized or stove enameled finish or both black. The wooden come in lever latch types with intricate and ornate carvings in base plate. At the same time, most people prefer to buy Door hardware made from brass and metal for permanent and lasting use.
