Door Handles. Sunday , September 16th , 2018 - 22:42:25 PM
In terms of materials used, these are the types of handles commonly found in use. Cast Brass - can be copper finished; nickel or chrome plated; bright satin finished; antique finished. Cast or sheet aluminium alloy - usually anodized; with matt, dyed, satin bright or natural finishes. Metal sheet - can be copper oxidized or stove enameled finish, both black. Wooden handle - made of solid wood with some intricate and ornate carvings in base plate (in lever latch types). Others are plain solid wood for a minimalist design.
Brass door handles are available in variety of types, like reproduction period and antique period brass. Many other types of them are also available in the market and all of them are capable of greatly enhancing the looks of your house. However, the reproduction and antique period brass are like a premium type of brass as they are more durable and last longer than other types. This type of door hardware usually doesn't wear off easily and even when its finish fades away, it will still give an antique look and will match the decoration of your house. Newly installed brass door handles are always radiant, but eventually the wear and tear will cause them to lose their radiance. This wear and tear could be due to stains, grease or any other similar factor that can reduce the glow of metal. As brass is the combination of zinc and copper, it creates a golden color that gives the brass door handles their attractive and shining look.
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.
