Aluminum is rust free, light, strong material, and is ideal for railing and fencing. Where as other materials may offer some of the beneficial characteristics of aluminum, they can not provide the full range of benefits that aluminum can. Aluminum extruding is a versatile metal-forming process that enables designers, engineers, and manufacturers to take full advantage of a wide array of physical characteristics:

Light Weight:
Aluminum has specific gravity of 2.7 and weighs only 0.1 pound per cubic inch. It weighs less by volume than most other metals. In fact, it is about one-third the weight of iron, steel, copper, or brass. Lightweight aluminum is easier to handle, less expensive to ship, and is an attractive material for applications, especially for railing and fencing products.

Strong:
Aluminum profiles can be made as strong as needed for most applications. When temperature falls, it becomes even stronger, so it is most commonly used material in cold area. They resist strains and impacts, often more satisfactorily than traditional materials.

Corrosion Resistance:
The excellent corrosion resistance of aluminum is due to the presence of a thin, hard protective film of aluminum oxide that bonds tenaciously to the surface. This occurs naturally and can reach a thickness of 0.2 millionths of an inch. Further protection can be done by applying paint or an anodize finish. It does not rust like steel.

Appealing Appearance:
Aluminum has an inherent advantage over most other metals because of its attractive appearance and good corrosion resistance. There are many different finishing techniques that can be used. The more common ones are: liquid paint (including acrylics, alkyds, polyesters, and others), powder coatings, anodizing, or electroplating. The high gloss powder-coated finish actually resists ultraviolet rays, helping to keep its low maintenance beauty for years. The powder coating is durable and comes in a huge variety of colours
