Material Properties of Aluminum
Aluminum is a lightweight yet durable metal that makes it an excellent choice for outdoor railings. Weighing approximately one-third as much as steel, aluminum railings are easier to install and handle during the construction process. While lightweight, aluminum is also very strong. It has a high strength-to-weight ratio, meaning aluminum structures can support significant weight loads relative to their mass. Aluminum alloy composites commonly used for railings have tensile yields around 35,000 pounds per square inch, giving them ample strength for safety applications.
Resistance to Weather and Corrosion
When exposed to outdoor elements like rain, sun, snow, and temperature changes, aluminum stands up well compared to other materials. It is highly resistant to corrosion and will not rust like steel. The thin layer of aluminum oxide that naturally forms on the metal's surface protects the underneath material. Even in highly corrosive coastal environments, theyrequire little maintenance over long periods. The resistance to corrosion means Aluminum Railings retain their structural integrity and good looks with minimal care needed over many years.
Low Maintenance
Aluminum is a low maintenance material choice for railings. Compared to wood, which requires regular staining or sealing, they require almost no upkeep. Occasional cleaning with a mild soap and water is usually all that is needed to remove dirt, fingerprints or other blemishes from the surface. Harsh cleaners or abrasives are not required. Without corrosion or rot concerns, they do not need painting or sealing like other metals. Their resistance to weathering means they will look new for many years with minimal effort from the homeowner.
Variety of Styles and Finishes
While often associated with a silver or brushed finish, Aluminum Railings come in a wide array of style and color options. Manufacturers can apply powder coatings to the material in any color from bold primaries to subtle earth tones. Textured powder coats provide the visual interest of wood grain or other patterns. Anodized coatings create jewel-tone colors that resist fading for the life of the railing installation. Stainless steel balusters are a popular pairing with aluminum rails and posts for a modern industrial look. Design options include Traditional, Contemporary, Coastal, Craftsman and more. Almost any aesthetic vision can be achieved through creative use of aluminum's varied finishing possibilities.
