Aluminum deck railing – Anodizing is an electrochemical process used on metallic substantially controlled oxidation. Anodizing actually alter the structure of the metal, the harder and somewhat thickening it, the process similar to the way a tough crust is formed on baking bread. This makes the metal durable – only diamonds are harder. The metal does not rust or decompose and are not exposed to salt water damage. Therefore, it is particularly suitable for outdoor applications, such as deck railings. While this is treated metal slightly porous, allowing the dyes to be added to change color.
Anodized aluminum deck railing colors, anodized aluminum can be colored during the electrochemical process. This is called integral color. In this method the dyes are deposited directly into the porous surface of the aluminum before it is sealed. This is a long lasting finish, but the finish is subdued. There is often a bronze tone.
A range of colors typically used in deck railings include rust, forest green, gray, gold, off white and black. These all blend with an outdoor setting. Other common colors are metallic, such as bronze, copper and silver. When you are considering a custom color for your aluminum deck railing, consult the manufacturer for colorfastness. Some dyes will not hold up in applications exposed to sunlight on a regular basis, such as deck railings.
