Anodized aluminum rectangular tubing is extruded tubing that has been subjected to a secondary process called anodizing. The process is a form of electrolytic passivation which has an effect on the atomic structure of the aluminum; it makes the extruded tube very hard wearing and durable. Although it does make the tube durable, in most instances anodizing is done to increase the corrosion resistance of the metal and as anodizing can be done in different colors, it can also be a way of adding a tough, decorative finish to the final product. Ferrous metals, metals that contain iron cannot be anodized; aluminum is the most commonly anodized metal although magnesium and titanium can also be subjected to the process.
Most metal, ferrous or non-ferrous respond to the working environment by showing signs of surface wear and corrosion. If these are left unchecked, they will eventually reduce the functionality and the appearance of the item. If not attended to, eventually the item will have to be replaced. Anodizing is one of the treatments that can be given to non ferrous metals such as aluminum rectangular tubing, the process slows the effects of wear and corrosion and can add considerably to the life of the product.
An anodized finish which is extremely hard wearing can be applied to just about any product that has been manufactured using aluminum or other non-ferrous metal. One product which is commonly anodized is aluminum rectangular tubing as well as well as round and square tubing. These tubes, as well as many other shapes are produced by extrusion or other processes such as stamping and rolling. To provide the maximum resistance to corrosion, anodizing is normally performed prior to assembly of the finished product, in this way both the inside and outside of the tube is protected.
The oxide layer that is the result of oxidizing is somewhat porous and as such lends itself to various decorative finishes. Although anodizing can be done in various colors, in many cases the aluminum is clear anodized and then painted or dyed to suit. With these properties, anodized aluminum rectangular tubing is an ideal material for the fabrication of outdoor furniture and other items that require strength, durability and good looks.
