Powder coating is an extremely durable method of providing a decorative finish to metals and a range of other materials. Unlike iron or steel, aluminium is not susceptible to rust. Instead, it oxidises, forming a thin layer of aluminium oxide on its surface when it comes into contact with oxygen. This thick layer of corrosion helps to protect the metal beneath. Hard anodising works by thickening the oxide layer, offering increased corrosion protection, and preserving the quality of the metal beneath. Aluminium anodising involves passing an electric current through the aluminium before lowering it into an acid bath, where it becomes the anode in the electrical circuit. The electric current causes oxygen to be released at the anode, which reacts with the aluminium to form an oxide layer. The thickness of the layer is determined by the time the aluminium spends in the tank. There are many different factors that affect the finished design of an aluminium special extrusion, such factors are: Other mating parts, important tolerances, visible surfaces, and the eventual surface finish. With powder coating, the range of colours and patterned designs is almost endless. We supply a comprehensive range of architectural grade polyester powder coatings to meet every requirement. This represents a cost-effective route to achieving an extremely durable and colourful finish. Colours can be chosen from the extensive RAL or BS colour ranges in matt, satin or high gloss, or can be matched to customer specifications in flat, metallic or textured finishes.
