Anodizing, powder coating, and liquid paint are the three most common types of surface finishes for Aluminium.

Powder coating is used to prepare Aluminium surface in which finely ground dry paint film is used for electrostatic applications. The powder is melted due to subsequent heat of this film.

Taking care of Aluminium is never complicated. You need to store it indoor in a cool, dry, contaminant, and dust-free area. Be sure not to store Aluminium with other materials.

Acids and bases will cause Aluminium to corrod as they break down the oxide layer. Additionally, if your application is in a marine/offshore enviornment a suitable alloy of Aluminium must be used. Long exposure to water will also cause corrosion in the form of staining

Most of the sheets we stock have stencil marking on it with identifiying marks that tally with the mill test certificate. Some customers also get the sheets checked with a spectrometer at a private test lab.
