ABSTRACT --- Extruded aluminum parts often serve both functional and
decorative duties, which is why choosing the best finish is an important decision.
There are many coating choices for aluminum extrusions. Liquid finishing has
long been the industry standard for parts up to 40 feet. Liquid provides short-run
capability, fast color change, thin film builds, and in-house color matching.
Advances in coating materials and technology offer other options for treating
aluminum extrusions to provide surface protection and an enhanced appearance.
