Anodizing is an electrochemical treatment applied to aluminum profiles to improve corrosion resistance, aesthetic appearance, and long-term durability. This process transforms the metal’s surface layer into a hard, protective aluminum oxide. Anodizing is increasingly requested, especially in the naval sector, due to its excellent corrosion resistance and long-lasting performance.
For complete protection, all profiles are anodized only after cutting and processing operations.
For this reason, we can provide products with this finish either as a pretreatment for subsequent painting (commonly called “oxide flash”) or as a final finish.
The “flash” pretreatment is a specific stage of the aluminum chemical pretreatment process performed before powder coating. It creates a thin aluminum oxide layer on the surface to improve paint adhesion and increase the material’s corrosion resistance. An important benefit is that this pretreatment significantly reduces the flow of static currents on the aluminum profile, thereby limiting the formation of corrosion points.
Anodizing at 10–15 or 20 microns with silver color fixation is a final finishing stage that gives the profiles a natural appearance while providing excellent corrosion resistance, high surface hardness, and a uniform, elegant finish. This finish is ideal for architectural and industrial applications and is especially suitable for outdoor environments due to its color stability and low maintenance over time.
