Anodizing Aluminum

 What is Anodizing?

Anodizing is an electrochemical process that enhances aluminum’s natural oxide layer, creating a durable, corrosion-resistant, and decorative finish. Bonnell Aluminum offers acid etch, clear sulfuric, and two-step electrolytic anodizing with consistent color, strong surface protection, and environmentally responsible performance.
