Architectural Anodizing

In the US, it's virtually impossible to enter a commercial building without seeing storefront framing, curtain walls, door frames and hardware, and partitions that have been manufactured by Walgren customers - and anodized by Walgren anodizing technology.

Anodizing is an electrochemical conversion process that converts the aluminum surface into a hard, durable layer of aluminum oxide, greatly enhancing its resistance to oxidation and corrosion and creating the perfect receptor for dyes, paint primer, or adhesives.

Market leading companies including Kawneer, Oldcastle Glass, Tifton Aluminum and Sapa chose the anodizing process for its versatility, environmental advantages and ability to produce finishes that are both distinctive and functional. They chose Walgren because our anodizing equipment has an unrivaled track record for reliability and performance, and our management and technical team is the most experienced in the world in the highly specialized field of architectural anodizing.

Walgren engineers and builds architectural anodizing systems for continuous run and batch processing. Systems are widely used for aluminum-framed entrances, windows, exterior decorative elements, skylights, and lighting. Each process line is custom-engineered to the specific needs and production environment of the customer, but most lines begin with an alkaline clean, and acid or alkaline etch, deoxidizing and desmutting, followed by type II anodize and 2-step electrolytic color.

Walgren Company has more experience with anodize technology than any company, worldwide.
