Aluminium Chromating

Doogood's 5-stage chromate conversion coating modifies the surface properties of aluminium products to provide an outstanding foundation primer for adhesives and paint and is an excellent corrosion inhibitor and conductivity preserver.

Aluminium chromate coating enhances the aesthetic value of the metal and reduces surface oxidation without a measurable buildup on parts.

Enduring Excellence

Unlike electroplating, which only applies in a thin external coating, the aluminium chromate conversion coating process creates an etched surface on aluminium products, giving lasting protection from corrosion and superior adhesion.

Doogood provides in-house, industry-leading aluminium chromating; our Melbourne facility is equipped with a 5-stage chromate system capable of processing parts up to 7m in length.

This system has been designed to work with warranty projects, aluminium extrusions and façade panels to provide the highest possible standard of aluminium chromating in Australia.

We currently provide aluminium chromating services for custom projects, architectural and commercial applications, aluminium window manufacturers, cladding fabricators and the transport industries.

Aluminium conversion coating is also a requirement of powder coating aluminium to Australian Standards [1627.0-1997].
