Richlands, Brisbane

Six stage process
Tanks 4.5 m long
Dulux accreditation standard

We have a six stage chromating process for the preparation of aluminium: cleaning the surface with acid and water, dipping in chromate and washing in deionised water.

This gives the aluminium protection against corrosion, as well as providing adhesion for the powder coating.

To reach Dulux accreditation standard, we use a reverse osmosis water purification system to achieve iron levels of less than 30 parts per million in our final rinse tank. This allows us to give warranties on powder coated aluminium products.

We can accommodate jobs large and small with our 4500 mm long x 2000 mm high chromating tanks.

What is chromating?

Chromating, also known as chromate conversion coating, treats aluminium and its alloys to improve corrosion resistance and help later coatings adhere.

The metal is cleaned and degreased, then treated with a chromate solution that reacts with the surface to form a thin protective film.
