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 warrantees on powder coated aluminium products.

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