1. Surface preparation
If required, we prepare the metal surface by sandblasting, sanding or both.
2. Acid bath
Aluminium products are dipped in sulphuric and hydrofluoric acid baths and chromate conversion coating to remove impurities and improve adhesion.
3. Powder coating
The product is then electrostatically coated in colour powder.
The colour powder is then cured onto the product by firing in our large powder coating oven at 200°c.
