Pre treatment procedures

7 stage zinc phosphate

This system is designed to remove mill-scale, oxide dirt, oil and grease from the substrate and deposit a fine zinc phosphate on to mild steel, zintec and galvanized components in preparation for powder coating. Our tanks have a capacity of 3000 litres and items up to 2000 x 1200 x 900 can be treated. Please always check with us first regarding weight, dimensions and drainage. Zinc Phosphate is used in the automotive industry and is therefore particularly suitable for products designed for exterior use.

7 stage chromate

Our 7 Stage Chrome/Phosphate immersion system is designed to pre-treat aluminium profiles up to 6 metres in length. This system is also used for the preparation of hot dipped galvanised products.

Shotblasting

We perform Shotblasting in our 12ft² purpose-built Shotblast room using chilled iron shot to clean items to Min SA 2½ in preparation for Duplex and Triplex coatings.
