  5. Powder Coating

Polyester Powder Coating is a complex organic colour layer. The process offers an extended life for the fence and gives it a bright colour coating, available in over 60 standards and over 1,000 non-standard colours in RAL and British Standard ranges. In addition, Zaun’s powder coating meets the requirements of BS EN 134838:2005, which includes subjecting the galvanised steel to a multi-stage pre-treatment before the organic powder coating being applied. This pre-treatment ensures that our coatings offer the highest level of performance on the market.

The Process

Fence Powder Coating As Standard

All Zaun posts/panels/gates and painted auxiliary components (for example, clamp-bars, slide bolts etc.) benefit from a protective zinc layer and electrostatically applied polyester powder coating to BS1722 p16. Care is taken with pre-treatment to ensure sound adhesion between the zinc and paint layers. In a UK C1 environment, as defined in ISO 12944 p2, this should ensure a useful life expectancy of the fence of at least 15-20 years. Life expectancy in all environments can be extended by maintaining the fencing with regular washing. Useful life will be reduced if the fencing is damaged. Any coating damage should be repaired to reduce the effect on useful life.

Enhanced painting systems such as marine coatings are also available for improved life expectancy in C2-C5M environments.
