The exposed surface area of aluminium extrusion is inherently protected by a naturally occurring, transparent layer of aluminium oxide. This barrier layer forms immediately the newly extruded aluminium is exposed to oxygen and is referred to as 'mill' finish. In many instances, this finish may not be suitable for the product's final application. Where additional surface protection and/or colour is required, East Ocean Glass offers both anodised and powder coated finishing as part of our complete service package.
Powder Coating
Powder coating is an electrostatic process where fine paint particles are sprayed onto the surface of pre-treated aluminium. In a similar way that iron filings attract to a magnet, the coloured powder adheres to the aluminium coating surface due to the electrostatic effect. Once the powder is applied, the aluminium is then baked in an oven to achieve a highly durable, painted finish.
East Ocean Glass undertakes an extensive, chromate conversion pre-treatment process prior to the application of the powder ensuring an improved level of corrosion resistance for the base aluminium surface.
East Ocean Glass is a Dulux and Akzo Nobel approved applicator offering a selection of standard and high durability grade powders in an extensive range of colours, gloss levels and metallic shades.
We are also a licensed applicator of the Effecta process which replicates the colour and appearance of timber grain onto flat-faced aluminium profiles.
