Powder coating

An immersion painting process in which electrically charged paint particles deposit onto a conductive component under an applied voltage, producing a uniform film that reaches recesses and box sections. It is the standard priming process for car bodies and is also used on many industrial components.

A thermosetting epoxy powder coating applied electrostatically to preheated steel, on which it melts, flows and cures to form a continuous film. It is a standard factory applied coating for buried and subsea pipelines and for corrosion protected reinforcing bar.

A continuous, factory controlled process in which paint is roller applied to coiled metal strip, cured in ovens and rewound before the strip is cut and formed into components. It is the basis of pre-finished steel and aluminium sheet used for roofing, cladding and rainwater goods.

An electrolytic process that thickens and controls the natural oxide film on aluminium and certain other metals, improving corrosion and wear resistance and allowing the surface to be coloured by dyeing before sealing. It is widely specified for architectural aluminium and for aerospace components.
