powder coating

Powder coating is a metal coating method that is applied as a dry, free-flowing powder. In contrast to traditional liquid paint, which uses an evaporating solvent, powder coating is generally applied electrostatically and then cured using heat or ultraviolet light. The powder can be made from either thermoplastic or thermosetting polymers. This technique is commonly employed to achieve a thick, resilient finish that offers greater durability than standard paint. ​ We can offer custom flashings in a single or double sided powder coated finish in aluminium or galvanised steel of 2mm gauge and above. We can also provide custom powder coated 0.7mm single skin galvanised profiled cladding sheets. ​Powder coating is a finish that is applied after manufacture, unlike our other coated finishes which are coated in coil or sheet form as raw material. As such powder coated finishes are applied directly to the base metal so no primer coat will be applied underneath. Powder coating is usually single sided (applied to the weather face of the product) The reverse side of the product will be the base metal and the powder coated item will usually experience some bleeding of the top finish at the edges on the reverse. If you require a bespoke colour or would prefer to explore the option of powder coated sheets and flashings please contact us to discuss your requirements.
