We have a wide range of BS and RAL colours in stock (see colour chart below) in a variety of finishes and textures. As we deal with multiple international powder suppliers, we are also able to order in special powders if you’re wanting a more unique look. We ensure that all of our powders meet the BS EN 13438:2013 and BS6496 standards. We are unique amongst our competitors due to our ability to powder coat items in a range of sizes. We regularly powder coat small items such as motorcycle parts, tools, radiators and garden furniture alongside large items for the architectural and building industry.
In addition to epoxy and polyester-based powder coatings, Express Coatings also applies nylon finishes. These are “pure” nylon coatings, based on polyamide resin systems, which have the following special properties:-
The coatings are applied by electrostatic spray which means that colour changes are rapid. The thickness of coating enables it to be applied to most metal surfaces.
Any item powder-coated by us is packaged safely for transporting as standard, so no surprise charges! We are also able to offer a local collection/delivery service so please contact the office if you require information on this.
We are able to offer various pre-treatment services including shot blasting, de-greasing and iron phosphate coating.
The Phosphating process is a complex chemical one which involves converting the surface layer of metal into a strong, insoluble metal phosphate. Phosphating creates a rust resistant layer and gives a good base for any coating to be applied. It also gives protection against corrosion. Phosphating solutions usually consist of iron or zinc phosphates dissolved in dilute phosphoric acid. As the solution is applied to the product the reaction between the acid and metal creates a metallic phosphate which forms a layer which is metallic in colour.
Phosphating consists of a 3 stage cycle:
Shot-blasting removes any existing paint or rust and ensures a smoother finish when the item is powder coated. We are able to offer a shot-blasting service for small items, and we can sub-let out larger items to another shot-blasting facility so please don’t hesitate to contact us for more information.
T Wash is a form of pre-treatment used for new galvanised steel and should not be used on weathered galvanising. T Wash is a modified Zinc Phosphate solution which contains a small amount of Copper, when the solution is applied a dark grey or black discoloration of the zinc surface will result.
