Powdercoating Process


Powder coating is a completely dry finishing process which is an environmentally friendly and a cost effective method of applying a finish to a variety of metal products.

The powder used is composed of finely ground particles of pigment, resin and other raw materials which is then sprayed onto the metal surface.

The objects are then placed in a curing oven where the particles are heated and fused forming a sealed skin around the product to minimize corrosion. The result is a high quality, durable attractive finish.

Powder coating is available in a range of Ral, Pantone and BS colours please ask to see our wide range of colours.

DioMet would always recommend items are pre-treated before having the coating applied - See our page on galvanizing :  hot-dip-galvanising

At DioMet we powdercoat most of our architectural steelwork and this finish is most popular on juliet balconies, internal and external mild steel balustrades and banister handrails. Of course this is always as requested by the customer but its certainly something we advise for a maintenance free, high quality finish.

Nylon Coating

In addition to epoxy and polyester-based powder coatings, DioMet are also able to offer nylon finished steelwork. These are “pure” nylon coatings, based on polyamide resin systems, which have the following special properties:


  • Excellent chemical resistance to oils and solvents
  • High resistance to damage caused by impact and abrasion
  • Low friction
  • Long-lasting high quality smooth coating

The non-contaminating nature of nylon coating lends itself to use within food manufacturing industries. Other typical applications are stadium seating and disabled vehicles.
