Our Finishes

All our electroplating and anodising processes are carried out in accordance with national, international and customer standards: BS EN, ISO, DEF and MIL.

  • Free certificates of conformity on request.

  • Custom jigs are available on request.

  • Hexavalent chromium free site.


Zinc Electroplating

  • Zinc plating can be defined as: the electrodeposition process in which a substrate metal such as mild steel is covered with a layer of zinc. Zinc electroplating is then passivated to provide its high corrosion resistance and extended lifetime of the substrate metal. 

  • The zinc plating process, including passivation, is entirely chromium VI free and so meets the requirements of the latest legislation.

  • We offer zinc plating with clear passivation which produces a blue tinted layer. This clear passivate is close in appearance to a natural zinc finish, but has significantly better corrosion resistance long term. 

  • We operate using fully automated lines, as well as rack and barrel which allows economic benefit for larger quantities of smaller parts. 

  • We are able to plate to the dimensions of: 2.4m x 0.66m x 1.5m.

  • Our maximum automated line weight is 70kg. Our barrel maximum weight is 40kg. 

Hard Anodising

  • Hard anodising is the electrochemical process of producing a layer of aluminium oxide onto the surface of aluminium. This process is used to produce a thicker aluminium oxide compared to the standard sulphuric acid process. Therefore, resulting in an extra durable surface layer with increased wear resistance.

  • We are able to anodise a variety of aluminium alloys at controlled thicknesses, including specialist high copper.

  • Available in a variety of colours and with the following seals: nickel seal, demineralised hot water seal and PTFE seal (providing the lowest coefficient of friction of any solid).

  • We are able to anodise to the dimensions of: 2.1m x 0.8m x 0.9m. 

Sulphuric Acid Anodising

  • Sulphuric acid anodising occurs as a result of electrolysis. Using electricity and a sulphuric acid electrolytic solution, oxidation of the aluminium surface occurs to form a thin, hard film of aluminium oxide. This surface treatment provides great corrosion resistance and can be dyed in a range of colours.

  • We offer black and clear anodise as well as a variety of colours.

  • Nickel seal, demineralised hot water seal and PTFE seal are also available.

  • We are able to anodise to the dimensions of: 2.4m x 0.8m x 0.9m. 

Tin Plating

  • We offer bright acid tin plating in fully automated lines, rack and barrel.

  • The electroplating process consists of the deposit of a coating of solderable tin plating onto the surface of a material via an electrical current. It is effective for decorative purposes and in adding solderability, electrical conductivity and corrosion protection to the metal substrate. 

  • Our maximum weight is 15kg. 

Conversion Coatings

  • Our automated machine and hand lines provide Iridite NCP, Surtec 650 and Surtec 650V conversion coatings. Each coating exhibits corrosion resistance that is equal to hexavalent chromates even though they do not contain hexavalent.

  • Iridite NCP and Surtec 650 both produce a colourless finish that leaves parts with a silver appearance. Surtec 650V produces colourful and visible layers which are blue-grey iridescent. 


For decorative or practical purposes; metal masking prevents a certain area of the metal part from being electroplated. Masking preserves the electrical contacts by not covering the metal with the finishing solution. This service is available on all metal anodising and zinc processes.
