Holden Aluminium Technologies Ltd

Aluminium Finishing

Holden Aluminium Technologies can supply products in a range of finishes including:

  • As formed/machined - in a mill-finished state.

  • Anodised - this includes a range of anodising thickness and colours depending on application from decorative trim to more demanding application requiring a thick abrasion resistant film. This process is carried out at our in-house anodising facilities in Cheltenham.

  • Painted - a range of painted finishes are offered including wet painted, electrophorectic and powder coated. Again the choice of finish will depend on the application, colour requirements and volumes, particularly for electrophorectic where the economies require higher quantities.

Our technical staff can advise on the appropriate and most effective finishing requirement on request.

Introducing Sapa Lok

Anodising and colours for the surface treatment of aluminium profiles in bronze and black. Sapa Lok is a cobalt-based application.

  • Lock in colour
  • Lock in durability
  • Lock in longevity

A particular benefit of the Sapa Lok process is a highly durable surface coating, with no risk of chalking. Sapa Lok also offers enhanced corrosion resistance combined with high UV stability to ensure colours do not fade.

Anodising

Anodising

One of the most common surface-treatment methods, is used to create:

  • permanent  new appearance
  • corrosion resistance
  • dirt repellent surface that corresponds to a high standard of hygiene
  • decorative surface with durable paint and lustre
  • smooth surface
  • functional surface, a sliding face or an abrasion-proof surface, for machine parts, for example
  • electric insulating surface
  • basis for application of glue and paint

The most common form of anodising is natural anodising. Sapa also delivers profiles with oxide layer impregnated with colour pigment. These include pigments with excellent colour fastness, suitable for outdoor use. Anodising produces a decorative, soil-repellent, corrosion-resistant surface. The surface of the metal is transformed into oxide through electrolysis. the process continues until the thickness of the oxide layer is the desired thickness – usually 5–20 µm. The oxide layer can be dyed, as shown here.
