O’Brien Engineering has developed business relationships with a number of local suppliers. This means we can offer you the following services:

  • Anodising
  • Plating
  • Powder Coating
  • Linishing/Polishing

These services are organised and handled by O’Brien Engineering.


Anodising is an electrochemical process that converts the metal surface into a decorative, durable, corrosion-resistant, anodic oxide finish. Aluminium is ideally suited to anodising, although other nonferrous metals, such as magnesium and titanium, also can be anodised. We have a wide range of colours available.


Plating is a manufacturing process in which a thin layer of metal coats a substrate. This can be achieved through electroplating, which requires an electric current; or through an autocatalytic chemical process.

Powder Coating/Spray Painting

Powder coating is an advanced method of applying a decorative and protective finish to a wide range of materials. The powder used for the process is a mixture of finely ground particles of pigment and resin, which is sprayed onto a surface electrostatically. The charged powder particles adhere to the electrically grounded surfaces until heated and fused into a smooth coating in a curing oven. The result is a uniform, durable, high-quality, and attractive finish.

Spray Painting is a painting technique where a device sprays a coating through the air onto a surface. The most common types employ compressed gas—usually air—to atomise and direct the paint particles.


Linishing is not only used to provide surface finishes such as #4 finish on stainless steel, it is also an excellent method of deburring parts after laser or punching, and will leave the surface with a smooth, even appearance.

O’Brien Engineering can offer polishing on several types of metal, with particular emphasis on stainless steel, brass, aluminium and copper. We are able to offer polishing on all shapes and sizes in flat bar, angle bar, tube and pipe up to 6 metres in length. The finishes we offer are 120, 240 and 400 grit and mirror finish.
