Over 50 Years of Aluminium Anodising Expertise Delivering Stunning Colours, Corrosion Resistance & Architectural Perfection

Established in 1967, we bring family-owned care and high-tech anodising expertise.
At Universal Anodisers, we specialise in architectural anodising of aluminium sheet and extrusions with striking finishes, including interference colours, using German technology.

Our purpose-built facility in Wetherill Park handles aluminium up to 9 metres in length (clear) and 8 metres for coloured anodising, combining hardcoat satin finishes and an extensive range of 24 colours for internal and external applications.

Working closely with architects, fabricators, and designers, we ensure every project benefits from reduced maintenance, corrosion protection, and long-term value. Our team evolves with innovations in finishing and colour choice

Anodising Applications

Our anodising services are widely applied across popular aluminium components, offering strength, resilience, and flawless finishes that meet functional and decorative requirements.

Door Frames

Durable anodised finishes that protect aluminium door frames from corrosion while providing attractive design appeal for both commercial and residential spaces.

Balustrades

Robust anodising that enhances grip, durability, and style, making balustrades safe and visually appealing in high-traffic areas.

Louvres

High-quality anodised finishes that provide long-lasting performance, weather resistance, and aesthetic enhancement for architectural louvre systems across modern buildings.

Universal Hardcoat offers superior corrosion resistance in colour anodising for architectural aluminium in a choice of 18 exclusive colours – click here.

Anodising thickness can be varied to give the desired level of corrosion and wear resistance:

Achieving a quality finish is paramount.  To help prevent colour variation or ‘tiger striping’, it is important to supply ‘an anodising quality’ sheet. 

The industry is being supplied with both quality and inferior sheets for anodising.  We are suggesting the following steps to alleviate these problems. 

We require anodising grade alloy 5005 H34.  This available through Garmco or Aleris Distributors.  Garmco is from Bahrain, Novelis J575 and Aleris from Germany. Both products provide the anodised finish with metallic lustre.

We recommend trials be run on any alternative aluminium due to varying chemical compositions and to ensure the expected finish is achievable. For large facades please provide a ‘Mill Certificate’ with metal. Metal must be free of any tape, adhesive or oil residue.

Small contact marks are visible on the front face, and 50mm wide contact marks are visible on the back of the panel.  (See Production Gallery for details)

Tags required for clamping purposes should metal be cut to size. Welding rod to be 5356 alloy.
