The right finish for the right environment. The right result.
Choosing the right finish starts with understanding your application, because the finish you choose needs to do more than look good.
Every project has different requirements. Some components need a premium architectural appearance. Others need protection against UV exposure, coastal air, corrosion, wear or demanding industrial environments. The finish is an important part of how a product looks, but it is equally important to consider how and where that product will be used.
At Astro Group, we provide professional powder coating and anodising solutions. We help customers select a finishing solution suited to the application, environment and desired result.
Where will your material be used?
Before choosing a finish, consider the environment.
High UV exposure South Africa’s intense sunlight can place significant demands on exterior finishes. For outdoor architectural and fabricated components, the finishing system needs to be selected with long-term appearance and performance in mind.
Coastal environments Coastal air can introduce additional corrosion challenges for metal components. Whether you are working on architectural aluminium, fabricated steel or outdoor installations, the environment should form part of the finishing specification.
Industrial environments Industrial components can experience daily wear, handling, contaminants and demanding operating conditions. The right finishing system can provide an important layer of protection while maintaining the appearance and functionality of the component.
Architectural applications Modern architecture demands more from its materials. Window frames, balustrades, screens, shopfronts, lighting and architectural steel all need to combine aesthetics with durability. The finish is part of the design, and part of the performance.
Powder coating or anodising?
There is no single finish that is right for every application. The best choice depends on your material, environment, design requirements and expected performance.
Powder coating
Colour, protection and design freedom.
Powder coating is an excellent choice for aluminium and steel when a tough, durable and visually versatile finish is required. With an extensive selection of standard colours and the ability to accommodate special colours, powder coating gives designers and manufacturers significant freedom.
Ideal for
- Architectural applications
- Fabricated components
- Steel and aluminium
- Industrial components
- Brackets and enclosures
- Outdoor applications
- Projects requiring specific colours or finishes

Anodising
Aluminium, durability and a metallic appearance.
Anodising is particularly suited to aluminium applications where corrosion resistance, dimensional accuracy and a premium metallic appearance are important. Because the anodised oxide layer is formed from the aluminium itself, it provides a different type of finish to conventional coating systems.
Ideal for
- Architectural aluminium
- Engineering components
- Precision-machined parts
- Hydraulic and pneumatic components
- Marine hardware
- Aluminium extrusions
- Applications requiring a metallic finish

Choose the finish based on the application
Do not make the decision based on colour alone. Before specifying your finish, ask:
- Where will the component be used?
- What material is it made from?
- How much UV or environmental exposure will it receive?
- Will it experience corrosion, wear or frequent handling?
- What appearance does the project require?
- What level of durability is expected?
The answers can help determine the most appropriate finishing solution.
The Astro advantage
Two finishing technologies. One group.
With Astro Powder Coating and Astro Anodising, you have access to two specialist finishing solutions under one group. That means you can discuss your application with a team that understands the different requirements of aluminium and steel, architectural projects, industrial components and fabricated products.
