Construction & Architecture
Aluminium has shaped the built environment for decades, and for good reason. It is lightweight, strong, corrosion-resistant, and available in a wide range of surface finishes that hold up in demanding conditions. For architects, specifiers, builders, and contractors who need consistent, high-quality aluminium supplied, fabricated, and finished to specification, Astro Group has been the reliable choice since 1998.
We supply extruded and rolled aluminium products, fabricate and manufacture to customer specification, anodise in South Africa’s largest selection of colours and finishes, and powder coat for both internal and external applications, all under one roof.
Our Turnkey Approach
We supply an extensive range of extruded and rolled aluminium products, from standard sections to purpose-specific profiles, in mill finish or surface-finished form.
We fabricate aluminium to customer specification. CNC bending, CNC routering, cutting, guillotining, press work and more. We also offer custom extrusion design and development.
We offer the largest selection of anodising colours and finishes available in South Africa, including architectural anodising to 15 or 25 micron thickness specifications, in natural finish and a range of architectural colours.
We provide powder coating services for aluminium extrusions and components in lengths up to 4m, with a wide range of standard colours for internal and external applications.
We offer in-house surface preparation for small components prior to anodising or powder coating, including bead blasting, soda or vapour blasting, and tumbling.

Why Aluminium in Construction and Architecture?
Strength-to-weight ratio
Aluminium is about one third the weight of steel while still offering significant structural strength, making it well suited to applications where weight is a consideration without compromising performance.
Corrosion resistance
Aluminium forms a natural oxide layer that protects it from corrosion, making it inherently suited to external applications and coastal environments. This resistance is significantly enhanced by anodising or powder coating.
Finish versatility
Anodised and powder-coated aluminium is available in a wide range of colours and finishes, giving architects and specifiers the aesthetic flexibility to meet project requirements without compromising durability.
Longevity
Correctly specified and finished aluminium performs well over the long term, reducing maintenance requirements and whole-of-life costs on building projects.
Sustainability
Aluminium is fully recyclable without loss of quality, making it a practical choice for projects with environmental performance requirements.

Why Astro Group for Construction and Architecture?
Construction and architecture projects have specific demands that not every aluminium supplier can meet: long runs of matching sections, consistent anodised colour across different batch dates, tight fabrication tolerances on components that will be installed in high-visibility locations, and a supplier who understands that a delay in material delivery can hold up an entire site.
Astro Group has been supplying the construction and architecture industry since 1998 and our national footprint, with offices and warehouses in Gauteng, the Western Cape, KwaZulu-Natal, and the Eastern Cape, means we can service construction projects across South Africa without the lead time penalties that come with working through a single-region supplier.
For projects where the full service is needed, we can take aluminium from raw extrusion through fabrication, preparation, and surface finishing.
