Aluminium vs Composite: Which Lasts Longer on the Cape Coast?

On the Cape coast, the material your outdoor structure is made of decides how it ages. Salt air, relentless UV and the south-easter are hard on everything. Here is how our two material families, aluminium and composite , actually compare where it counts.

The two materials

Our aluminium is marine-grade extrusion with no ferrous metal anywhere, powder-coated and baked-enamel finished. Composite is a UV-stable, timber-look material over an engineered frame, the warmth of wood without the wood.

Lifespan & corrosion

Aluminium is the longest-lasting option on the coast: it does not rust, and we back it with a lifetime corrosion guarantee. Composite resists rot, insects and moisture and will not warp or splinter like timber, carrying its own multi-year product guarantee.

Maintenance

Both are genuinely low-maintenance. An occasional wash with mild soapy water is the whole routine. Neither needs sanding, sealing or oiling. See the composite care guide for the simple method.

Look & feel

Aluminium reads clean and architectural and takes any colour. Composite reads warm and natural, with timber grain and tone. It is genuinely a style choice, and both perform.

Cost

Pricing is per project, but as a rule aluminium structures and composite structures sit in a similar bracket for the same footprint; automation and span move the number more than material choice does.

Which should you choose?

Choose aluminium for the cleanest lines, longest life and lowest fuss; choose composite for timber warmth without the upkeep. Many homes combine the two, pairing an aluminium structure with composite accents. Not sure? See louvre roof vs pergola too.

FAQ

Does composite fade in the Cape sun?

Quality composite is UV-stabilised and fade-resistant. A slight, even mellowing over the first months is normal for a natural-look product and settles into a consistent tone.

Is aluminium too hot in summer?

Powder-coated aluminium can warm in direct sun, but a louvre roof is adjustable and a covered structure shades the space beneath. Lighter colours stay cooler.

Which is best right on the sea?

Marine-grade aluminium with no ferrous metal is the safest choice front-line on the Atlantic, backed by our lifetime corrosion guarantee.

Can I combine aluminium and composite?

Yes. An aluminium frame with composite detailing is a popular combination and we build it routinely.
