Why Choose Cast Aluminium for Heritage Projects?

It will not warp, fade, or crack, and can be powder-coated to blend seamlessly with traditional facades.

Frequently Asked Questions (FAQs)

Is cast aluminium suitable for listed or heritage buildings?

Yes. Cast aluminium is often recommended by conservation officers due to its visual similarity to traditional cast iron, with the added advantage of being lighter, easier to install, and longer lasting.

How long does cast aluminium guttering last?

With proper installation, cast aluminium gutters and downpipes can last 50 years or more with minimal maintenance.

Does aluminium rust like steel or iron?

No. Aluminium forms a natural oxide layer that prevents rust, making it ideal for coastal or damp environments.

Can I get the gutters and downpipes in a custom colour?

Yes. We offer a wide selection of RAL colour options via durable powder-coated finishes, ensuring excellent colour retention and protection.

Are aluminium gutters and downpipes easy to install?

Yes. They are significantly lighter than cast iron and can often be installed without specialist equipment. Pre-drilled fixing lugs and push-fit joints make the process efficient.
