All Alumasc Copper & Zinc Downpipes

They’re self-finished, maintenance-free and evolve a protective patina that enhances rather than degrades over time. Both offer unmatched design life and a premium aesthetic.

Copper begins bright and turns deep brown, then green over time. Zinc moves from bright grey to soft matte grey or blue-grey depending on climate and orientation.

Yes. They perform exceptionally in temperate zones, provided acidic runoff from timber or bitumen roofs is avoided and compatible fixings are used.

Copper and zinc systems can last 80–100 years in the right environment, developing a natural patina that protects the metal. Galvanised or coated steel systems generally last 40–60 years depending on coating type, exposure and maintenance.

Minimal maintenance is needed. Periodic clearing of leaves and checking fixings is sufficient. The metals naturally form protective oxide layers or coatings, so repainting is not required unless specified.

Yes. Copper, zinc and steel are all infinitely recyclable with minimal loss of quality. Alumasc sources responsibly produced metals with high recycled content and low embodied carbon.

Most systems use mechanical joints or sliding connections with EPDM or neoprene gaskets. Copper and zinc are usually jointed by soldering, standing seams or hidden clips, while steel systems use push-fit or bolted unions with gaskets.

Mixing dissimilar metals should be avoided due to galvanic corrosion risk. Always use separation layers, same-metal fittings, and compatible fasteners recommended by Alumasc.
