More about Alumasc Steel Circular Downpipes

Alumasc steel circular downpipes offer a tidy rounded profile that suits both modern and traditional buildings. The coated steel construction provides long term weather resistance while still being lighter and easier to handle on site than cast materials. They are available in a range of diameters and colour choices which allows the system to fit smoothly into different design schemes. Installation is straightforward and produces a secure finish that handles water efficiently from roof to ground. When matched with Alumasc steel guttering these downpipes form a complete and functional rainwater solution that maintains a clean and professional appearance throughout the building exterior.

FAQ

Why specify circular steel downpipes?

They offer smooth flow, strength and a balanced appearance for both commercial and domestic projects.

How are they jointed and fixed?

Usually via swaged sockets or push-fit connections with EPDM gaskets and secure wall clips.

Can they be used with copper or zinc gutters?

Not directly - use non-conductive joints to prevent corrosion if dissimilar metals must meet.

What’s the expected lifespan of Alumasc copper, zinc and steel rainwater systems?

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.

Do these materials require ongoing 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.

Are Alumasc metal rainwater systems sustainable?

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.

How are joints sealed and connected?

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.

Can different metals be mixed in the same installation?

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