ALUMASC CAST ALUMINIUM RECTANGULAR DOWNPIPES · COMMON QUESTIONS

Something not answered here? The technical desk takes calls on 0330 0539354
When should I use rectangular instead of circular pipes?
Rectangular pipes sit flat against the wall and suit Georgian or early Victorian façades where you want a clean, low-profile appearance.
Do rectangular downpipes handle the same flow as circular?
Roughly equivalent, though circular pipes of similar cross-section handle flow slightly better. Always check Alumasc’s flow data when sizing.
Are rectangular pipes trickier to install?
They need more precise bracket alignment, as any wall irregularities show up in the straight edges. Take time to plumb and shim brackets if needed.
What bracket types are used?
Usually eared sockets fixed directly to the wall, or adjustable stand-off brackets if the wall surface is uneven or insulated.
Can I connect rectangular pipes to circular hoppers?
Yes, transition adaptors are available for neat connections between differing profiles.
Do the edges chip easily during handling?
The powder coating is tough, but protect edges on scaffolds and trestles. If minor chips occur, touch up before final installation.
Are rectangular profiles more rigid than circular?
Yes, they’re less prone to twisting, which is useful on long, exposed runs or windy elevations.
What finish looks best on rectangular pipes?
Heritage black is classic, but mid-greys and stone colours blend beautifully with brick and render. The flat surface shows off colour better than round sections.
