More about Alumasc Cast Iron Square Downpipes

Cast iron square downpipes provide clean structured edges that are well suited to historic buildings with defined masonry details or more angular architecture. Their strong build quality and natural weight help them remain securely in position over many years while still achieving authentic period styling. Coating options provide additional resistance to environmental exposure and maintain the visual condition of the product. Multiple sizes are available to meet project demands both functionally and aesthetically. Used along with cast iron guttering systems from Alumasc these downpipes contribute to a complete rainwater system that preserves architectural integrity.

FAQ

What aesthetic does square deliver?

Crisp, formal lines with strong shadow detail that read well on classical and institutional façades.

Does square affect flow or blockage risk?

Square can trap debris at corners more readily than round, so specify leaf protection and schedule rodding points.

How are shoes and bends handled on square?

Use matching square fittings and ensure socket fixings are anchored at each change in direction.

What standards and finishes do Alumasc cast iron rainwater products comply with?

All Alumasc Apex Heritage cast iron gutters, downpipes and fittings are manufactured to BS 460:2002 for cast iron rainwater goods and supplied either factory primed or with a high-performance two-pack painted finish. Factory finishes are certified for long-term protection and colour consistency.

What are the typical lengths, bracket centres and falls for installation?

Most gutters and downpipes are supplied in 1.83 m (6 ft) lengths. Gutters are typically bracketed at 915 mm centres with extra brackets either side of joints, outlets and angles, and set to a fall of roughly 1:600 to 1:350.

How are joints made and sealed on site?

Traditional spigot-into-socket joints are made using a low-modulus silicone or rubberised bitumen mastic, then bolted through the pre-drilled joint holes using corrosion-resistant bolts and washers.

What about durability, repainting and lifecycle?

Cast iron is extremely strong, vandal-resistant and dimensionally stable. Life expectancy is typically 40+ years with correct installation and periodic maintenance. Factory-painted finishes minimise site time; primed goods can be site painted to the required scheme.

Are Alumasc cast iron systems suitable for heritage and sustainable projects?

Yes. They are widely used on listed and conservation properties because they replicate traditional profiles and details, and cast iron is 100% recyclable at end of life.
