How do I size a rainwater head correctly?
Match the outlet to the downpipe and ensure the head volume and weir provision can accommodate peak flows at the eaves. Access plates up-line make maintenance easier.
What outlet positions are typical?
Bottom outlet as standard with side outlets available to line up with offsets. Choose to suit façade features and drainage positions.
What finish is best for visible fronts and dates/crests?
Factory two-pack paint gives clean edges on cast motifs, with custom RAL colours for heritage schemes.
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.
