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.

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.

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.
