Why Choose Cast Aluminium Half Round?

Cast aluminium half round guttering is the most commonly specified replacement for original cast iron half round on period properties. It replicates the authentic appearance and weight of cast iron but will never rust, never needs painting, and weighs roughly a third as much. The 40 year Alumasc guarantee far exceeds what any PVC system offers. For listed buildings and conservation areas, cast aluminium is widely accepted as a like for like replacement for cast iron by most local planning authorities.

Moulded Ogee wider ogee for grander properties with larger roof areas.

Cast Aluminium vs Cast Iron Half Round

Cast aluminium half round is designed as a direct replacement for cast iron half round. The key differences are weight (aluminium is roughly a third of cast iron), maintenance (aluminium needs none, cast iron needs painting every 3-5 years), lifespan guarantee (40 years for aluminium vs none for most cast iron), corrosion resistance (aluminium will never rust), and cost (aluminium is less expensive than cast iron). The appearance from ground level is virtually identical, making it the practical choice for heritage replacements.

Alumasc Heritage Half Round FAQ

Is cast aluminium half round accepted on listed buildings? Cast aluminium is widely accepted as a period appropriate replacement for cast iron on listed buildings and in conservation areas. Always confirm with your local conservation officer before replacing.

What colours is it available in? Any RAL colour. Most popular choices are black (RAL 9005), anthracite grey (RAL 7016), and white. Alumasc will powder coat to any RAL reference on request.

How long does it last? Alumasc Heritage carries a 40 year product guarantee. In practice, well maintained cast aluminium regularly lasts 50+ years.

Can I mix cast aluminium with existing cast iron? Cast aluminium is designed to be visually compatible with cast iron. Adaptors are available to connect the two systems. This is a practical solution when replacing part of a cast iron run while the remainder is still in good condition.

Is cast aluminium suitable for coastal areas? Yes. Aluminium performs exceptionally well in coastal environments. Use stainless steel fixings in marine locations for the best results.

How does it compare to extruded aluminium? Cast aluminium is heavier, more detailed, and closely resembles cast iron. Extruded aluminium (Marley Alutec Evolve) is lighter, cheaper, and suits modern properties. Cast for heritage, extruded for new builds.
