Before PVCu guttering, cast iron was probably the most common material for
gutters and rainwater pipework. It can still be seen on many older houses. It is
strong and durable but can be difficult to maintain as it requires regular painting
to prevent corrosion.
Cast iron may still be specified by the local authority, English Heritage or the
National Trust if a building is listed or in a conservation area. The most common
profiles for cast iron are:
l half round section – visually very similar in shape to PVCu half round
profile
l Ogee section – there are several variations of the Ogee profile manufactured
in cast iron, some that are specific to a particular area, such as Notts Ogee,
which can be found only in the Nottinghamshire area
l deep half round – found on larger buildings.
Cast iron-type fittings and guttering are also available in cast aluminium.
