Cast Iron Half Round vs Cast Aluminium Half Round

Alumasc Heritage cast aluminium half round is designed as a direct replacement for cast iron half round. Cast aluminium weighs roughly a third of cast iron, never rusts, never needs painting, and carries a 40 year guarantee. Cast iron is heavier, requires painting every 3 to 5 years, and has no manufacturer guarantee. However cast iron is the original material and some conservation officers on listed buildings require genuine cast iron rather than aluminium. If your local authority accepts cast aluminium, it is the more practical choice for most restorations.
