FAQ Categories

All FAQ
Are cast iron deep half round gutters suitable for listed buildings?
Yes. Cast iron deep half round gutters manufactured to BS 460:2002 are the heritage-accurate choice for listed buildings and conservation areas. The deep half round profile provides greater flow capacity than standard half round, making it particularly appropriate for large-roofed period properties including country houses, churches, and civic buildings. Tuscan Foundry Products supplies the full range of sections, angles, and fittings.
What is the difference between a deep half round and a standard half round cast iron gutter?
A deep half round gutter has a taller, deeper cross-section than a standard half round, giving it greater capacity to handle heavier rainfall. It is typically specified on larger buildings, buildings with steep or complex rooflines, or any project where the drainage calculations show standard half round to be insufficient. The profile is otherwise similar in appearance.
How long does cast iron deep half round guttering last?
Cast iron guttering, when correctly installed and regularly maintained with paint, typically lasts 50 to 100 years or more. This significantly exceeds the lifespan of uPVC alternatives and makes it the preferred choice for heritage and conservation projects.
