Britannia 5" Cast Iron Half Round Guttering FAQs

Britannia cast iron gutters are manufactured using traditional sand casting techniques, replicating historic profiles. Compliant with BS460:1964, they are approved for use on listed buildings and conservation areas, ensuring architectural authenticity.

Britannia 5 inch gutters are available transit primed (ready for on-site painting) or factory pre-painted in semi-gloss black. Other RAL and BS colour options can be ordered for a custom finish, though this may affect lead time.

A complete range of matching accessories is available, including fascia brackets, outlets, stopends, running outlets, unions, and corners. We also offer true radius gutters for curved sections.

The 5 inch guttering should be fitted on brackets at 915mm centres, with additional support for running outlets and angles (no more than 300mm from the joint). Expansion gaps of 3-4mm should be left at each socket, with joints sealed using a Britannia gutter jointing kit or Dow Corning 791 Sealant.

Minimal maintenance is required. Occasional cleaning and repainting will protect against rust and ensure decades of reliable performance. Regular inspections will keep the system functioning efficiently.

Yes! While the 5 inch gutters are designed for heritage and conservation properties, Britannia cast iron guttering also adds a timeless, high-quality finish to traditional-style new builds. Its strength, durability, and classic aesthetic make it a popular choice for a wide range of projects.
