Description

Half round is the classic gutter profile for a reason: it self-cleans better than square profiles and suits everything from period brick terraces to new garden rooms.

In powder-coated aluminium, this 125mm system gives you that traditional look with a service life measured in decades — no fading, no brittleness, no sagging between brackets.

Every component is available individually, so you buy exactly what your run needs.

  • 125mm half round profile, powder-coated aluminium, 3m gutter lengths
  • Full fittings range: jointers, three bracket types, 90° and 135° angles, 63mm and 76mm outlets, stop ends
  • Textured Black or Anthracite Grey (RAL 7016)

Frequently asked questions

Which bracket do I need? Fascia brackets screw to a vertical fascia board — the most common fixing.

Side and top rafter brackets fix directly to the rafters where there's no fascia, common on older or agricultural buildings.

How many brackets? Space brackets at roughly 500–800mm centres, with one close to each joint, angle and outlet.

What do I need for a straight run? Gutter lengths to cover the run, one jointer per join, a stop end for each closed end, one outlet per downpipe, and brackets at the spacing above.

Will it match modern uPVC downpipes? The 63mm outlet suits standard 63mm round downpipe; the 76mm outlet suits larger 76mm systems.

After a contemporary square profile instead? See our Aluminium Box Gutter System. Lining an existing failing gutter? Our EPDM gutter lining kit waterproofs concrete, metal and timber gutters in place.

Complete the run with our matching Aluminium Downpipe System in 63mm and 76mm. If your conservation officer requires genuine cast iron rather than a lookalike, see our cast iron guttering & downpipe system.
