Description
The GHR1 is a 125mm half round aluminium gutter length, measuring 133mm x 56mm x 3 metres (3000mm) long. It is extruded from 6063-T6 hardened aluminium and polyester powder coated in Interpon D1036 architectural-grade powder. Straight, strong and corrosion-resistant, with a functional life of over 50 years. Manufactured in-house and supplied factory-direct.
Lightweight, rustproof and rot-proof, aluminium half round guttering is the low-maintenance alternative to cast iron and uPVC — it will not warp, split or require repainting, and the finish is fully over-paintable should you wish to change colour later. Ideal for efficient rainwater management on residential, heritage and commercial properties, and 100% recyclable at end of life.
This is a single 3 metre length. For the full system — jointers, angles, running outlets, stop ends, brackets and downpipes — see our aluminium half round gutters range.
Colour: stocked in RAL 7016 Anthracite Grey and Textured Black (5 working-day lead time). A wide range of non-stocked RAL colours is available to order on a 10 working-day lead time.

- 125mm half round profile — traditional appearance with high flow capacity

How many brackets do I need?
Fascia brackets are sold separately and fix at a maximum of 1 metre centres. As a guide, allow 3 brackets per 3 metre gutter length, plus one additional bracket for every running outlet, angle and stop end, positioning a bracket within 150mm of each of these fittings and of every joint. Reduce the spacing in areas exposed to high wind or heavy snow loading.
