Lindab Rainline is a Swedish galvanised steel guttering system and a popular alternative to PVC, aluminium and cast iron. It is strong, fully recyclable and comes in a wide range of colours. This guide covers how to choose the right size, profile and finish.
1. Choose a profile
- Half round – the classic profile for most houses, extensions and outbuildings. Gutters come in 100mm, 125mm and 150mm. Lindab half round gutter
- Rectangular (140mm) – a crisp, contemporary box profile for modern builds. Lindab rectangle gutter
2. Choose a size
As a rule of thumb, larger and steeper roofs need bigger gutters and downpipes:
- 100mm gutter – small roofs such as porches, sheds and garden rooms.
- 125mm gutter – the usual choice for houses and extensions.
- 150mm gutter – large or steep roofs and commercial buildings.
Downpipes come in 75mm, 87mm and 100mm. More downpipes, or larger ones, increase capacity. For large roofs, check Lindab's capacity tables or ask us to size it for you.
3. Choose a finish
- Magestic galvanised – a bare metallic finish with Lindab's highest surface protection. 10 year warranty.
- Colour coated (high-build polyester) – including Black, Anthracite Grey, Anthracite Metallic, Silver Metallic, White, Dark Grey, Matte Black and Matte Anthracite Grey. 15 year warranty.
See our Lindab warranty page for details.
4. Choose brackets
- Fascia brackets – screw to the fascia board; the most common fixing.
- Rafter brackets – fix to the rafters before the roof is covered. Use them where there is no fascia board, or for a cleaner eaves line. Side-fix versions are available.
5. Build your order
A typical run needs gutter lengths, joints, stop ends, an outlet, angles at corners, brackets, downpipe lengths, bends (offsets), downpipe brackets and a shoe or drain connector. Our Lindab Quick Order page lists every part by size and colour so you can order a complete system in one go.
