Lindab Magestic Galvanised 150mm Half Round Steel Gutter Union

Make long, high-capacity runs quick to assemble with the Lindab Magestic Galvanised 150mm Half Round Steel Gutter Union. Using Lindab’s click-and-lock mechanism with an integrated rubber seal, this joint creates a neat, watertight connection without sealant or screws—ideal for speeding up installs and keeping façades clean. Use it to couple gutter-to-gutter lengths or to connect straight sections into internal/external angles on large roof areas where flow and alignment matter. Part of the Magestic range, the steel is enhanced with magnesium to stabilise the galvanised layer and protect zinc’s naturally porous structure, delivering excellent resistance to red rust and white staining with minimal upkeep, even on exposed or coastal sites. The unpainted galvanised finish complements both contemporary cladding and heritage brickwork and will weather to an attractive dark-grey patina over time. Pair with Lindab Magestic 150 mm brackets, outlets and matching downpipes for a cohesive, recyclable system built for UK conditions.
