Lindab Magestic Galvanised 150mm Half Round Steel Gutter Outlet (75mm)

Connect high-capacity eaves to your drop with the Lindab Magestic Galvanised 150mm Half Round Steel Gutter Outlet (75mm). Engineered for flexibility on site, this running outlet can be positioned anywhere along the gutter—simply cut the aperture and click-fit the outlet for a fast, sealant-free installation. Built from zinc–magnesium enhanced galvanised steel, Lindab’s Magestic coating stabilises the surface and protects zinc’s naturally porous structure, delivering excellent resistance to red rust and white staining with minimal upkeep, even in exposed or coastal locations. The crisp galvanised finish weathers to a smart dark grey patina over time and pairs cleanly with both heritage and contemporary façades. Designed to transition from 150 mm half round gutter to a 75 mm downpipe, it integrates seamlessly with Magestic brackets, unions and steel drops for reliable, high-capacity drainage. Choose Magestic when you want strength, clean lines and installer-friendly detailing across demanding UK projects.
