RoofArt 150mm Half Round Steel Galvanised Guttering

Designed for larger homes, commercial properties and barns, the RoofArt 150mm galvanised steel guttering system provides exceptional capacity and long-term reliability. Built with performance and durability in mind, this robust system handles higher flow rates with ease – even during heavy downpours or winter conditions.

Heavy-Duty Guttering for Larger Roofs

The 150mm half round profile is engineered for wider roof spans and high-volume drainage, making it the go-to choice for agricultural buildings, multi-storey homes and industrial units. Each component is made from 0.7mm Greencoat Prelaq steel with a hot-dip galvanised finish that’s resistant to corrosion, wear and UV exposure.

Installation is simple thanks to the system’s snap-fit design and bracket compatibility. The galvanised finish offers a clean, traditional look while keeping maintenance to a minimum. Backed by a 5-year warranty and an expected life of up to 50 years, this is a cost-effective rainwater solution built to perform in tough environments.
