Zambelli galvanised steel downpipes are the perfect way to finish off your metal rainwater project. We sell the downpipes in 60mm, 80mm or 100mm sizes.
Designed in Germany and trusted across the UK, they are designed to far outlast plastic or cast-iron style alternatives.
If you’re looking for a durable, low-maintenance solution that complements your galvanised guttering, this system delivers in every way.
Exceptional Durability in All UK Weather
Made from high-quality galvanised steel, these downpipes are built to handle the unpredictable British climate.
From heavy rain and high winds to snow and frost, they won’t warp, crack or become brittle like cheaper plastic pipes. They are also easy to install and come with all the guides needed to complete your project.
Each downpipe features Zambelli’s advanced zinc-magnesium coating, which protects against corrosion and maintains a flawless finish for decades. The result? A system that performs year-round and keeps your property looking smart.
Corrosion & Fire Resistant for Total Peace of Mind
Galvanised steel downpipes are built to stand the test of time. Each one is protected by a clever layer of zinc that acts like armour against rust, peeling, and everyday wear. Rain, frost, or salty seaside air — they just shrug it off.
Because of that tough galvanised coating, you won’t need to worry about constant upkeep or repainting. Unlike copper or iron, which can tarnish and corrode, these downpipes stay strong and good-looking for years with barely any maintenance.
And it’s not just about the weather — steel is naturally fire-resistant, too. In the unlikely event of a blaze, it won’t melt or spread flames. That makes it a smart, reliable choice for homes in the countryside or wooded areas where extra safety matters.
In short: you fit it once, and it just keeps doing its job — quietly, safely, and beautifully.

A Sustainable, Eco-Friendly Choice
Choosing galvanised steel downpipes isn’t just a practical decision — it’s an environmentally responsible one.
Steel is one of the most recycled materials in the world, with a recycling rate of over 90%.
That means at the end of their long lifespan, your downpipes can be completely reused, reducing waste and conserving resources.
When paired with the galvanised guttering you get a sustainable, closed-loop rainwater system that’s built for the future.
Easy Installation & Seamless Design
Zambelli’s engineering precision ensures a perfect fit every time.
The system’s swaged push-fit design makes installation quick and hassle-free, while the smooth, consistent surface finish offers a clean, modern appearance.
