Benefits of Cast iron Downpipes

Cast iron downpipes are not as common as they once were because cheaper alternatives have replaced them. However, that doesn't take away from the benefits of having cast iron guttering products. While you may find cheaper options, cast iron downpipes are tested. They have excellent advantages, which is why they have remained relevant after so many years.


Cast iron downpipes are incredibly strong and don't deflect or sag under load. They are perfect for homes in areas with heavy rainfall and snow, and they also make maintenance easier because you don't have to worry about the positioning of the ladder.


Cast iron downpipes are sturdy and easily handle the challenges of site handling. The pipes have a low coefficient of expansion and contraction; therefore, they don't need an expansion joint.

Cast iron has high resistance to impact, making the downpipes perfect for busy areas like car parks and schools where the exposed pipework is exposed to damage or vandalism.


Cast iron downpipes have an extensive lifespan. The pipes will easily last between 70 and 100 years with adequate maintenance. The downpipes will easily withstand the challenges of mechanical unblocking and maintenance.

The pipes do not warp or fade in the sun. Our range has pipes finished in a protective primer and a high-specification wet paint coating for enhanced performance when exposed to aggressive substances or environments.

Fire resistant

Cast iron is non-combustible. This unique quality makes it ideal for use in public buildings like hospitals and schools. In case of a fire, the pipes will not contribute to spreading the flames. They will not melt or drip, and they will not emit toxic fumes.


Cast iron downpipes benefit your pockets, property and the environment. They have a low carbon footprint impact because they are 100% recyclable and do not add harmful chemicals to the water or the soil where the water drains.


Cast iron downpipes have been in use since the 15th-century. We supply cast iron downpipes made using traditional casting styles and die-casts that stay true to the historical styles and preserve the original aesthetics of the pipes and the buildings in which they are installed.

Our cast iron downpipes are perfect for listed buildings requiring genuine pipes that will retain the original strength, character, and integrity of the original rainwater system.


We go a step further and offer a range of customisable solutions for your clients looking for unique details, designs and lengths and sizes in cast iron pipes. We work with leading foundries with the right experience to guarantee exceptional performance and match the specifications of your projects.
