Cast iron downpipes are ideal for heritage and listed properties. They are also an excellent choice for restoration work in conservation areas. After centuries of use with amazing durability and strength, it’s evident that you can never go wrong with cast iron downpipes.

At Cast Iron Superstore, we have a full range of cast iron downpipes in various configurations. Whether you’re working on a Victorian-era project or a modern property, we have unique cast iron downpipes that will fit right in with your current project.

Profiles, Dimensions and Sizes

We stock cast iron downpipes from the most reputable foundries like Britannia. The downpipes are made from traditional die casts, making them stand out in heritage or listed projects. You can choose from various options available depending on your needs and preferences.

Profiles

The cast iron downpipes come in two primary profiles:

Round

Our round cast iron downpipes range comes in various sizes, lengths, and finishes. You can find the pipes in sizes 2.5," 3," and 4." We can supply the pipes in lengths of up to three metres depending on the requirements of the projects.

Standard finishes for the round cast iron downpipes include grey primed, delivered ready for on-site painting, and a semi-gloss, black, high-quality factory finish. We can also deliver the pipes in a selected range of colours.

Rectangle

Under the rectangle profile, we have rectangular and square profile downpipes. They come in the 4" x 3" configuration, perfect for most applications. Like the circular downpipes, we can deliver this profile in an in-transit grey, primed finish which is perfect for painting on-site, and we can also deliver it in our standard semi-gloss black finish. We also custom finish options upon request for our clients.

If you can’t find the type of cast iron downpipe you want within our range, don’t hesitate to contact us and enquire.

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.

Strong

The downpipes are incredibly strong. They 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.

Diverse

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.

Durable

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 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 the spreading of the flames. They will not melt or drip, and they will not emit toxic fumes.

Sustainable

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

Authentic

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 system's strength, character, and integrity.

Bespoke

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.
