Steel Downpipes

Steel & Galvanised Steel Downpipes

Steel downpipes are a vital part of any rainwater system, directing water safely from your gutters to ground level. By preventing water from pooling around walls and foundations, steel downpipes protect your property from damp and any costly structural damage. At Steel Superstore, we stock high-quality galvanised and painted steel downpipes. We also stock copper options, designed to last for decades while maintaining a sleek, modern appearance.

Our steel rainwater systems combine performance, durability and style, all with fast delivery across the UK. Our 87mm downpipes are perfect for residential homes and our 100mm downpipes prove popular for commercial buildings or large residential properties.

Why Choose Steel Downpipes?

Durability & Strength

Unlike plastic downpipes, steel downpipes can withstand harsh weather conditions, heavy rainfall and extreme temperatures without cracking or warping. With protective coatings and galvanised finishes, our steel rainwater pipes can last up to 60 years.

• Copper downpipes – premium 99% pure copper available on request

Easy Installation

Steel Downpipe Sizes

We supply the two most popular downpipe sizes in the UK:

Both sizes pair perfectly with our half round steel gutters in 125mm and 150mm sizes.

Steel Downpipes vs Other Guttering Materials

Steel vs Plastic Downpipes

Plastic downpipes may be cheap upfront but they fade, crack and require frequent replacement. Steel downpipes last decades and are resistant to UV damage and temperature changes, making them the cost-effective solution in the long-term.

Steel vs Cast Iron Downpipes

Cast iron is strong but heavy and harder to install. Steel offers similar durability while being much lighter, easier to fit and lower maintenance.
