More about Alumasc Steel Box Guttering

Steel box guttering from Alumasc is created for modern buildings that require a clean linear edge and strong capacity for managing significant water volume. The squared profile works well with flat roofs and contemporary facades. Steel construction keeps weight manageable while providing solid resistance to weather exposure. This system supports fast installation and can be supplied in a variety of colours to align with architectural plans. Used with steel downpipes it helps deliver a dependable and neat drainage solution for a wide range of properties.

FAQ

Where is box guttering most suitable?

Commercial, industrial and flat-roof projects needing large capacity and linear fascia integration.

How are steel box gutters supported?

By hidden brackets or strap supports at close centres due to the larger water volume they carry.

What coating options exist for box gutters?

Polyester powder-coated, galvanised, or pre-weathered steel to match façade or roofing materials.

What’s the expected lifespan of Alumasc copper, zinc and steel rainwater systems?

Copper and zinc systems can last 80–100 years in the right environment, developing a natural patina that protects the metal. Galvanised or coated steel systems generally last 40–60 years depending on coating type, exposure and maintenance.

Do these materials require ongoing maintenance?

Minimal maintenance is needed. Periodic clearing of leaves and checking fixings is sufficient. The metals naturally form protective oxide layers or coatings, so repainting is not required unless specified.

Are Alumasc metal rainwater systems sustainable?

Yes. Copper, zinc and steel are all infinitely recyclable with minimal loss of quality. Alumasc sources responsibly produced metals with high recycled content and low embodied carbon.

How are joints sealed and connected?

Most systems use mechanical joints or sliding connections with EPDM or neoprene gaskets. Copper and zinc are usually jointed by soldering, standing seams or hidden clips, while steel systems use push-fit or bolted unions with gaskets.

Can different metals be mixed in the same installation?

Mixing dissimilar metals should be avoided due to galvanic corrosion risk. Always use separation layers, same-metal fittings, and compatible fasteners recommended by Alumasc.
