What are the benefits of steel gutters for commercial builds?
A high-strength, lightweight rainwater system made from galvanised or coated steel, designed for long service life with minimal upkeep.
Why choose steel over aluminium or cast iron?
It offers excellent strength-to-weight ratio, good recyclability and a clean contemporary look at a lower cost than copper or zinc.
What finishes are available?
Pre-coated galvanised steel in natural metallic, anthracite or coloured polyester finishes to match building façades or roofing systems.
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.
