Alumasc Water Management Solutions - Harmer Steel Rainwater Systems

Alumasc Steel is a lightweight range of contemporary, eco-friendly and cost effective alternative to plastic gutters, without the risk of shrinking, leaking or colour fading. The gutter is available in a choice of four widths in the popular Half Round profile along with a connecting round downpipe system.


  • Ideal for traditional and modern buildings in both new build and refurbishment applications
  • A competitive alternative to uPVC systems, with increased flow rates and longevity

Features & Performance

  • All gutter widths are deep half round providing maximum flow rates
  • Higher flow capacity on outlets due to larger inlet funnels
  • Gutter angle is ‘deep drawn’ and one piece giving greater flow capacity
  • Lightweight, durable and non-corrodible
  • Quick and easy installation
  • Fascia bracket has a larger back plate for installation ease and 6 fixing points compared to 2 on other systems
  • Internally seamed downpipe gives a smooth and modern finish
  • Downpipe brackets have two concealed vertical fixing points
  • Low maintenance

Colours & Finishes

  • Available in steel in either a Galvanised or Black Pre-coated finish
  • Also available to order in 6 other galvanised pre-coated colour finishes upon request
  • The system is also available to order in plain zinc or copper
  • All colour coated lengths are protected with an adhesive film to prevent damage on-site

Installation & Fixing

  • Dry joint system without the need for additional silicone sealants
  • Gutter lengths and angles are jointed with ‘EPDM rubber sealed’ connectors for fast and watertight installation
  • Downpipes and offsets are push fit with ‘Swaged’ ends, again for fast and watertight installation
  • Stop ends are push-fit with ‘EPDM rubber sealed’ inserts
  • Fascia brackets have wide back plates and are multi holed for fast and ultra-secure fascia fixing
