Alternative Gutter Profiles
  • Alumasc’s history of designing and supplying engineered rainwater systems is a sign of its ability to develop patterns for the sand casting of products that are tailored to individual buildings’ specific needs.
  • Whether the aim is to match an existing profile or simply to differentiate a building’s appearance, Alumasc can offer bespoke gutter profiles to suit.
Radiused Gutter Sections
  • Where gutters are required to follow a particular roof radius, patterns can be engineered from dimensions or existing gutter installations to yield a gutter that can be installed to suit the roof parameters.
Bespoke Gutter Brackets
  • Whether you are looking for a rise and fall style bracket or a decorative fascia bracket, Alumasc is able to manufacture non-standard brackets from cast iron or galvanised steel.
Pipe earbelts & holderbats
  • Ornate holderbats and earbelts can be detailed to provide a unique, distinguished appearance to a rainwater stack.

  • Wet sealed and bolted joints - a simple, well proven method
