Aluminium In Construction

The Guttermaster product and guttering services represents the highest possible standard in the design and manufacture of stylish aluminium guttering, rainwater pipes and fascia soffit systems.

Cast Half Round Guttering

The high capacity cast half round profile is cast from 3.0mm thick cast aluminium, producing an extremely strong, rigid gutter which far exceeds all the relevant British Standards. The hydraulic performance of the half round profile is advanced with its semi-circular sole and cast joint, allowing maximum unbroken flow. The cast process allows the use of the high strength 6063 T6 and permits gutters to be produced with the finest straightness tolerences available.


Different sizes are available:

  • High flow capacity.
  • Allows a reduction in the number of rainwater pipes.
  • All brackets have wind restraint lips to prevent uplift.
  • Joints incorporate spacers as part of the manufacturing process.¬† This ensures a 2mm sealant bed is maintained in the joint even if the bolts are over-tightened.¬† This allows the gutter to expand and contract freely without leakage.
  • The leg feature on brackets and union joints provides support in the severest of conditions, especially at joint positions.
