Hargreaves Halifax HD6071 150mm Cast Iron Grey Gully Inlet

The Halifax HD6071 forms part of the Halifax Drain range: a 150mm gully inlet, used to take surface water into a buried run.

Construction

• Material - Produced in grey cast iron under BS EN 877, with an epoxy finish averaging no less than 150 microns.
• Outlet - 150mm spigot outlet, connecting onward into the buried system using a standard Halifax coupling.
• Accessories - Accepts the matching Halifax plain grating or solid cover with seal and screws.

Ground movement

Cast iron expands by around 0.01mm per metre for every degree Celsius rise in temperature, a coefficient close to that of concrete and steel. In practice this means a buried Halifax run moves very little relative to the ground around it, unlike some plastic systems where thermal expansion can be five to twenty times greater.
