Cast Iron Gully Gratings
Single gratings and multi-unit sets for kerb inlets, carriageways and yards — cast in ductile iron so the bars resist impact instead of snapping.

Single Gully Gratings
One grating, one frame. Used where the inlet opening is a single unit — residential kerbs, car parks, yard drainage and smaller catchpits. Bars are tapered so debris washes through instead of wedging between them.
- Slotted (bar) or round-perforated patterns
- 300×500 up to 500×750 mm
- A15 to D400 depending on location
- Hinged version for single-person lifting
- Waterway area up to [1,100] cm²

Slotted or perforated?
Slotted gratings pass water faster per unit area and are the standard for road gullies. Perforated gratings handle litter better and are common in parks, yards and food-processing areas where solids must not fall through.

Installation
Fitting a Grating So It Stays Quiet
- Bed the frame on mortar, not on rubble.A frame sitting on loose spoil rocks under traffic and cracks at the corners.
- Keep the frame flush with the channel, not proud of it.A lip of 3–5 mm is enough to catch a snow plough or a bike wheel.
- Match the class to the traffic, not to the price.A B125 grating in a delivery yard will deform within a season.
- Leave the lifting key with the client.Gratings lifted by crowbar chip the edge and ruin the coating.
