F900 Gully Gratings

F900 Gully Gratings & Frames

F900 ductile iron gully gratings and frames are certified to a 900 kN test load (90 tonnes) under BS EN 124-2:2015, the highest class in the standard. They are specified for airport aprons and taxiways, port operating areas and container yards, where aircraft wheels, straddle carriers and reach stackers impose very high point loads.

The Dover 450 x 450 grating sits in a 150 mm deep frame, cast in ductile iron to take sustained heavy loading without the brittleness of grey iron.

For help choosing a loading class, see our guide to BS EN 124 loading classes. For chamber access on the same pavement, see our F900 manhole covers and frames; for yards without aircraft or port plant, E600 gully gratings may be sufficient. Contact our Telford team for stock and lead times.

Add-A-Step Modular Ladder System
Add-A-Step Modular Ladder System Add-A-Step is a modular manhole ladder system that replaces traditional galvanised and stainless steel access ladders — at lower cost and with faster, safer installation. Fully compliant with BS EN 14396 and Sewers for Adoption 7th & 8th Edition, it’s approved for potable water, wastewater, highly corrosive and general construction environments, and is already the first-choice manhole ladder for several major UK water utilities. Because it’s modular, ladders can be built to exact chamber depths on site and individual components replaced without removing the whole ladder. R&B is the sole UK distributor — contact us for specification support or utility approval documentation.

Drain Defender - Gully Protection
Drain Defender - Gully Protection Drain Defender is a reusable gully protection insert that stops silt, sediment and construction debris entering the gully pot — protecting connected drains and sewers downstream. On developments with unmade roads, gullies quickly silt up, leading to blockages, flooding and costly cleansing before adoption. Drain Defender installs in seconds, is lifted out and emptied as needed, and dramatically reduces gully emptying and jetting costs across the life of a site. Proven on major housebuilder and civil engineering sites nationwide — see our case studies.

Duct Access Chambers
Duct Access Chambers Polypropylene duct access chambers developed with a UK manufacturer for power, telecoms, fibre and drainage networks. Lightweight sections make installation fast without lifting equipment, while the finished chamber withstands demanding highway and construction loadings. Available in a range of plan sizes and build heights to suit project specifications, and compatible with our ductile iron and fabricated cover ranges for a complete, single-source access solution. Used on schemes from urban infrastructure to major port developments.
