Channel Drains
F900 Channel Drain
The heaviest class in EN 1433, rated for a 900 kN test load — for ports, docks and airport aprons.
F900 Channel
Ductile iron, EN 1433 F900
F900 is the top of the EN 1433 scale: a 900 kN test load, against the 400 kN of the D400 carriageway class. It is specified where the wheel loads stop being road traffic and start being plant — container handlers in a port, loading docks, aircraft aprons, heavy industrial yards. The extra capacity is in the casting rather than the fixings alone: a deeper section and a heavier grate, secured by eight M10 screws per unit instead of four.

Read from the factory drawing: grate width 205 mm, overall depth 230 mm, channel depth 210 mm, weight 54 kg. The clear waterway and the unit length are not dimensioned on that drawing and are not published until the foundry confirms them — do not assume they match the D400 channel of the same nominal size, which is a different casting. The rest of the F900 range is in preparation. Full drawings and DWG files are available on request.
Common questions
Specifying channel drains
- When do I need F900 rather than D400?
- When the load stops being road traffic. D400 is the carriageway class at a 400 kN test load; F900 is 900 kN, and is specified for container handling areas, dock aprons, aircraft stands and heavy industrial yards where point loads from plant far exceed anything a lorry applies.
- Is it the same channel as your D400 range in a heavier class?
- No. It shares the 200 body section — the same 205 mm grate width and 210 mm channel depth — but the grate is a different casting, deeper overall and secured by eight M10 screws instead of four M8. They are not interchangeable.
- What is cast into the grate?
- FDG DRAIN 200, the EN 1433 class marking KL F 900, and the CE mark, all cast into the face rather than applied afterwards.
- Are the other sizes available in F900?
- The range is in preparation. Send us the flow and the loading for your project and we will confirm what is available against your programme.
