Common questions
Specifying channel drains
- How do I choose the width?
- By the flow the run has to carry and the channel it seats in. The three widths give clear waterways of 140.5, 190 and 240 mm — that figure, not the nominal size, is what governs capacity.
- What does reinforced mean?
- Additional and heavier ribs beneath the bearing surface. Only the reinforced castings are supplied.
- What load class are they?
- EN 124 D400 throughout, the carriageway class rated for a 40 tonne test load, cast into the face of every unit.
- How long is each unit?
- 750 mm, laid end to end along the run.
