Ductile Iron Set & Single Grating
Ductile iron drainage grating supplied as a single grating or as a set (grating plus frame), rated up to D400 per BS EN124-2:2015. The grating disperses wheel load into the road structure to protect the surrounding asphalt from settlement; a sprung, hinged bar locks it to the frame against rattle and theft, with cross-ribbed anti-slip bars and uninterrupted slots for high water intake.
