Ductile Iron Round Manhole Cover D400
Round ductile iron manhole cover and frame rated D400 per BS EN124-2:2015, cast in GGG500-7 for municipal road carriageways. The round plate carries load with balanced stress for lower noise, seats without rocking under traffic, and cannot fall through the frame — a durable, anti-theft, anti-rust cover with a hinged, self-sealing seating suited to Central Asian municipal roads.
