D400 Ductile Iron Circular Manhole Cover | Adjustable Subsidence-Prevention Inspection Manhole Cover (diameter 780)
This adjustable subsidence-prevention ductile iron circular manhole cover is ideal for urban roads, motorways, parking lots, municipal pipe networks, and various heavy-duty traffic areas. Manufactured from ductile iron, it offers excellent load-bearing capacity, impact resistance, and durability. The height can be adjusted according to pavement elevations, effectively reducing elevation differences between the cover and the road surface, while minimizing subsidence, vehicle bumping, and looseness.
