Ductile Iron Manhole Cover

Advantage of hinged manhole cover:

--Anti-theft

--Load-bearing great

--Corrosion resistant

--Opens conveniently

--Superior safety performance

Main Function:

It can be said that ductile iron manhole cover is the only medium connecting the ground and the ground, and it is also the main outlet for water discharge on the ground. In most cases, it plays a role in avoiding the falling phenomenon of road roadway and vehicles and pedestrians. Therefore, manhole cover has an extremely strong hardness and strength, and even can withstand the weight of dozens of tons of truck, which is more safe and efficient to ensure the travel safety of people and vehicles.
