    I'm a long-term partner of this factory. I've been on a field trip.The factory is strong and the grating quality is very good. I cooperated with this grating supplier in 2017.What surprised me was that this factory was very strong,and it was also one of the top local grating factories.

Product Description

Cast Iron Manhole Cover and Frame 600L x 600W x 44H - B125 Class


Manhole covers are made of cast iron. These covers need to be heavy so that when vehicles drive over them, they do not become dislodged. Manhole covers normally weigh 100+ pounds each.


Some have open pick holes which allow water to enter the manhole. Others have concealed pick holes which do not go all the way through the cover or lift handles such as drop handles or ring handles.


Manhole covers can be bolted to the frame for security reasons. Manhole covers can also have a gasket on the bottom of the cover and bolted to the frame which is normally considered watertight.


Cast Iron Double Triangular Manhole Cover and Frame

Features : Inverted vee seatings combine with three point suspension to
provide cover stability under load and to discourage abrasive
material from becoming trapped under the bearing points.

Functions : Designated to be used in Government roadway drainage projects
and maintenance projects.

Applications : For Storm Water (with circumscribed raised stubs on the cover)
For Foul Water (with rectangular raised stubs on the cover)

Manhole covers provide entry to an underground world of sewers, water mains, power/communication lines, conduits, etc.

Manhole covers are a form of art. They are normally lettered ‘Sanitary Sewer’ or ‘Storm Sewer’ but can basically be lettered anything. Manhole covers have different patterns/designs on them and even custom logos if a city desires. Look down next time you are walking through a city and take note.
