BS En 124 Lockable ductile iron manhole covers for road drainage Sewer covers with frames

Ductile iron manhole covers are a common road feature used to cover the wellhead or manhole below, protect equipment and pipes in the well, and provide a flat surface for pedestrian and vehicle traffic. The following is an introduction to ductile iron manhole covers:

Material: Ductile iron manhole covers are made of ductile iron (also known as ductile iron), a special cast iron material that is given higher strength and corrosion resistance by adding magnesium and other alloying elements during the casting process.

Structure: ductile iron manhole covers are usually composed of cover plates and frames. The cover plate is flat and is used to close the wellhead or manhole, while the frame is used to secure and support the cover plate and is chimed into the road surface.

Features: ductile iron manhole cover has the characteristics of high strength, corrosion resistance, wear resistance and pressure resistance. They can withstand the load of vehicles and pedestrians and have a long service life.

Safety: Ductile iron manhole covers usually have a non-slip texture or non-slip coating to provide good walking safety. They also prevent accidents, such as pedestrians or vehicles falling into Wells.

Application: ductile iron manhole covers are widely used in roads, sidewalks, parking lots, squares and other public areas. They can also be used for wellhead coverage of industrial facilities, water supply, drainage, power, communications and other infrastructure.
