More Information on Heavy Duty Manhole Covers

These are detachable plates that form a lid over the manhole. The main purpose of these covers is to avoid unauthorised access and to prevent anything from falling in the manhole. Typically, manhole covers will be found on paved driveways, pavements and roads to prevent any access to the underground system.

Heavy duty manhole lids come in different sizes and load ratings, and are made from either plastic, ductile iron, a composite material or galvanised steel.

The load ratings range from A15 (1.5 tonnes, usually made from plastic or galvanised steel), B125 (12.5 tonnes, usually made from composite), C250 (25 tonnes, usually made from composite), and D400 (40 tonnes, usually made from ductile iron). This is the strength the lid can withstand from passing traffic.

Recommended Locations for Placement

Ductile Iron

The lids with the heaviest load ratings are made from this material, which is the highest quality of cast iron. Here is a brief list of the advantages:

  • Reduces vibration
  • Tougher than white cast iron
  • Not easily broken or cracked
  • Can survive high loads


With regards to price, these covers are slightly more costly compared to medium duty covers. Considering that higher quality materials are required to manufacture them.


How to disguise drain covers?

These covers come in a wide range of styles and appearances. But they still stick out and are an eyesore in some areas.

While it isn’t a good idea to physically cover manhole lids, you can install recessed tray covers, which have many options of infill to hide and blend the cover.

How to fit a drain inspection cover?

Fixing new covers and frames onto a drain is an easy process so long as you use the right materials. It involves neatly removing the material (generally tarmac or concrete) around the old one, leveling and bedding the new frame in, back filling around it, and installing the cover.

How to raise a drain cover?

There are plenty of risers available in different sizes. Getting one to fit tightly may be tricky but a bit of sealant or cement should do the trick. You may be better off getting a new manhole cover with frame then joining that to your existing manhole. To lift the lid, you'll need a pair of heavy duty lifting keys.
