What Are Manhole Covers Made of & What Materials Are Best?

When choosing the suitable material for your manhole cover project, you may be wondering: what are manhole covers made of, and what is the best material?

It’s essential to consider the load rating of the cover. Depending on the installation location and requirements, the appropriate material may be light-duty or heavy-duty.

MCD’s Standard Materials for Covers and Frames

Below are the materials available for our manhole covers and frames:

  • Steel: ASTM A36 hot rolled carbon steel is a common structural steel alloy utilized in the United States and is our standard. Ask about other grades of steel if required.
  • Stainless Steel: 304 stainless steel is the most common stainless steel and is our standard. Ask about other grades of stainless steel, such as 316L, if required.
  • Aluminum: 6061 T6 aluminum is a precipitation-hard­ened aluminum alloy and is our standard. Ask about other grades of aluminum if required.
  • Composite: Our closed mold injection systems produce durable and lightweight covers that are H-20 load rated. Composite covers are fiberglass reinforced with polyester resin.
