摘要
A cover for in-ground meter enclosures used in traffic loading conditions employs a relatively thin plate member formed of a ductile iron alloy and is dimensioned to extend laterally across a top opening of an in-around meter enclosure. A plurality of relatively thick rib members of the ductile iron alloy are formed with and extend generally normal from the bottom side of the plate member. The plate member and the rib members together have sufficient strength and ductility to withstand total loads on the order of at least about 20,000 pounds on the top side of the plate member.
