Key Specifications/Special Features:

Manhole covers are often made out of cast iron, concrete or a combination of the two. This makes them inexpensive, strong, and heavy, usually weighing more than 50 kilograms (110 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorised people without suitable tools to remove them.
Manhole covers have different weight classes depending on their application. For example, a Class A15 (cast iron) manhole cover can withstand a maximum weight of 1.5 tonnes. It would typically be restricted to light duty applications, such as in pedestrian areas, gardens, patios and driveways; whereas a F900 class manhole cover would typically be used in docks, airports and other extreme heavy-duty applications.
Manhole covers may also be made from glass-reinforced plastic or other composite material (especially in Europe, or where cover theft is of concern). Because of law restricting acceptable manual handling weights, Europe has seen a move towards lighter weight composite manhole cover materials, which also have the benefits of greater slip resistance and electrical insulating properties.
A manhole cover sits on a metal base, with a smaller inset rim which fits the cover. The base and cover are sometimes called "castings", because they are usually made by a casting process, typically sand-casting techniques.
