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 113 kilograms (249 lb). The weight helps to keep them in place when traffic passes over them, and makes it difficult for unauthorized people without suitable tools to remove them.

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.

Other manhole shapes can be found, usually squares or rectangles. For example, in the United Kingdom nearly all manhole covers are square or rectangular and very occasionally triangular, but almost never circular. Nashua, New Hampshire, is unusual for having triangular manhole covers that point in the direction of the underlying flow. In 2011, the city began gradually phasing out the triangles, which were made by a local foundry, because they were not large enough to meet modern safety standards and a manufacturer for larger triangles could not be found. Some manhole covers in Hamilton, Bermuda, are triangular, and hinged. Some triangular water-main covers also exist in San Francisco

Product Characteristics

1. Strong load-bearing capacity
The square cast iron has a very strong load-bearing capacity and can withstand the pressure of heavy objects such as vehicles and pedestrians. This is very important because the city is densely populated with people and vehicles, and the manhole cover is easily under pressure. The square cast iron manhole cover is made of solid materials and has a strong guarantee in load-bearing capacity.

2. Strong durability
The square cast iron manhole cover is made through multiple processes and has high durability. It can withstand the erosion of various natural environments such as natural wind, sun, rain, etc. Therefore, the square cast iron manhole cover has a good performance in terms of service life and is relatively economical and practical.

3. High safety
During the production process, the square cast iron manhole cover uses solid materials and precise processing technology, so it can ensure safety in different environments. At the same time, the surface of the square cast iron manhole cover adopts an anti-slip design, which makes it have good anti-slip performance in a humid environment and prevents pedestrians from slipping on rainy days.

The covers usually feature "pick holes", into which a hook handle tool is inserted to lift them. Pick holes can be concealed for a more watertight lid, or can allow light to shine through. A manhole pick or hook is typically used to lift them, though other tools can be used as well, including electromagnets.
