For intricate castings with delicate designs, finishing is an important process, however; cast iron manhole covers do not require excess finishing except removing the frames, runners and risers. The bearing surfaces can be shot-blasted and machined to ensure that it lies flat in the frame.
Uses of Manhole Covers
Manhole covers are used wherever there is a manhole, simply because the hole needs to be covered up to prevent accidents and to protect the public from harmful gasses, fumes, heat, high voltage and explosions. Cast iron manhole covers are preferred because they are heavy duty, strong, long lasting and are not dislodged easily. Plain and decorative manhole covers are used depending on where they are to be installed. Manhole covers are commonly known to be used to cover manholes for water drains, sewer drains, electric cable trenches and telecommunication lines. They can also be used as decorative additions to driveways, yards and walkways. Manhole covers are also used for industrial application such as for storage tanks and silos, surge tanks, for road tankers carrying petroleum and acid, pressure vessels etc.

Structural Considerations
It will be done by raising the cover slightly in a vertical direction then withdrawing it at low level. Using rollers, it will be move to a space, not close yet not far from the whole.
Additionally, tree well grates play a crucial role in urban safety. They help to minimize tripping hazards by maintaining an even surface around tree installations. Without these grates, uneven ground can pose a danger to pedestrians, particularly in high foot-traffic areas. By providing a stable, flat surface, tree well grates contribute to a safer walking environment, benefitting individuals of all ages, including the elderly and those with mobility issues.
