Additionally, the use of permeable manhole covers is being explored to improve urban drainage systems. These covers can allow rainwater to drain into the ground, reducing the risk of flooding during heavy downpours, thus contributing to more resilient urban infrastructure.

Grates are typically made from various materials, including cast iron, steel, and polymer. The choice of material can depend on several factors, such as location, expected load, and environmental conditions. Cast iron grates, for example, are robust and capable of withstanding heavy traffic loads, making them suitable for urban streets. In contrast, polymer grates offer lightweight and corrosion-resistant options, ideal for areas where weight and chemical exposure are concerns.

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.
