Manholes are crucial in facilitating maintenance work for underground channels and passages. From city to suburban areas, manholes play an active role in ensuring the drainage system. To prioritize safety and security, manholes are not left open; instead, they are sealed or locked using covers.
These covers come in different variations, including solid round-top and square-top designs. Additionally, recessed manhole covers are gaining popularity in the industry as well.
Here, we focused on the key features of recessed manhole covers which lead the market forward.
Types Of Manhole Cover
It has been seen for a long time that manhole demand is growing in various applications and locations. The leading manhole cover manufacturers in India are producing a wide range of covers known for their durability and long-lasting properties. These covers come in several variations, with the most commonly used materials being cast iron, concrete, or a combination of both (hybrid).
Additionally, alternative materials are available for casting manhole covers, such as fiberglass, plastic, and composite materials.
According to the IS standard, there are three main types of manhole covers that are recognized and utilized in the industry.
