Round tubes are the strongest and most material-efficient shape against the compression of the earth around them. A round manhole cover of a given diameter has a smaller surface area than a square cover of the same width, thus less material is needed to cast the manhole cover, meaning lower cost.

The bearing surfaces of manhole frames and covers are machined to assure flatness and prevent them from becoming dislodged by traffic. Round castings are much easier to machine using a lathe. Circular covers do not need to be rotated to align with the manhole.

Rectangular Manhole Covers are widely suited for covering manholes on the streets and roads, this range can shield manholes correctly and rigidly, preventing serious mishaps. These products have comparatively low prices, but are specifically designed to ensure long-term performance.

Overall, ductile iron manhole covers are preferred over other materials due to their strength, durability, and corrosion resistance. They are designed to withstand heavy loads, making them suitable for use in high traffic areas such as roads, highways, and airports.

As the FRP Manhole Covers are flexible and do not disintegrate into pieces due to excess load bearing imparted on the cover , accidents on roads are avoided as the chambers are not left open even in case of cracking of cover.
