The advantageous of round ductile iron manhole cover, is it will not full easily. Because the diameter of manhole cover is bigger than clearing open of manhole. In any position, it will not fall.
But, if it`s a square manhole cover, if the manhole cover turn 45 degree it maybe fall into manhole, because diagonal length is longer than side length.
The other advantageous of round manhole cover is easy carry, because it`s round, it can be rolled on the road so easy to transport.
