The ease of manufacturing and installation plays a vital role in the choice of a round shape as well. Circular covers are easier to produce and can be uniformly shaped by molding processes. This uniformity allows for mass production, resulting in cost savings for municipalities and utility companies. Additionally, round covers can be easily rolled and moved, which simplifies installation and maintenance tasks. Workers can handle them with less strain, further enhancing efficiency during service operations.
