One of the primary materials used for manufacturing 600 x 500 manhole covers is cast iron, known for its durability and strength. These covers must withstand the heavy loads of traffic while maintaining their structural integrity. Advanced manufacturing techniques, including ductile iron and composite materials, are also making their way into the market. These innovations contribute to a reduction in weight while enhancing resistance to corrosion, therefore extending the lifespan of the covers.

However, the square manhole cover does come with its own set of challenges. Theoretically, if a square cover is positioned diagonally over the hole, it could fall through. This poses a risk that is inherently absent with round covers. Thus, the use of square manhole covers can be seen as a compromise—acknowledging both aesthetic and practical concerns while also embracing the complexities of urban infrastructure.
