Introducing our Ductile Iron Round Manhole Cover, designed for optimal strength, durability, and performance in high-traffic areas. With a specific focus on providing maximum resistance to impact and deformation, our round manhole covers integrate advanced ductile iron material to ensure they withstand substantial weight loads and rigorous conditions. The circular design offers significant advantages over traditional shapes and aligns with the engineering best practices for sewer alignments, ensuring a maximum spacing of 600 ft for straight lines and 400 ft for curvilinear alignments. Furthermore, these covers guarantee a minimum of five feet horizontal clearance between adjacent manholes to promote safety and accessibility. Ideal for urban infrastructure and industrial applications, our manhole covers are compliant with the latest quality and engineering standards, catering to the needs for both durability and functional integrity. Choose our Ductile Iron Round Manhole Cover for a long-lasting solution that delivers superior performance and reliability while meeting stringent regulatory conditions.

The maximum spacing for manholes on straight sewer alignments is 600 ft. (182.9 m). If the sewer is constructed on a curvilinear alignment, the maximum spacing between manholes shall be 400 ft.It has been proved beyond reasonable doubt that circular sewer covers offer the maximum strength, resistance and durability – and that's precisely why every top manhole cover manufacturer focuses on designing round manhole covers, made of best-in-class material and in compliance with all the latest quality parameters.
Minimum Spacing Between Manholes. 1) Outside diameter (OD) of adjacent manholes (including the bottom slabs) should have minimum of five (5) feet horizontal clearance.Small PPIC (polypropylene inspection chamber) up to 300mm diameter are generally only allowed to go to a depth of 600mm (0.6m) due to the narrow width of the chamber. These can be used in areas close to a house and near to the top of a drain.Ductile iron manhole covers are stronger than cast iron. Hence, it can endure heavy weight better in high-traffic areas. Ductile iron covers are flexible due to their ductile characteristics, which is why, they can bend without breaking or cracking
