In 2017, ductile iron manhole cover manufacturers reached a new peak of significant growth.

The new type of ductile iron manhole cover is made from QT500-7 ductile iron material, significantly enhancing product density. This results in exceptional performance characteristics, including high resistance to compression, bending, and impact, as well as excellent tolerance to heat, cold, wear, acids, alkalis, aging, and minimal deformation. Additionally, the refined casting process ensures crisp, well-defined surface textures, while the manhole cover features a distinctive anti-slip pattern that boosts friction—effectively preventing pedestrians from slipping on surfaces covered by rain, snow, or ice.
