A manhole cover is used to cover wells on roads or in deep wells at home, preventing people or objects from falling. By material, it can be divided into metal manhole covers, high-strength fiber cement concrete manhole covers, resin manhole covers and others. Generally round, they can be used in green belts, sidewalks, motorways, docks and alleys.

Resin manhole covers feature light weight and high strength, excellent fatigue resistance, damage safety, simple molding, low noise under vehicles, good chemical and acid/alkali corrosion resistance and beautiful appearance. Their overall performance has surpassed cast iron covers.

Ductile iron manhole covers are a type of ductile iron product. Through spheroidization and inoculation treatment, spherical graphite is obtained, effectively improving the mechanical properties of cast iron, especially its plasticity and toughness, resulting in higher strength than carbon steel.
