Material: Ductile Iron. Ductile cast iron is made by adding nodularizing agent to cast iron and undergoing nodularization and high temperature treatment. It has good corrosion resistance, high strength and high toughness, making it durable in various environmental conditions.

Bearing class: F900. This means that the manhole cover can withstand loads of up to 900kN, making it ideal for use where extremely high load-bearing capacity is required, such as airports or other places with high static and dynamic loads.

Executive standard: Comply with EN124 standard. EN124 is the European standard for manhole covers, which specifies the design requirements, materials, manufacturing processes and performance tests of manhole covers. Manhole covers that meet this standard are designed for reliability and durability.

Anti-settlement: Ductile iron manhole cover adopts special structure and material design, which can effectively prevent the sinking and loosening of the manhole cover, and ensure the stability during use.

Quiet: Ductile iron manhole covers can effectively reduce the noise and vibration generated by vehicles and pedestrians through the use of shock-absorbing materials or special designs, and provide a quieter use environment.
