|CAST IRON||DUCTILE IRON|
|Impact resistance is poor. Under severe impact it will break.||Strong impact resistance. Under sevre impact it will bend.|
|Due to lower strength, weight of the manhole covers will be more for a specfic duty.||Due to high strength, weight of the manhole covers will be less (Min. 2/3rd) by weight.|
|Due to higher weight handling will be difficult.||Dut to low weight transportation, handling, installation and inspection is easy.|
|Poor capability of vibration absorption.||High capability of vibration absorption.|
