Hull Sacrificial Anode

Sacrificial anode is a protecting cathode unit for metal constructions in marine and harbor industries.its properties are in compliance with the requirement of the GB/T 4950-2002. ZAC and AZI corrosion-proof sacrificial anode are synthesized mainly by high-purity (99.998%min) Zinc and fine Aluminum.Cadmium and lndium elements.They are the idea special corrosion-proof materials for protecting steel like matter when used under sea and ground ,ZAC is one of the outstanding cacrificial anodes. This product has been approved by China Vessel Inspection Bureau , Its quality specification meets the standard of GB4905-85,GB4948-85. Application Scope Ship Offshore engineering Dock and harbor Structure.Landing facilities used underground and under water Submerged pipelines,Oil storage tanks,Electric power station
