Product Features
- Compact structure: lower chemical segregation, no gas porosity, no internal shrinkage, and non-metallic inclusions
- Cast in taper pin or bolt connection ensures superior cable connection at the anode head
- High anode utilization of between 60% ~ 70% of the anode weight results in an economic CP solution

What are HCSI Solid Stick Anodes?
HSCI Solid Stick anodes provide a high performing corrosion protection solution.
Our HSCI are manufactured using a metal or “chill” casting method, which guarantees a rapid solidification of the molten metal which results in a superior grain structure to standard sand-cast anodes.
Chill casting also assures a consistent weight and greater density of the anode, there is less flake grain boundaries and low chemical segregation.
HSCI Anodes are extremely strong and tolerate drop impact tests to more than twice the height of sand-cast anodes.
Stick anodes are available with or without a chrome addition. The chrome addition enhances the performance of the anode.
