Client : Adani Power
Life Extension of Existing Galvanized Power Distribution Towers
Project : Corrosion protection and life extension of existing galvanized power distribution towers
Background : Adani Power’s galvanized towers faced corrosion and surface degradation over time, risking structural integrity. Conventional re-galvanizing was not feasible due to high downtime and operational disruption. Greenovoc’s on-site galvanizing protection coating provided a cost-effective solution to extend tower life, maintain appearance, and minimize disruption.
Challenges Faced :
Structures were already erected and in service
Conventional re-galvanizing required dismantling and transport
High downtime and operational disruption
Need to maintain galvanized appearance while improving protection
Existing Condition :
| Condition | Description |
|---|---|
| Exposure | Galvanized steel structures exposed to environment |
| Corrosion | Visible corrosion and degradation over time |
| Replacement Feasibility | Replacement or dismantling not feasible |
