Intersolar 2025 — Galvanic Corrosion & Bimetallic Coupling: A Hidden Threat to Your Solar Park. Discover how GALVAGRID can protect your assets with SYNERDIS and SANERGRID
Did you know that galvanic corrosion between bolts, fasteners, and hot-dip galvanized structures can silently compromise the durability of your solar installation?
Each site presents its own corrosive challenges, and mounting structures are especially vulnerable at connection points, where dissimilar metals form galvanic couples. These weak spots can accelerate degradation—especially in coastal, industrial, or humid environments.
GALVAGRID® offers a simple, proven solution :
A specially engineered coating, applied directly to your support structures, channels, bolts, and fasteners. It strengthens the protective barrier, neutralises galvanic potential, and significantly extends the life of your infrastructure.
