Solar Structure Coatings for India's Mega Solar Parks
Keep module mounting structures standing for the full 25-year PPA.
A solar plant's modules are warranted for decades — but the galvanized module mounting structures under them start corroding the day they are cut, drilled or scratched during installation. At mega parks like Bhadla, Pavagada and the Gujarat and Khavda zones, thousands of tonnes of MMS steel face abrasive dust, extreme UV, temperature swings and, in coastal zones, salt-laden wind.
G-COAT, SK Formulations' cold galvanizing and solar structure coating, is the site-practical answer: a zinc-rich system that restores galvanic protection on damaged HDG surfaces and coats site-fabricated steel without any re-dipping. EPC contractors and O&M teams use it at installation stage to close out punch lists, and during operations to stop rust streaks before they become structural findings.
Cold Galvanizing / Solar Structure Coating Applications in Solar Parks
Real-world uses of G-COAT across Solar Parks industry.
Where MMS corrosion actually starts
Corrosion on solar structures rarely begins on intact galvanized faces — it starts at field cuts, drilled holes, bolt interfaces, transport scratches and welds on site-modified members. Treating exactly these points with cold galvanizing during construction costs a fraction of the remediation bill five years later, which is why developers increasingly write galvanizing repair into their EPC quality checklists.

Frequently Asked Questions — Solar Parks
Is cold galvanizing an accepted repair for damaged hot-dip galvanizing?
Zinc-rich cold galvanizing is the standard site method for repairing HDG damage where re-dipping is impossible — which is every solar site. G-COAT restores sacrificial zinc protection on the treated area; we share the technical data for your quality team's approval.
How is G-COAT applied at a solar site?
By brush or spray onto a cleaned, prepared surface — practical for punch-list teams moving table to table. Application training and coverage guidance are provided so consumption stays predictable across thousands of touch-up points.
Can O&M teams use it on an operating plant?
Yes. Application does not require shutting rows down, only local access and safe isolation where work is near electrical equipment. Many O&M scopes now include annual corrosion-spot treatment using exactly this method.
Do you supply project quantities to remote sites like Bhadla or Khavda?
Yes — project lots dispatch from our Navi Mumbai plant to site stores with lead time agreed against your erection schedule. Phased deliveries can track your commissioning sequence block by block.
