Source corrosion-resistant coating for solar racking and BOS components in coastal and corrosive environments. Custom coating services on Sunhub.
Coating matched to site corrosion exposure
Coating matched to corrosion exposure
Coastal, agricultural and industrial sites expose steel and aluminum components to corrosion standard galvanization doesn't fully address, and coating options here get specified against the actual site environment.
Applied to the project's actual hardware
Coating runs on the specific brackets, rails and enclosures in a project's bill of materials, not a generic stock finish applied after the fact.
Documented for warranty and durability claims
Coating specification and application data are documented, which matters when a racking manufacturer's structural warranty depends on protective finish being applied correctly.
Longer hardware life, warranty intact
Extend hardware life in harsh environments
Coating gets matched to actual corrosion exposure instead of a one-size finish that underperforms on a coastal or industrial site.
Keep the structural warranty intact
Documented coating application supports a warranty claim instead of creating a gap in it.
FAQs
When does solar racking need coating beyond standard galvanization?
Standard galvanization handles many inland environments, but harsher exposure, coastal salt air, high humidity, industrial or agricultural atmospheres, and aggressive soils, often calls for additional coating to hit the intended service life. Dissimilar-metal contact and specific warranty durability targets can also drive the decision. Matching the coating to the site's actual corrosion exposure, rather than a default finish, is what protects the hardware over decades.
What coating options exist for coastal or high-corrosion sites?
Common approaches for aggressive environments include powder coating over a prepared or pre-galvanized surface, duplex systems that pair hot-dip galvanizing with a coating, and higher-grade material selection where appropriate. The right choice depends on the alloy, the corrosion category of the site, and the warranty being claimed. Specifying the system against the actual exposure, then documenting it, is what stands behind durability claims later.
Does coating affect a racking system's structural warranty?
It can, in both directions. Applying coating improperly or altering hardware outside the manufacturer's guidance can void a structural warranty, while a correctly specified and documented coating often supports the durability claims a warranty depends on. The key is applying the coating to the project's actual hardware in a way that stays within manufacturer requirements and keeping the documentation to prove it.
