All of the products listed below andseveral other innovative coatings have beenspecifically developed for T&D asset protection inthe form of corrosion protection.
At Induron, we invest ourselves in your success, your satisfaction,and your reputation. It’s why — for example — we won’t specify themost expensive option when a more economical solution will suffice.Its why we’ve been known to recommend customers postponeprojects that we honestly don’t believe need immediate re-coating.
So what can we do to help you succeed? If it takes climbing towersfor a closer inspection, we climb towers. If you need us to dropeverything for an impromptu face-to-face, we’re on our way. If youneed technical support with any coating-related issue, we’ve got theexpertise. Because at Induron, “getting it right” is who we are, notjust what we do.

Non-deteriorated R - 10 to 0.1% rust
Coating almost intact; red rust covers less than 0.1% of all surfaces, Re-evaluate in 6–12 years
Slightly to moderatelydeteriorated R - 2
0.1 to 1% rustCoating somewhat weathered; may show slight staining or blistering;
after stains are wiped off, less than 1% of surface area shows rust, blistering, loose mill scale, or loose paint film.
Re-evaluate in 3–6 years.
Deteriorated R - 3
1 to 10% rustCoating thoroughly weathered, blistered, or stained, up to 10% of
surface area is covered with rust, rust blisters, hard scale or loose paint film, very little pitting visible.
Needs attention in 1–3 years
Severely deteriorated R - 410 to 50% rust. Large portion of surface is covered with rust, pits,
nodules, and non-adherent paint. Pitting is visible. Needs attention within 1 year
Totally deteriorated R - 5 Over 50% rust.
Needs immediate attention
Substation Equipment - Transformer and Regulator Cooling Fins (flo-coat only)

90% of Transmission Towers and Poles willrequire Systems A or B, however somestructures will corrode past the ideal“window of opportunity” and require moresurface preparation, or more primer, orgreater film thickness. Other structures willbe located near corrosive industries, and/orsevere marine exposures; and may require amore chemical resistant coatings system.Always consult with your Induron T&Drepresentative before finalizing your coatingspecification. Use the 2 charts on this pageto determine your environmental exposureranking, as well as your degree ofdeterioration/corrosion.
