COAT IT AND FORGET IT.
Induron has the solutions for all of your ElectricTransmission and Distribution maintenancecoatings needs. Whether it is recoatingweathered galvanized lattice type towers,previously painted transmission poles, substationstructures, below-grade tower footings, or largetransformers; Induron has the exact right coatingfor the job! 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

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.
