Transportation and Infrastructure IndustryThe direct effects of corrosion cost U.S. industry and the government $276 billion annually, according to a study commissioned by the U.S. Federal Highway Administration (FHWA)…and that is only the direct cost of corrosion.

Corrosion can never be eliminated completely, only controlled by such processes as hot dip galvanizing, and by utilizing advanced PVC coatings. PVC coated conduit systems are the proven solution to fight corrosion on public and infrastructure structures. It lessens the effects of costly shutdowns for repairs in corrosive environments. Calbond offers a wide range of PVC coated conduit systems and fittings in both galvanized rigid steel and rigid aluminum. All of our products are UL-Listed and NEMA RN-1 compliant with no exceptions.

  • The corrosive environment of the mining industry limits the lifespan of the processing equipment and as a result, decreases production and endangers the lives of employees within the mine
  • Aerobic and anaerobic microorganisms present in mining water also contribute to the extremely corrosive environments. Aerobic species produce sulfuric acid, making the environment very acidic. Anaerobic microorganisms reduce sulfate and sulfides by using available hydrogen and producing hydrogen sulfide (H2S)
  • PVC coating is available on galvanized rigid steel and aluminum conduit
  • UL® Listed and NEMA RN-1 compliant with no exceptions
  • UL6 Listed with both zinc and PVC as primary coatings, providing two layers of corrosion protection
  • UL PVC adhesion performance tested (DYJC E226472), where conduit is sequentially subjected to air oven conditioning exposure test and resistance salt spray (fog) and adhesion test of ANSI/UL6
  • Specially formulated urethane internal coating provides the longest available product lifecycle
  • Proven to provide corrosion protection at a fraction of the cost of stainless steel conduit
  • Broadest product offering for corrosion protected conduit systems
