MANUFACTURING EXCELLENCE AT SCALE
ABB produces more than 1,560 miles of Ocal conduit annually at the Jonesboro, Arkansas facility—enough to stretch from New York to Denver. This ensures consistent quality and reliable availability worldwide.
The Jonesboro facility combines advanced manufacturing processes with rigorous quality control to deliver corrosion-resistant conduit systems that meet demanding industrial, commercial, and infrastructure requirements. As part of ABB's Installation Products division, this high-volume production capability serves projects of any size across the world.
Every foot of Ocal conduit undergoes strict quality testing to ensure the signature double-layer protection—40-mil PVC coating over 2-mil urethane bonding layer—meets exacting standards. This manufacturing scale allows ABB to serve projects ranging from single-facility installations to multi-site industrial complexes, with the flexibility to accommodate custom color requirements and specialized configurations. The facility's capacity ensures contractors and specifiers can rely on consistent product availability and performance, whether specifying for a single building or coordinating multiple locations across continents.
PROVEN PERFORMANCE IN THE TOUGHEST ENVIRONMENTS
Ocal conduit systems excel in environments where standard rigid conduit fails prematurely. Food processing facilities with frequent washdowns, wastewater treatment plants with corrosive atmospheres, coastal installations exposed to salt spray, and chemical plants with aggressive vapors all benefit from Ocal's double-layer protection. The hot-dip galvanized steel core provides structural strength while the PVC coating shields against corrosion.
The 40-mil PVC exterior coating resists acids, alkalis, and salt spray that would quickly degrade standard conduit. The 2-mil urethane bonding layer ensures the PVC coating remains permanently bonded to the galvanized core, preventing moisture infiltration at the critical interface. This double protection extends system life by decades compared to painted or standard galvanized conduit. Ocal's smooth exterior simplifies cleaning in sanitary environments, while the standard threading and fittings ensure compatibility with existing installation practices. From pulp and paper mills to petrochemical facilities, Ocal delivers reliable protection where corrosion is the primary concern.
CUSTOM COLORS FOR EVERY PROJECT REQUIREMENT
Ocal offers a unique capability in the rigid conduit market: custom color options. Beyond standard gray, Ocal conduit can be manufactured in virtually any color to match architectural specifications, facility color-coding systems, or aesthetic requirements. This flexibility makes Ocal ideal for exposed installations where appearance matters as much as performance.
Custom colors serve practical purposes beyond aesthetics. Facilities use color-coding to identify different systems—power distribution, control circuits, emergency systems, or process piping coordination. Food processing plants, pharmaceutical facilities, and clean rooms benefit from colors that integrate with strict facility protocols. Architects specify custom colors for exposed conduit in retail, hospitality, and institutional buildings where electrical infrastructure becomes part of the design. Ocal's custom color capability eliminates the need for field painting while maintaining full corrosion protection.

FREQUENTLY ASKED QUESTIONS
Ocal features double corrosion protection: a 40-mil PVC exterior coating over a 2-mil urethane bonding layer on hot-dip galvanized steel. This combination provides superior resistance to acids, alkalis, and salt spray compared to standard painted or galvanized conduit, extending system life by decades in harsh environments.
Ocal serves food processing facilities, wastewater treatment plants, coastal installations, chemical plants, pharmaceutical facilities, pulp and paper mills, and petrochemical facilities. Any environment with corrosive atmospheres, frequent washdowns, salt spray exposure, or aggressive vapors benefits from Ocal's superior protection.
Yes. Beyond standard gray, Ocal can be manufactured in virtually any color to match architectural specifications, facility color-coding systems, or aesthetic requirements. This eliminates the need for field painting while maintaining full corrosion protection, making it ideal for exposed installations where appearance matters.
Ocal conduit is available in standard trade sizes from 1/2" through 6" diameter. The complete system includes matching fittings, couplings, and accessories for all sizes, ensuring seamless integration and consistent corrosion protection throughout the installation.
Yes. Ocal PVC-coated rigid conduit meets UL 6 and CSA C22.2 standards for rigid metal conduit. The PVC coating provides additional corrosion protection without compromising the structural integrity or electrical performance required by these standards.
