Norton Corrosion

What Norton Corrosion does

Norton Corrosion Limited (NCL), founded in 1959 and headquartered in Woodinville, Washington, is a full-service corrosion control engineering firm and manufacturer operating as a division of Tanknology. The company designs, manufactures, and installs cathodic protection (CP) systems that prevent electrochemical corrosion of metallic infrastructure in soil, seawater, and industrial environments using both galvanic and impressed current methods. Its proprietary hardware lines — the Bayanode® probe anodes and Morganode®/Morganode II marine anodes — have been deployed for over 40 years in condenser waterboxes, large diameter piping, storage tanks, and offshore pipe/sheet pile applications.

NCL operates a vertically integrated business spanning engineering and design, in-house USA manufacturing of CP components (anodes, reference electrodes, rectifiers, junction boxes, cable, backfill, test instruments), NACE-certified field installation, inspection, surveying, laboratory analysis, and a proprietary anode rebuilding service. Revenue is generated through a mix of professional services (engineering, inspection, surveying, installation, repair) and hardware sales, priced on a quote-based, project-by-project basis via direct enterprise field sales (phone, email, and project engagements). The company holds general contractor licenses across multiple states plus federal contracting credentials (CAGE Code, NAICS codes, DOT carrier), enabling both commercial and defense work.

The customer base is concentrated in power generation, petrochemical and pipelines, marine/offshore, defense and military (US Navy, Air Force, Army, Coast Guard), civil/municipal water, transportation and aviation (including Boeing), agricultural irrigation, and processing/manufacturing. Notable named customers include Florida Power & Light, Duke Energy, Constellation, NRG, BP, Kinder Morgan, Phillips 66, Black & Veatch, Burns & McDonnell, Kiewit, and King County. NCL frequently serves as a subconsultant to engineering primes and has completed projects across the US plus Mexico, Colombia, and Thailand.
