What Galvotec does

Galvotec Alloys, Inc., founded in 1984 and headquartered in McAllen, Texas, is the oldest and largest sacrificial anode foundry in North America, manufacturing aluminum, zinc, and magnesium galvanic anodes used in cathodic protection systems. Its core products — including the proprietary Galvotec-CW-III aluminum alloy anodes, Galvotec-III sacrificial aluminum bracelet anodes for subsea pipelines, Mil-Spec and ASTM-418-95 compliant zinc anodes, and SUPERMAG magnesium soil anodes — serve corrosion protection applications in seawater, brackish water, fresh water, and high-resistivity soil environments. The company also operates an ISO/IEC 17025:2017 accredited laboratory for anode testing and runs Galvotec Corrosion Services, LLC, a Harvey, Louisiana-based subsidiary offering adjacent cathodic protection services.

The business operates as a privately held, B2B industrial specialty manufacturer with direct sales to enterprise customers, primarily oil and gas majors (Shell, BP, Texaco, Exxon, Samsung Heavy Industries, Nord Stream) and the U.S. Navy (USS New Orleans LPD 18). Its management system is ISO 9001:2015 certified by DNV, and products meet Mil-Spec (Mil-A-18001K, Mil-A-24779, Mil-A-21412A) and ASTM alloy specifications, which act as qualification gates for naval and offshore platform procurement. Pricing is quote-based and not publicly disclosed, with revenue mechanics tied to project-based anode supply rather than subscription or recurring software contracts.

End markets span offshore oil and gas platforms, FPSOs, subsea pipelines, marine vessel hulls, naval ships, water heaters, and — more recently — offshore wind turbine foundations and solar panel farm structures. The company has executed marquee projects including the Shell Bonga FPSO (300,000-ton hull, 1,000+ m water depth), Texaco Petronius (world's tallest free-standing structure at 1,754 ft depth), Shell Brutus TLP at 2,985 ft, and Nord Stream pipeline protection. Geographically, Galvotec reports global project completions across the Gulf of Mexico, Nova Scotia, and Nigeria, supporting a direct industrial sales channel with sales offices in Texas and Louisiana rather than third-party distribution.
