Operating from its production site in Grosseto since 1988, Tecnoseal Foundry S.r.l. focuses entirely on the engineering and manufacturing of cathodic protection systems. The company manages the production cycle of sacrificial anodes for hulls, shafts, and rudders, alongside ICCP (Impressed Current Cathodic Protection) systems. This focus on metal science makes them a technical point of reference for those managing corrosion issues in fiberglass and metal boats. Their production philosophy centers on material purity and specific galvanic applications. Beyond standard zinc and aluminum offerings, Tecnoseal developed the proprietary Bi-Tec alloy, which excludes cadmium, addressing modern environmental standards. Their catalog provides specific anode kits for engine brands like Yamaha, Volvo Penta, Suzuki, and Mercruiser, ensuring that compatibility issues are minimized during routine maintenance. For owners of displacement or planing vessels, the ability to select the correct material—zinc for saltwater, aluminum for brackish water, and magnesium for freshwater—is critical. Tecnoseal provides this level of technical detail, supported by an infrastructure that handles everything from basic propeller anodes to electrolytic monitoring systems. Whether you are performing a seasonal refit or installing a long-term protection system, the brand offers the necessary technical specifications for a correct installation. ## Cathodic protection and material science. Tecnoseal differentiates its catalog by addressing the galvanic demands of different water types and vessel systems. Their engineering approach focuses on the efficiency of the sacrificial metal, ensuring the anode corrodes instead of your running gear or through-hull fittings. Proprietary alloys include zinc, magnesium, aluminum, and the cadmium-free Bi-Tec alloy. Engine-specific kits are available for Honda, Suzuki, Tohatsu, Volvo Penta, Yamaha, and Yanmar. Protection components cover shafts, trim tabs, propellers, and complete ICCP systems.
