Electro-galvanizing (zinc electroplating) is a high-precision metal finishing process that applies a thin, uniform layer of zinc to steel or iron components using an electrolytic bath. Unlike hot-dip galvanizing, electro-galvanizing provides an exceptionally smooth, bright visual finish with precise dimensional control—making it the ideal choice for intricate parts, threaded fasteners, and components requiring post-plating painting or powder coating.
Fortune Seven provides commercial and industrial electro-galvanizing in strict compliance with ASTM B633 and ISO 2081 standards, offering tailored passivate conversions (clear, yellow, or black chromate) to maximize corrosion resistance.
International Standards Compliance : Processed strictly in accordance with ASTM B633 and ISO 2081 specifications for zinc coatings on iron and steel.
Precision & Uniform Thickness : Delivers exact, controllable coating thickness without clogging fine screw threads or altering tight manufacturing tolerances.
Superior Aesthetic Finish : Produces a clean, smooth, silver-like appearance free of surface drips, run-offs, or rough zinc spatter.
Enhanced Corrosion Protection : Paired with specialized chromate conversion coatings (clear, yellow, or olive drab) to prevent white rust and improve paint adhesion.
