Marcegaglia launched OneZinc, an innovative carbon steel welded tube featuring external electrogalvanized coating. The product emerged from 24 months of research & 17,000 testing hours. OneZinc eliminates traditional post-galvanization processes through streamlined manufacturing using pre-coated coils. The tube offers 6-8 micrometer zinc coating thickness for residential & industrial plumbing applications, particularly press-fitting systems requiring precise dimensional tolerances.
