Typical Application

Pure zinc coating (Z) is one of the most commonly used coating types in manufacturing and construction. It is suitable for a range of applications where steel requires a coating that sacrifices protection to prolong the life of the article or structure. Typical applications include:

  • Building and construction components, such as steel structures (purlins and girders);

  • Steel frame decoration;

  • Painted rainwater fittings;

  • Auto parts and body panels;

  • pipes and profiles;

  • engineering components;

  • Household appliances (washing machine frames and panels, cooker plates, dryers, speaker stands, etc.);

  • Industrial products (oil pumps, oil tanks, heat exchangers, fan housings, trapezoidal profiles, cable tray systems);

  • Electronics and agricultural machinery components.
