          Tolerances

          Cold rolled (UC): Tolerances in accordance to EN 10131.

          Hot rolled (UC): Tolerances in accordance to EN 10051.

          Hot-dip galvanized (GI, GA, ZA): Tolerances in accordance to EN 10143.

          Customized dimensional and shape tolerances are available upon request.

          Coatings

          The metal coating options for Docol products include:

          Hot-dip zinc coating (GI) consists almost entirely of zinc (>99%). It is lead free, resulting in a small zinc spangle size. The coating provides good corrosion protection.

          Galvannealed coating (GA) is a zinc-iron alloy coating having an iron content of approximately 10%. Galvannealed is produced by post-heat treatment in continuous hot-dip coating process. Galvannealed provides excellent resistance weldability and corrosion protection of painted products.

          Galfan coating (ZA) is a zinc-aluminium alloy coating having the eutectic composition approximately of 95% Zn and 5% Al. Galfan is produced in continuous hot-dip coating process. Galfan has better anticorrosive and forming properties than conventional hot-dip zinc coating (GI).

          Electrogalvanized coating (EG) is applied continuously by electro deposition. The coating consists of zinc (>99%). Electrogalvanized steel is characterized by its excellent surface quality and uniform coating thickness.

          Grade specific availability of metal coatings for Docol products is given in the Mechanical properties table (Coating).
