            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).

                Docol metal coated products are available with surface quality for unexposed applications.

                In addition to these coating masses, OEM specific coatings and single sided EG coatings are available upon request.

                1) For hot-dipped (GI, ZA, GA) hot rolled (HR) grades, the coating mass tolerance is increased to 30 g/m² by increasing the upper limit.

                Surface Treatments

                Uncoated (UC): available as oiled.

                Hot-dip galvanized (GI, GA, ZA): available as oiled and/or chemically passivated.

                Electrogalvanized (EG): available as oiled and/or chemically passivated or phosphated.

                All surface treatments are in accordance with RoHS directive (2011/65/EU) and do not contain Chromium VI (Cr6+). Surface treatments provide only temporary surface protection during transportation and storage. In order to avoid corrosion damages, care must be taken to keep the products dry during transportation and storage. If they become wet, they must be separated and situated so that they are dried quickly.

                Fabrication and Other Recommendations

                For information concerning fabrication, see SSAB´s brochures on www.ssab.com or consult Tech Support.

                Appropriate health and safety precautions must be taken when bending, welding, cutting, grinding or otherwise working on the products.
