        Coatings

        The metal coating options for Docol products include:

        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 GI and GA the closest informative value refers to EN 10346. For EG to EN 10152.

          Surface Treatments

          Uncoated (UC): available as oiled.

          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.
