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.
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).
