This International Standard specifies requirements for hot-dip zinc (galvanized) coating on steel reinforcing bars, wire and welded fabric used in the reinforcement of concrete. It specifies three classes, class A, class В and class С coatings, which differ in coating mass (see 6.2.3). This International Standard does not apply to hot-dip zinc-coated reinforcements for prestressing or components of these reinforcements.
