For all outdoor applications where the Galvanized material is bare and not painted a minimum G:90 (Z275)is recommended, and for additional protection in corrosive or polluted environments, heavier coated products should be considered. For end uses where the product is painted and a smooth finish is desired, Galvanealed material or Satincoat Steel (A40) should be used. Elongation***38,000-50,000 The hot-dip galvanized coating consists of a series of layers of zinc-iron alloy with successively higher zinc contents towards the coating surface. This lack of alloying also means pre-galvanized sheet is less abrasion resistant than steel galvanized using the batch process. However, the coating thickness difference is significant.
