Galvanizing Specifications
Hot-dip galvanizing is done in accordance with long established ASTM specifications. There are three main specifications (ASTM A123, A153, and A767) governing the coating thickness, adherence, and finish for hot-dip galvanized steel and a handful of supporting specifications referenced in these specifications cover design practices, repair and touch-up, and painting/powder coating over galvanizing.
Specifying hot-dip galvanizing is simply done by using ASTM specifications developed to produce high-quality galvanized coatings. The main specifications that pertain to hot-dip galvanizing are:
ASTM A123 – general iron and steel products
ASTM A153 – small parts
ASTM A767 – reinforcing steel (rebar)
