ASTM Standards

The three governing ASTM specifications for hot-dip galvanizing are:

·        ASTM A123/A123M: Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products

o   Single pieces of steel or fabrications with different types of steel products


·        ASTM A153/A153M: Standard Specification for Zinc Coating (Hot-Dip) on Iron and Hardware

o   Fasteners and small products that are centrifuged after galvanizing to remove excess zinc


·        ASTM A767/A767M: Standard Specification for Zinc-Coated (Galvanized) Steel Bars for Concrete Reinforcement

o   Reinforcing steel or rebar


Previous:Other Galvanizing Standards There are also a few international governing standard to be aware of:
Next:Galvanizing Standards There are certain specifications that have been developed for hot-dip galvanizing in order to produce a high-quality coating. There are three main standards that govern the hot-dip galvanized steel, and a handful of supporting specifications that design engineers and fabricators should become familiar with to promote a high-quality coating and ensure their steel design is suitable for hot-dip galvanizing.
