Standard Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products (ASTM Designation: A 123/A 123M-17)
standard by American Association of State and Highway Transportation Officials, 2019


AASHTO M 111M/M 111-19 covers the requirements for zinc coating (galvanizing) by the hot-dip process on iron and steel products made from rolled, pressed and forged shapes, castings, plates, bars, and strips.

This specification covers both unfabricated products and fabricated products, for example, assembled steel products, structural steel fabrications, large tubes already bent or welded before galvanizing, and wire work fabricated from uncoated steel wire. This specification also covers steel forgings and iron castings incorporated into pieces fabricated before galvanizing or which are too large to be centrifuged (or otherwise handled to remove excess galvanizing bath metal).

This specification does not apply to wire, pipe, tube, or steel sheet which is galvanized on specialized or continuous lines, or to steel less than 0.76 mm [22 gauge (0.0299 in.)] thick.

The galvanizing of hardware items that are to be centrifuged or otherwise handled to remove excess zinc (such as bolts and similar threaded fasteners, castings and rolled, pressed and forged items) shall be in accordance with M 232M/M 232.

Fabricated reinforcing steel bar assemblies are covered by the present specification. The galvanizing of separate reinforcing steel bars shall be in accordance with ASTM A 767/A 767M.
