|This specification 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).
Note 1—This specification covers those products
previously addressed in M 111-80, ASTM A 123-78, and ASTM A
This specification does not apply to wire, pipe, tube, or steel
sheet that 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.
This specification is applicable to orders in either SI units
(as M 111M) or inch-pound units (as M 111). SI units and inch-pound
units are not necessarily exact equivalents. Within the text of
this specification and where appropriate, inch-pound units are
shown in brackets. Each system shall be used independently of the
other without combining values in any way. In the case of orders in
SI units, all testing and inspection shall be done using the metric
equivalent of the test or inspection method as appropriate. In the
case of orders in SI units, such shall be stated to the galvanizer
when the order is placed.
