Deep Foundations Under Static Axial Compressive Load1 This standard is issued under the fixed designation D 1143/D 1143M; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Able free of charge from the AGA. Drop me an e-mail at [email protected] and we’ll get a copy to you. Q: What is the ASTM Spec for galvanizing for structural steel shapes? A: The ASTM spec that covers structural steel shapes is ASTM A123/123M. After-fabrication, batch hot-dip galvanizers, including those that are members of the AGA. Zinc Coating Thickness Requirements: ASTM A153 vs. F2329 Dimension ASTM A153 ASTM F2329 Avg. Coating Thickness of Specimens Tested Avg. Coating Thickness of Any Individual Specimen Avg. Coating Thickness of Specimens Tested (Production Lot) Avg. Coating Thickness of Specimens Tested (Batch Lot) Avg. Coating Thickness of Any Individual. RELIABILITY - Able to specified to many standard BS EN ISO 1461, ASTM A123/123 M, and AS/NZS 4680 SPEED OF APPLICATION - Can be applied in minutes FASTER CONSTRUCTION - No site surface preparation is necessary LOWEST LIFETIME COST - Competitive initial cost and long life make hot dip galvanizing the most versatile.
This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. 3.2.6 spangle-free, n—the uniform finish produced on hot-dip zinc-coated steel sheet in which the visual spangle pattern. Hot-Dip Galvanizing to ASTM A123 Fact Sheet Hot-dip galvanizing (HDG) is the process of dipping fabricated steel into a kettle or vat containing molten zinc. While the steel is in the kettle, the iron in the steel metallurgically reacts with the molten zinc to form a tightly-bonded alloy coating that provides superior corrosion protection to steel.

About This Item
Full Description
1.1 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.
1.2 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 Specifications A123-78 and A386-78.

1.3 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 22 gage (0.0299 in.) [0.76 mm] thick.
1.4 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 Specification A153/A153M.
1.5 Fabricated reinforcing steel bar assemblies are covered by the present specification. The batch galvanizing of separate reinforcing steel bars shall be in accordance with Specification A767/A767M and the continuous galvanizing of reinforcing bars shall be in accordance with Specification A1094/A1094M.

1.6 This specification is applicable to orders in either inch-pound units (as A123) or SI units (as A123M). Inch-pound units and SI units are not necessarily exact equivalents. Within the text of this specification and where appropriate, SI units are shown in parentheses. 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.
1.7This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
