ASTM A153 - Zinc Coating (Hot-Dip) on Iron and Steel Hardware . First, there is a difference between ASTM A153 and ASTM A53.Companies that specialize in galvanizing pipes are familiar with the ASTM A153 specification ("Standard ASTM Specifications American Galvanizers AssociationDec 10, 2017 · ASTM A123/A123M. Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products , covers individual steel pieces as well as assemblies of various classes of material. The material categories covered in the specification include structural steel and plate, strips and bars, pipes and tubing, and wires.
A123/A123M 15. 3.2.2 black, adjdenotes the condition of not galvanized or 3.2.9 specimen, nthe surface of an individual test article otherwise coated. For purposes of this specification the word or a portion of a test article, upon which thickness measure-black does not refer to the color or condition of surface, or to ments are to be performed, which is a member of a lot, or a Cable Tray Selection - Material & Finish Standards coating thickness. Cable, trays hot dip galvanized after fabrication, have a minimum thickness of 1.50 ounces per square foot on each side, or a total 3.0 ounces per square foot of steel, according to ASTM A123. The zinc thickness is controlled by the amount of time each part is immersed in the molten zinc bath as well as the speed at which it Galvanizing Structual Steel - AISC HomeWhat 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, galvanize to ASTM A123/123M, Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products; A153/153M,
1Have I referenced all of the pertinent specications that cover hot-dip galvanizing of steel after fabrica-tion? (ASTM A123 or ASTM A153 and ASTM A385) 2 Is it practical to specify steel of certain chemistry in order to better control the coating thickness and ap-Measurement of the Thickness of Hot Dipped Galvanizing Jun 01, 2020 · The thickness of the galvanized coating is influenced by the overall size, shape, and thickness of the piece, and the chemistry of the steel itself. Table 1 of ASTM A123 provides the coating grade number (which is also equivalent to the minimum average thickness of the galvanizing in microns) based on the type of item being galvanized (also called the Material Category).
