All markings shall remain legible after galvanizing.
For rectangular sections, calculate required area and check with galvanizer for positioning of openings. Specification for Structural Steel.
ASTM-A | Ahmed Negm –
Assemblies of Different Materials or Different Surfaces 5. Link to Active This link will always route to the current Active version of the standard. Types of embrittlement commonly encountered with galvanized steel are related to aging phenomena, cold working, and absorption of hydrogen.
Critical Dimensions members intersect, vent holes are recommended at both sides This specification covers cold-formed welded and seamless carbon steel round, square, rectangular, or special shape structural tubing for welded, riveted, or bolted construction of bridges and buildings, and for general structural purposes.

Finally, the adherence requirement is for the entire coating to have a strong adherence throughout the service life of the galvanized steel. Certain elements found in steels are known to have finish. Originally approved in This specification covers rolled steel structural shapes for use in building framing or bridges, or for general structural purposes.
Your comments a3885 invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. The vent opening shall be a half circle with its threading is desirable in order to avoid overpickling of the diameter at the base plate D, Fig. Scope excess of about 0.
Traditionally however, steel grating has been 4. A requires a continuous, smooth, and uniform finish with no uncoated areas including on the threads or issues that interfere with its intended use.
This specification covers zinc metal made from ore or other material by a process of distillation or by electrolysis in five grades as follows: Last previous edition approved in as A — Finally, there are requirements for passivating the material chromating to prevent reaction between concrete and the zinc coating, and on bend diameters. Marking for Identification This tubing shall be produced in both welded and seamless sizes and must have the chemical requirements of carbon, manganese, phosphorus, sulfur, and copper.
See Specifying Duplex Systems for more information. Ast studies have shown that even in 1. Any combination of these products can be assembled into a single fabrication and then hot-dip galvanized.
Overlapping or Contacting Surfaces or Both 5. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
What are the differences between ASTM A123/A123M and ASTM A385?
Help Center Find new research papers in: Standard 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. This specification covers the requirements for hot-dip zinc coating applied to carbon aztm and alloy steel bolts, screws, washers, nuts, and special threaded fasteners applied by the hot-dip coating process.
A number in w385 indicates the year of last reapproval. Whenever different analyses of steel or different surfaces of steel are united in an assembly the galvanized finish is not generally uniform in appearance.
However, there are a few additional requirements for galvanized rebar. Enter the email address you signed up with and we’ll email you a reset link. Shearing, Cutting and Punching Before Galvanizing 9. Eddy-current-type thickness measurement is a non-destructive test measuring variations in the impedance of an eddy-current inducing coil caused by coating thickness variations. See attached drawings for Re-machining or otherwise reprocessing of function asmt.
