What does ASTM A153 mean?
Emily Wilson What does ASTM A153 mean?
ASTM A153 governs zinc coatings applied by the hot-dip process to hardware products such as castings, fasteners, rolled, pressed, and forged products, and miscellaneous threaded objects that will be centrifuged, spun, or otherwise handled to remove excess zinc.
What is ASTM F2329?
ASTM F2329 covers the requirements for hot-dip zinc coating applied to carbon steel and alloy steel bolts, screws, washers, nuts, and special threaded fasteners applied by the hot-dip coating process. It is intended to be applicable to fasteners that are centrifuged or otherwise handled to remove excess zinc.
How thick is hot-dip galvanized coating?
3-8 mils
Typical galvanized coatings range from 3-8 mils (75-200 mi- crons) thick. When designing and detailing tapped holes, the increased thickness is important.
What is hot-dip galvanized fasteners?
Hot-dip galvanizing, in which steel fasteners are dipped in a hot bath of zinc, is a particularly effective way to form a protective layer of zinc that offers excellent defense against corrosion, including outstanding durability, uniformity of coverage and longevity.

What is ASTM A653?
Definition. A653/A653M – Standard Specification for Steel Sheet, Zinc-Coated (Galvanized) or Zinc-Iron AlloyCoated (Galvannealed) by the Hot-Dip Process. This specification covers steel sheet, zinc-coated (galvanized), or zinc-iron alloy-coated (galvannealed) by the hot-dip process in coils and cut lengths.
What is ASTM A563 Grade A?
ASTM A563 is a standard material specification for carbon and alloy steel nuts general structural and mechanical uses on bolts, studs, and other externally threaded fasteners.
Can galvanized steel be repaired?
When it comes to repairing galvanized steel in the field, there is no limitation to the size that can be repaired. The zinc coating is difficult to damage, and field fabrication that requires removal of the coating should be minimized as much as possible.
What is zinc dust paint?
Zinc painting, commonly referred to by the misnomer “cold galvanizing,” is the application by brush or spray of zinc dust mixed with organic or inorganic binders. Zinc-rich paints contain 65-95% metallic zinc in dry film, with 92-95% being common. The paints can be brushed or sprayed on to the steel.
