It is important to remember the causes of these di"erences are outside the galvanizers control and do not a"ect the corrosion resistance of the coating.

Contact us on +44 (0) 121 355 8838 if you need any assistance on design, specification or advice on performance. Galvanizing standards - Galvanizers AssociationHot dip galvanizing is a relatively simple process to specify and is covered by a single standard EN ISO 1461. Galvanizers Association can provide detailed advice on compiling your specifications, as well as reviewing design details to maximise the benefits of galvanizing your steel.
6 American Galvanizers Association galvanizing process The galvanizing process consists of three basic steps:surface preparation, galvanizing, and inspection (Figure 3.) surface preparation Surface preparation is the most important step in the application of any coating. In most instances where a coating fails before the end of its expected Inspection - Galvanizers Association of Australia
- IntroductionInspection of Work Before Dispatch to The GalvanizerAppearanceCoating Thickness TestingThe key aspects to inspection of galvanized steel are to check the fabrication of the component prior to galvanizing and then, after galvanizing, to visually inspect the product for defects and measure the coating thickness. Visual inspection is the simplest and most important means of assessing the quality of galvanized coatings. A useful characteristic of the galvanizing process is that if the coating is continuous and has a satisfactory appearance it will be sound and adherent, with a zinc coating Alana Fossa (Hochstein) - Senior Corrosion Engineer Alana Fossa is the Sr. Corrosion Engineer for the American Galvanizers Association (AGA) and the Vice Chairman of the ASTM Subcommittee A05.13 that authors and edits specifications on hot-dip

Hot-dip galvanizing is one of the most economical, maintenance-free corrosion protection systems available. Like any other manufacturing process, hot-dip galvanizing requires conformance with established specifications and is inspected to ensure compliance with such specifications. When specifying galvanized steel in North America, you should be familiar with a number of ASTM specifications, including three main standards and several supporting specifications. Standard Specification for Hot Dip GalvanizingThe galvanized coating shall be continuous, adherent, as smooth and evenly distributed as possible, and free from any defect that is detrimental to the stated end use of the coated article. On silicon killed steels, the coating may be dull grey, which is acceptable provided the coating is sound and continuous.
Dec 10, 2017 · The requirements for hot-dip galvanized coatings are found in three ASTM specifications A123, A153, and A767. Differences in appearance, as well as surface imperfections, can occur, however, in most instances, this is not cause for rejection of the material and does not affect the long-term protection.
