Appearance American Galvanizers AssociationThe appearance of the hot-dip galvanized coating can vary from piece to piece, and even section to section of the same piece. Many specifiers think newly hot-dip galvanized parts will have a spangle; similar to continuous sheet galvanized steel products.However, batch or after-fabrication hot-dip galvanized steel immediately after galvanizing can take on a number of appearances including HDG Coating Specifications American Galvanizers Association

acceptable according to the specification. Natural Weathering Although hot-dip galvanized (HDG) steel is specified for corrosion protection, di"erences in appearances can be frustrating. 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. British Galvanizing Standard - Galvanizers AssociationThe basic specification for hot dip galvanized coatings on iron and steel articles is defined by a single standard, EN ISO 1461 Hot dip galvanized coatings on iron and steel articles specifications and test methods. However, there are some exceptions to this standard (see thicker coatings below).

Preparing HDG Surfaces for Paint or Powder Coatings. The ASTM specifications D6386 and D7803 which cover preparing the hot-dip galvanized surface for paint and powder coating, respectively,also reference SSPC surface preparation standards. Here is a list and brief summary of the surface preparation standards used in the hot-dip galvanizing industry. Hot Dip Galvanizing SpecificationAn American Galvanizers Association trained Master Galvanizer shall be present when the processes described below are undertaken 1. Pickling shall take place in a solution of 8% to 14% sulfuric acid at a temperature of 140º to 150º Fahrenheit. Calibrated timing devices shall monitor the pickling process. 2. Only the dry kettle galvanizing process shall be used.

An American Galvanizers Association trained Master Galvanizer shall be HDG Coating Specifications American Galvanizers Association Hot Dip Galvanizing Standards - Galvanizers Association The key difference for this Standard from all the other galvanizing Standards is that the article to be hot dip galvanized is usually fabricated into a finished product prior to galvanizing, meaning the article will be ready to use once it leaves the galvanizing factory and all

How is the quality of a galvanized coating determined?How is the quality of a galvanized coating determined?The time to first maintenance for galvanizing is directly proportional to the zinc coating thickness. Therefore, the coating thickness is the most important component in determining a galvanized coating's quality. However, the coating thickness is only one inspection criteria.Inspection of HDG American Galvanizers Association INSPECTION - American Galvanizers Association - Free HDG Coating Specifications American Galvanizers Association

In all cases, the inspection ofhot-dip galvanized steel is conducted at the galvanizing plantprior to shipment of the product.The requirements for hot-dip galvanized coatings are found in three ASTM specifications; A123/A123M Specification for Zinc (Hot-Dip Galvanized) Coatings on Iron and Steel Products A153/A153M Specification for Zinc Coating (Hot-Dip) on Iron and Hardware A767/A767M Specification

Improving the appearance of hot-dip galvanized steel HDG Coating Specifications American Galvanizers Association

Design and specification. The initial appearance of HDG steel is difficult to predict and control for various reas, including design, specification, steel chemical composition, stress induced during steel processing, and cooling rates after galvanizing (Read the American Galvanizers Associations (AGAs) Publication on Hot-dip Galvanized Coating Appearance (2016)). Inspection of HDG American Galvanizers AssociationThe 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.
