As a member of the American Galvanizer's Association, Frontier Hot Dip Galvanizing Inc. adheres to all standards, specifications and best practices laid out by the ASTM for our galvanizing service. These specifications govern the coating thickness, adherence and finish for hot-dipped galvanized steel and iron, varying in size and shape.
The hot-dip process requirements for ASTM A123/A123M are based on coating thickness, finish, appearance and adherence for iron and steel products. These products are made from rolled, pressed or forged shapes such as castings, plates, bars or strips.The finish needs to be smooth and uniform with minimum coating to avoid issues that would interfere with the intended use of the fabrication.
This specification lays out the requirements for zinc coating by the hot dipping process on steel and iron products both fabricated and un-fabricated. This applies to steel forgings and iron castings that are galvanized in batches or separately including large hollow sections that are bent or welded before galvanizing as well as wire work that has been fabricated from un-coated steel wire.
This specification applies to steel forgings and iron castings that are too large to be centrifuged to removed excess galvanizing bath metal. This excludes wire, pipe, tub or steel sheet that needs to be galvanized in continuous or specialized lines.
