ASTM A123 for Structural Steel Products
Any materials rejected by an inspector for any reason except embrittlement may be stripped, regalvanized, and resubmitted for inspection. The ASTM specifications A143/A143M, ASTM A384/A384M, and ASTM A385 provide guidelines for preparing products for hot-dip galvanizing. The requirements listed in ASTM A123/A123M include coating thickness, finish, appearance, and adherence. These are each defined below and discussed in more detail later in this course.
