Hot Dip 101

When designing and fabricating steel for the hot-dip galvanizing process, certain considerations must be taken into account. Communication between the architect/engineer, the fabricator and the galvanizer will ensure everyone is on the same page and has a complete understanding of what will be happening.

By clicking on one the link below, you will be directed to the American Galvanizers Association's website and to specific information that you are seeking. By adopting these practices, in conjunction with the standards in ASTM A 385 for Providing High Quality Zinc Coatings, you will ensure your expectations are met and achieved.

Design Issues
