Our Galvannealed products are produced to ASTM-A-653 (Commercial Steel-Type B). This product is produced in a similar fashion to Galvanized, except that when the steel coils exit the zinc bath they are guided through a furnace which enables the complete alloying of zinc and iron. The result is a product with a surface that is dull gray in color and has no spangle. It is suitable for painting after proper preparation. The alloyed coating lacks the ductility of a regular galvanized product and therefore, one might encounter powdering when severely formed.

Almost all of our Galvannealed products carries a coating weight designation of A-60. The A indicates an alloy coating and the 60 is for 6/10 of an ounce of zinc per square foot of coating.
