4.1 The purpose of these color codes is to allow for quick identification of ingot bundles or jumbo ingots of alloys used for hot-dip galvanizing. Other than jumbo ingots, this standard is not intended to imply that each ingot will be color-coded but only that each ingot bundle be color coded.
4.2 Each ingot bundle or jumbo ingot shall be identified with the appropriate color code listed in Table 1.

A UNS assignations were established in accordance with Practice E527. The last digit of a UNS number differentiates between alloys of similar composition.B The North American system is designed to be a simplified version of the International system by eliminating the leading yellow stripe.C Color codes taken from European Standard EN 1179.D GALFAN is a registered trademark of the GALFAN Information Center, Inc.E GALVALUME is a registered trademark of BIEC International Inc., USA.
4.3 The color will be applied as a stripe, or stripes, on two adjacent sides of the ingot bundle or jumbo ingot. The color stripes will be applied to include the ingot bundle foot.
4.4 When using multiple stripes, the colored stripes will be applied from left to right as indicated in Table 1.
4.5 In the absence of a written agreement to the contrary between the supplier and end user, the North American color code will be the standard for all North American transactions; for all other transactions the International Color Code will be used.
