6、n general, the surface of the electrolytic coated steel is better/smoother than the Hot Dip coated products. Coating weight tolerance ranges closer than those shown in Table V can be obtained by negotiation with specific steel suppliers. Engineering can specify the electrolytic process by adding the
7、 prefix EG to the seven character alpha-numeric code. The two-side galvanized class 60G/60G is the most commonly used class in Navistar design. A.4 PREFERRED SIZES and TOLERANCES FOR COATED SHEETWhenever practical, Engineering should select one of the preferred thickness values for coated sheet stee
8、ls as shown in CEMS A-6, Part I, Tables 11 and 12 (thickness values include both the metal and the coating). Utilization of preferred sizes contributes to reduced inventories and minimized cost. Engineering Design should indicate thickness on drawings by nominal values (not minimum values), and comm
9、ercial gage numbers should no longer be shown. Tolerances for thickness are plus and minus about the nominal value.
