ABSTRACT:
The present invention is a method for zinc plating a meter set assembly used in gas delivery applications, wherein a zinc plating is applied to a steel substrate formed in the configuration of a meter bar. Once the zinc plating is applied through electrodeposition, the meter set assembly is then outgassed in an oven as by curing at 425°-475° F. for 20-35 minutes to drive away any gasses that may be trapped within the zinc coating. Following the outgassing process, a polyester powder coating is applied to the external surfaces of the meter bar.
