scope:

This standard covers the requirements for hot dip coatings, both galvanized and galvannealed, applied to a sheet steel substrate utilizing a continuous hot dip process. The substrate may be cold or hot rolled sheet steel. Additional requirements or agreements shall be specified by regional GM Automotive Operations business units (e.g., General Motors North America (GMNA), General Motors Europe (GME), General Motors South America (GMSA), Pan Asian Automotive Technical Center (PATAC) and General Motors Korea (GMK). Coated substrates per GMW14400 are not within the scope of this specification.
