The iron/zinc alloy coating forms a strong bond with automotive phosphates, resulting in an excellent base for finish painting. This coating-phosphate-paint system offers very effective paint adhesion and corrosion resistance.

The higher contact resistance of this coating, combined with the light coating weight, allows more welds before weld tip replacement. The paintability and weldability advantages are maintained under bending and forming operations. GA product has a dull gray color.

Features

We offer a wide range of precisely controlled chemical compositions with low residuals. Various product attributes, additional offerings and capabilities are shown below.

Surface finish

  • Min. spangle and/or extra smooth
    Standard processing includes temper rolling for consistent surface appearance.
  • Temper rolled for fluting sensitive applications
    Available on non-IF steels for a coil-break free surface. Not available for HSLA steels. Not required for IF steel, as coil breaks will not occur.
  • Exposed
    For applications where final surface appearance is important, including for painted applications.

Surface treatments

  • Oil
    Provides temporary corrosion protection and lubrication for forming operations.
  • Chemical treated (galvannealed)
    Provides barrier corrosion protection.
  • Non chemical treat dry
    No product is added after zinc coating.
  • Prelube
    Provides temporary corrosion protection and extra lubrication for forming operations.
  • Phosphate coated
    Reduces friction for forming operations.
  • LustreLok Cr3 compliant chem treated
