Uniform: Sherardizing is a proven anti-corrosion Zinc coating which, when correctly specified and applied, gives a resilient and uniform defence against the corrosion of the base metal, making Sherardizing an ideal coating for small components in addition to irregularly shaped and recessed components with close dimensional tolerances.
Sherardizing provides a highly effective long term coating which is competitive on an initial cost basis.
Sherardizing involves no sources of hydrogen and therefore provides a coating method which is free of sources of embrittlement is suitable for use even in high tensile steels.
