Features and Benefits

Long Term Corrosion Protection-Salt Spray to ASTM B117 in excess of 1000 hours, dependant on coating thickness.
Uniform and Controlled Coating Thickness-Local Coating Thickness of 15-80 microns, thicker coatings available.
Wear Resistant-Due to the iron content of the Sherardized layer, it is the hardest of the zinc finishes.
Excellent Adhesion as the coating forms an alloy layer with the substrate.
Cost Efficient-A Long term and Maintenance Free Coating.
Accepts Top Coats Without the Need for Primer or Surface Finishing.

The Standards In Use For Sherardized Coatings

BS EN 13811:2003

Sherardizing - Zinc diffusion coatings on ferrous products.
The European Standard above has the status of a British Standard and is replacing BS4921.

CLASS OF COATING	LOCAL COATING THICKNESS (MINIMUM VALUE)
CLASS 15	15 µm
CLASS 30	30 µm
CLASS 45	45 µm

Sherardize P1000®

Long Term, Uniform and Wear Resistant Corrosion Protection for Use on Steel Components.

PRODUCT DESCRIPTION

A development of the Sherardizing process, providing an alloyed sacrificial zinc layer, followed by the application of an advanced trivalent passivate system to give greatly enhanced corrosion protection.
