Sheraplex

Sheraplex Coating

Sheraplex™ is a two-stage protective system; the zinc sherardise process is followed by a duplex coating, the coating is an organic barrier layer applied by either a dip and spin or spray technique, The layer is subsequently cured at 200ºC resulting in a uniform, complete coverage coating. The polymeric topcoat can be Delta-Seal blue, silver, green or black.

Sheraplex Hex Bolts

The Sheraplex process outperforms HDS Galvanising and Sherardizing due to the additional coating but is more expensive. Sheraplex bolts require undercut nuts because of the depth of deposit and are not suitable for high-grade 10.9 and 12.9 fasteners because of tempering back.
