Sherardised Plating Screws, Fasteners and Fixings

Sherardising, also known as vapour galvanising and dry galvanising, is the process of galvanisation of ferrous metal surfaces.

The process involves heating up the steel parts up in a closed rotating drum that also contains metallic zinc dust, and possibly sand.

Sherardising is a zinc coating which when correctly applied gives a uniform, resilient defence against the corrosion of the base metal, making it an ideal process for a number of fasteners and fixings including washers, bolts, nuts, springs and castings. The process provides long term corrosion protection due to the zinc alloy layer.

The coating contains some iron content, making it the hardest and most wear resistant of zinc finishes. It is able to withstand damage without loss of performance, and can only be removed by chemical or mechanical means.

Sherardised plating is a highly effective, long term coating which is cost effective due to the initial cost, paired with the pricing of lifetime maintenance and post-treatment.
