Why is Sherardizing the superior alternative to Galvanising?

The superior alternative to Galvanising, providing improved long-standing corrosion protection

Superlative Corrosion Resistance due to being the Hardest of all Zinc Finishes
The corrosion rate of zinc tends to increase with time in highly polluted atmospheres, however the nature of Sherardized coatings makes it less prone to this.
Complete Avoidance of Hydrogen Embrittlement
Hydrogen embrittlement can significantly reduce the ductility and load bearing capacity of steel, resulting in unpredictable failure. The Sherardizing process is hydrogen free and completely dry, thereby avoiding any adverse effect due to hydrogen embrittlement. Alternatively, the Galvanising process absorbs hydrogen, meaning hydrogen embrittlement is much more likely to occur.

Eradication of needing re-threading or further fitting operations
Sherardized coating is uniform on all accessible surfaces without any peak build up on corners or on threads. This characteristic is ideal for coating intricate and irregular shapes which may be difficult to achieve with other processes.
Maintains mechanical properties
Sherardizing takes place within a lower temperature range between 330-425°C, allowing parts to be Sherardized which would otherwise lose their mechanical properties in a Galvanising bath.
Cost efficient
The matte grey finish that Sherardizing produces, creates a textured surface which provides an excellent key for subsequent bonding with oils, paints and lacquers, eliminating the need for additional expensive primers. As a result, the application of paint to a Sherardized coating comes at a reduced cost and increased lifespan as oppose to other processes.
