Strapping Buckles Sherardized
As an alternative to sherardising, buckles made of chemically blackened wire are offered in the market. The result is an even smoother surface and thus less grip.
Chemically blackened strapping buckles are often sold as an alternative to sherardising, but this is not comparable.
Sherardising or diffusion galvanising involves applying a layer of zinc powder filled with fine sand.
This not only makes the buckles rust-proof, it also gives them a much higher grip than blackened or galvanised wire.
Veltkamp buckles are sherardised in accordance with the EN ISO 14713 standard.
