Hollymetal® Action Fasteners Hollymetal® is an alloy consisting of zinc and tin, the alloy of these two metals provides superior corrosion resistance. this unique coating was design by Mechanical Plating in 1982 and approved by BHP as the preferred coating for all severe corrosion sites. Hollymetal® coatings at 45 microns meets the stringent requirements of corrosion resistance, complies and exceeds the 'Standard' AS 3566 for Class 4. Hollymetal® is the coating used on Action Fasteners fasteners, mechanically galvanised under strict in-house facilities here in Australia. The process Mechanical Plating is a process that requires no heat or electrolysis and does not induce hydrogen embrittlement and is suitable for high tensile components |
