ArmorGalv® is the trade name for a thermal diffusion galvanizing technology developed by the Distek Group in 1993. It is a method of applying a uniform, sacrificial, zinc- iron alloy coating using a metallurgical vapor diffusion process.
ArmorGalv® can be applied on many surface types including powder metal, steel, stainless steel and castings and forgings.
Using a thermal diffusion galvanizing process, multiple layers of zinc‐iron alloy are formed, from a super corrosion resistant gamma layer to a compact delta layer and then the zeta layer.
Think of an onion, with each layer harder and more corrosion-resistant than the previous one.
ArmorGalv® has a range of product applications for use across several industries.
Using the proven thermal diffusion galvanizing process is straightforward.
Pre-treatment is unnecessary provided the products are a bright metal, as shot blasting acts to degrease and remove any contamination or oxidization.
The products are heated in batches together with zinc powder in closed rotating drums. The diffusion process occurs at temperatures between 320ºC and 450ºC, and during the vapour phase the zinc-iron alloy layers form in and on the surface.
Follow-up treatment requires chrome-free passivation and a clear sealer.
Many of our clients have certain requirements for packing. Their finished goods are packaged for shipment either back to their business – or direct to their clients. We work with you to ensure the ideal outcome.

Thermal diffusion galvanizing is backed by a range of application of a range of technical standards.
These standards include:
Zinc alloy thermal diffusion coatings on steel fasteners, hardware, and other products.
International Standard for Thermal Zinc Diffusion coatings on ferrous products. Specification.
Paints and varnishes. Powder organic coatings for galvanized or sherardized steel products for construction purposes.
