A thermal zinc diffusion coating is now offered by SPIROL International Corporation as a standard finish option for their engineered fasteners. The uniform deposition ArmorGalv^® coating provides 1,000+ hours of corrosion resistance without risk of hydrogen embrittlement.

The company is initially rolling out ArmorGalv^® for their roll-formed tubular product lines that include dowel bushings, spring dowels, spacers and compression limiters. The coating will be offered for their other product lines over the course of the next year.

SPIROL offers an array of protective coatings for their product lines to suit various application requirements, and has recently invested in the technology to bring ArmorGalv^® to the market as an in-house process. ArmorGalv^® represents a high-quality, cost-effective method for maximizing corrosion protection, but is also recognized by the U.S. Environmental Protection Agency as approaching zero emissions and has received recognition and awards for its contribution to pollution prevention.
