The forerunner of ArmorGalvĀ® is called Sherardizing, Invented by British metallurgist Sherard Cowper-Coles in 1901. Due to lengthy process times and difficulties controlling thickness, Sherardizing operations were greatly diminished by the 1950’s.

In the 1990’s Distek metallurgists discovered and patented modifications to the zinc powder formula and process controls to reduce time and improve consistency. Distek continues to innovate with new formulations and process improvements today.

There are over 20 Distek Licensees worldwide. Agritek was the first licensee in North America, and has been providing the process for more than 12 years.
