Bethanization is a process patented by the Bethlehem Steel Company to protect steel from corrosion by plating it with zinc,[1] a process similar to electrogalvanization. In advertising materials, Bethlehem Steel claimed the process was more effective than hot dip galvanization, the most common means of using zinc to protect steel.[1]

In 1936, Bethlehem Steel spent $30 million (1936 dollars) to build a factory in Johnstown, Pennsylvania capable of creating large amounts of Bethanized wire.[2]
