With a total of 3 patents to his name, Johnson's work has had a lasting impact on the industry.
Latest Patents: One of Johnson's latest patents is for a differentially coated galvanized steel strip. This innovative product is produced by hot dip coating both sides of a steel strip while adjusting the weight of the coating metal on opposite sides. This process results in a light coated side and a heavy coated side. The strip undergoes a precooled treatment to solidify the heavy coated side, followed by a heating and cooling process that transforms the light coated side into an iron-zinc alloy throughout. The heavy coated side retains an outer layer of coating metal, preventing any bleed-through of the iron-zinc alloy to the surface.
