Latest Patents

William L. Johnston's latest patent involves a groundbreaking method for manufacturing light-gage composite-coated flat-rolled steel. This innovative product incorporates low-carbon steel, initially received in cold-reduced continuous strip form, which undergoes meticulous preparation for plating. A corrosion-prevention plating is applied, followed by a selected polymeric coating with lubricant as the final surface treatment. The resulting composite-coated steel substrate is then cold-rolled to decrease its gage. Importantly, the selection of cold rolling steps, alongside the option for stress-relief type of heat treatment before and/or after cold-rolling, allows for the precise tin mill manufacture of composite-coated steel in various weights per unit area, typically ranging from about 35 to about 100 lb/bb.
