Werner Co. was founded in 1922 by Richard D. Werner as "R. D. Werner Co., Inc.," a small business, selling materials for floors, carpets, and walls. The company quickly began to specialize in metal moldings, including a patented brand of metal kitchen trim called ChromtrimTM. R. D. Werner Co., Inc. became a leader in plastics extrusion during the World War II restrictions on civilian metal usage. After the war, Werner started working with aluminum and developed the various types of aluminum ladders for which it is best known. Werner began production of fiberglass ladders in 1963 and in 1981 developed the Glas*Mark® process to personalize fiberglass ladder rails with embedded customer graphics. In 1997, the company restructured, and sold a majority holding to the international investment group Investcorp S.A..
