Keystone Steel & Wire, the manufacturer of the iconic Red Brand fence, operates under dedicated ZIP code 61641 in Peoria County, Illinois. The company traces its origins to 1889, when Peter Sommer invented a machine to weave steel wire into fence, creating a lightweight, weatherproof option for farmers. Originally named Keystone Woven Wire Fence Co. in Tazewell County, the company built its first steel mill near Peoria in 1902 and changed its name to Keystone Steel & Wire in 1907. The famous red-painted wire that gave Red Brand its name began when a clever employee dipped the top wires in red paint.
For over 125 years, Keystone has been a leader in the steel industry. The Peoria facility is one of the largest wire and rod mills in the United States, producing 700,000 tons of steel annually, primarily from recycled scrap metal.

The Smithsonian's National Museum of American History holds archival materials from this company in its Warshaw Collection of Business Americana.
