Exhibit 99.1 Dietrich Metal Framing Announces UltraSTEEL(TM) Framing; Worthington Industries Company Launches Innovative Technology COLUMBUS, Ohio--(BUSINESS WIRE)--Sept. 22, 2005--Dietrich Metal Framing, a Worthington Industries company (NYSE:WOR), today announced that it is introducing to the North American market, Dietrich UltraSTEEL(TM) metal framing products using patented technology of Hadley Industries PLC. A licensing agreement grants Dietrich Metal Framing the exclusive rights to manufacture and sell metal framing using the UltraSTEEL(TM) technology in North America. "We believe this to be one of the most innovative technology offerings in the metal framing industry," said Ed Ponko, President of Dietrich Metal Framing. "Dietrich UltraSTEEL(TM) Framing provides benefits throughout the construction chain." "Hadley Industries is extremely excited to be working with Dietrich Metal Framing," stated Phillip Hadley, Managing Director. "Combining the talents of Hadley's technical staff with Dietrich's technical and marketing abilities should make UltraSTEEL(TM) the most successful metal framing product in North America." UltraSTEEL(TM) is an internationally patented method of altering the characteristics of the base strip steel providing higher strength material. Additional benefits include superior fire performance and enhanced acoustical performance. All of these benefits have been verified by independent sources and the product has received certification by Underwriters Laboratories. In focus groups, building owners and architects were impressed with the significant acoustical and fire benefits of UltraSTEEL(TM). Contractors readily recognized that the product would improve the speed and quality of the building process by allowing for faster and better fastening of both the framing products and wallboard. Dietrich UltraSTEEL(TM) framing products are already available in Florida and will systematically be rolled out across North America as other Dietrich manufacturing facilities convert to the UltraSTEEL(TM) process. Worthington Industries is a leading diversified metal processing company with annual sales of approximately $3 billion. The Columbus, Ohio, based company is North America's premier value-added steel processor and a leader in manufactured metal products such as metal framing, metal ceiling grid systems, pressure cylinders, automotive past model service stampings and laser welded blanks.

Headquartered in Smethwick, West Midlands, England, Hadley Industries is one of Europe's leading manufacturers of cold-rolled sections and allied products. The integration of advanced research and development with an in-house tool manufacturer and the construction of its own rolling machines has earned the Hadley Group its reputation as a major force in cold-roll formed technology.
