AT&T Helps O'neal Steel Increase Productivity

Birmingham, Alabama, April 18, 2006

AT&T Inc. (NYSE: T) announced today that it will help O'Neal Steel, the nation's largest family-owned metals service center, implement a networking solution that will support the rollout of advanced applications. Under the $2 million three-year contract, AT&T will upgrade O'Neal's network to an Internet Protocol Virtual Private Network (IP VPN). Since IP is a standardized communications protocol, O'Neal will be able to consolidate multiple legacy networking technologies onto a single, secure, reliable and easily scaled network infrastructure that can carry voice, video and other types of data traffic.

In addition, O'Neal Steel's network will leverage Multiprotocol Label Switching (MPLS), which provides two main benefits. First, O'Neal will be able to seamlessly mesh different types of legacy networking technologies such as ATM and Frame Relay, inherently creating added network redundancy. Second, MPLS will enable the international metals service provider to prioritize network traffic. This guarantees that Voice over IP (VoIP), video and other business-critical applications will have access to the bandwidth they need for high performance. Such prioritization of network traffic has allowed companies like O'Neal to transition to VoIP, to centrally host business applications and to provide crystal-clear videoconferencing among locations around the world.

These AT&T services will expand O'Neal Steel's telecommunications framework and enable growth in capabilities as the company continues to increase its use of virtual and digital technology for managing information systems. The contracted solution will bring services to 33 O'Neal Steel locations nationwide and augment the Managed Internet Services currently provided by AT&T at those locations.

"In a competitive metals market, we need to use technology to keep improving productivity," said Kenny McCrary, technology manager at O'Neal Steel. "AT&T is helping us develop a solid framework for expanding our capabilities and for utilizing the newest applications to perform effectively and efficiently."

About O'Neal Steel
After more than 80 years in business, O'Neal Steel is now the United States' largest family-owned metals service center. That's an important distinction because it means the family who started the company, and has guided its growth, continues to be instrumental in its operation today. In the fourth quarter of 2005, O'Neal further extended its product line with the acquisition of TW Metals, a service center specializing in pipe, tube, bar and rod in stainless, aluminum, alloy and carbon, as well as a variety of high alloys such as nickel and titanium. In early 2006, O'Neal acquired Timberline Steel, expanding O'Neal's full-line capability to service customers in the Rocky Mountain Region. You can learn more about O'Neal Steel at
