AISI Partners with LineBuilders to Provide Communication System The American Iron and Steel Institute (AISI), Washington, D.C., and LineBuilders Inc., Seattle, Wash., have partnered to provide a new information and communication system for steelmakers and suppliers. The online service is a facility-oriented equipment directory and specification repository. The information system breaks each facility down into equipment components and services, and a communication system allows users to easily send sales-call or bid requests to multiple suppliers and track responses.
