Webinar Overview:

Stainless steel–long used for bridge expansion joints, concrete reinforcement, and other less visible components–is becoming recognized as a practical choice for bridge structural sections. This webinar will highlight the iconic San Diego Harbor Drive pedestrian bridge project, which uses 2205 duplex stainless steel from Outokumpu as a primary structural component. Outokumpu, a leading producer of stainless steel, presents a panel of experts in the area of bridge design and/or material selection. The webinar will feature individuals who helped to make the San Diego pedestrian bridge a reality including representatives from the materials selection team (TMR Stainless), lead design engineering firm (T.Y. Lin International), and fabricator (AMECO USA). The webinar will also discuss the rapidly expanding role of stainless rebar in extending the life of bridge projects with coastal or deicing salt exposure.
