2024 is the Institute’s centennial anniversary! One hundred years (1924-2024) of industry impact is no small feat, and we’ve been celebrating throughout the year! In October of 1924, thirty-three owners and executives of twenty-five companies involved in the fabricating and distribution of new billet-steel reinforcing bars gathered at the William Penn Hotel in Pittsburgh, PA, to establish a trade association for their industry. The purpose of the new organization was to promote and actively support the use of steel reinforced concrete in construction, as well as to address immediate challenges faced by the industry. The founding members named their new organization the Concrete Reinforcing Steel Institute (CRSI). Although most attendees were from the industrialized areas in the northern states, CRSI’s aspirations were national from the beginning, as the new association, headquartered in Chicago, IL, was to serve members across the country. CRSI was one of many trade associations that began shaping the U.S. business environment in the first decade after World War I ended. From the perspective of its founding members, CRSI addressed an immediate need at a time when the concrete reinforcing steel industry found itself at a peak of production. In the absence of uniform contracts, reliable credit information and enforcement mechanisms they could rely on, rebar fabricators were regularly chasing customers to get paid for their products. Having their own trade association provided them with the opportunity to bond together as a body to get more legal authority and power to help establish order and discipline and ensure that they got paid. . . . #100thanniversary #100years #centennial #century #rebar #rebarfabrication #rebarfabricators #rebarfabricator

America’s First Reinforced Concrete Bridge is the Alford Lake Bridge, built by Ransome Concrete Company, an innovator in reinforced concrete design, in 1889. It is still in use today in Golden Gate Park, San Francisco, California. Cold twisted bars were used for reinforcement. The bridge survived the 1906 San Francisco earthquake, among others, with no damage and was designated a historic civil engineering landmark by the American Society of Civil Engineers in 1969. . . . #rebar #rebardetailer #steelreinforcement #rebarplacer #concreteconstruction #structuralengineering #rebarsplicing #StructuralEngineer #concretedesign #rebardetailing #StructuralStrength #BuiltToLast #drafting #detailing #concreteindustry #rebarfabrication #rebarfabricator #rebarinstallation #rebarconstruction #rodbuster #ironworker #jobsite #steelRebar
