Steel reinforcing bar (steel rebar) assemblies are used in building and road/bridge projects where they are embedded in concrete. These products are rolled round deformed bars which are further detailed, cut, bent and/or tied into assemblies to prepare for installation. Additionally, merchant bar quality (MBQ) steel shapes are angles, flats, rounds, channels and others used in a variety of building, industrial and equipment products. For use in the construction market, they are detailed, cut, drilled, bolted, welded and otherwise processed at the fabricator to be prepared for installation. Steel bar produced by Nucor’s bar mill are defined by the following ASTM standards: – ASTM A36/A36M-19 Standard Specification for Carbon Structural Steel – ASTM A529/A529M-19 Standard Specification for High-Strength Carbon-Manganese Steel of Structural Quality [Grades 50, 55] – ASTM A709/A709M-18 Standard Specification for Structural Steel for Bridges [Grades 36, 50] – ASTM A572/A572M-21 Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel [Grades 50, 55] – ASTM A615/A615M-20 Standard Specification for Deformed and Plain Carbon Steel Bars for Concrete Reinforcement [Grades 40, 60, 75, 80, 100] – ASTM A706/A706M-16 Standard Specification for Deformed and Plain Low-Alloy Steel Bars for Concrete Reinforcement [Grades 60, 80]
