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, MBQ 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 rebar and MBQ produced by Nucor’s Seattle mill are defined by the following ASTM standards: – ASTM A36/A36M-14 Standard Specification for Carbon Structural Steel – ASTM A529/A529-14 Standard Specification for High-Strength Carbon-Manganese Steel of Structural Quality [Grades 50, 55] – ASTM A709/A709M-16a Standard Specification for Structural Steel for Bridges [Grades 36, 50] – ASTM A572/A572M-15 Standard Specification for High-Strength Low-Alloy Columbium-Vanadium Structural Steel [Grades 50, 55] – ASTM A615/A615M-16 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] – ASTM F1554-15e1 Standard Specification for Anchor Bolts, Steel, 36, 55, and 105-ksi Yield Strength [Grade 55] – ASTM A588/A588M-15 Standard Specification for High-Strength Low-Alloy Structural Steel, up to 50 ksi [345 MPa] Minimum Yield Point, with Atmospheric Corrosion Resistance [Grade B] – ASTM A29/A29M-15 Standard Specification for General Requirements for Steel Bars, Carbon and Alloy, Hot-Wrought [Grades 1006, 1008, 1010, 1012, 1015, 1018, 1022, 1045, 1527, 4140]
