Corey Steel Company products

Cold finished steel bars are an entire family of products that meet the standards in ASTM A108. Corey makes the product using numerous processes to meet the attributes of an engineered bar product and particular needs of our customers. Corey has been manufacturing cold finished steel bars for almost six decades. Beginning with a single drawing line, we now have one of the most modern facilities with coil fed continuous drawing lines capable of drawing bars from just over a quarter inch to 2 inches in diameter. We also operate draw benches that can make round bars up to 4 inches, hexagon bars to 3 inches, and squares to 2 inches in diameter.A cold drawn bar is produced by drawing a hot rolled bar through a die without heating the material, then shearing it to a desired length and straightening it to commercial tolerances.

Ground and polished bars are the ultimate cold finished steel product. Corey can grind bars to exacting diameter tolerances sometimes as precise as .00025 of an inch per side or .0005 of an inch in total. This process can provide an exceptionally smooth bar with as low as a 10 Ra surface finish.

Not all cold finished steel bars need be cold drawn to meet the tolerances required by our customers. In fact, there exist a number of product subsets in the cold finished steel bar family. A cold drawn bar is produced by drawing a hot rolled bar through a die without heating the material, then cutting it to a desired length and straightening it to commercial tolerances. The resulting product meets exacting tolerances for concentricity, diameter, straightness, length, and surface finish. These tolerances vary depending on the size and chemistry of the material ordered. ASTM A108 sets tolerances and guidelines for different sizes and grades of the product.
