About
Structural Steel W8x31 Beam is a wide-flange steel beam with an 8-inch nominal depth and 31 pounds per linear foot weight. Manufactured through hot-rolling processes at steel mills, these beams are produced from carbon steel billets heated to high temperatures and shaped through precision rolling mills. The W8x31 designation indicates specific dimensional properties: 8.00-inch depth, 8.00-inch flange width, and standardized web thickness. Primary applications include residential and light commercial construction for floor joists, roof beams, and structural framing systems. Key properties include high strength-to-weight ratio, predictable load-bearing capacity, and compatibility with standard connection hardware. The beam meets ASTM A992 specifications for structural steel, offering yield strength of 50 ksi minimum. Makers and contractors purchase W8x31 beams for their versatility in mid-span applications, cost-effectiveness compared to larger sections, and availability from most steel suppliers. Standard lengths range from 20 to 60 feet, with custom cutting services widely available.
