The W12x58 wide flange beam is classified under the AISC 360-16 Specification for Structural Steel Buildings (2016 edition), which provides essential guidelines for the design, fabrication, and erection of steel structures across the United States. This section has a depth of 309.9 mm and a flange width of 254 mm, making it suitable for medium-scale structural framing. Its web thickness of 9.1 mm and flange thickness of 16.3 mm deliver strong load-carrying capability, while the root fillet radius of 15.2 mm improves durability by reducing stress concentration. With a sectional area of 109.68 cm² and a unit weight of 86.1 kg/m, the W12x58 is widely applied in building frames, bridges, and industrial projects where AISC-compliant steel beams are required. Engineers value this shape for its balance of weight and strength in structural design.
