The W40x392 wide flange beam is a structural steel section defined in the AISC 360-16 Specification for Structural Steel Buildings (2016 edition). Designed for strength and stability, this beam is commonly applied in bridges, tall buildings, and industrial structures where high load-bearing capacity is required. Its wide flange design provides excellent efficiency in distributing structural loads while maintaining durability in construction frameworks. Engineers, architects, and fabricators use these specifications for accurate design, fabrication, and erection of steel structures. The table below summarizes the key properties of the W40x392, including depth, width, flange and web thickness, sectional area, and unit weight.
