The W21x111 wide flange beam is a structural steel section listed in the AISC 360-16 Specification for Structural Steel Buildings (2016 edition). It is widely used in structural applications such as commercial buildings, bridges, and industrial frameworks where a lighter beam is preferred without compromising strength. As one of the lighter members of the W21 series, the W21x111 provides efficient load capacity while reducing dead load and material costs, making it a practical option for economical designs. Engineers, architects, and fabricators rely on accurate sectional data for safe design, precision in fabrication, and effective erection. The table below outlines the key specifications of the W21x111 beam, including depth, width, web and flange thickness, sectional area, and unit weight.
