The W40x264 is a wide-flange structural steel beam designation used to identify a specific W-shape in the AISC reference system. The source data below provides its listed geometric dimensions, sectional area, and unit weight for reference and drafting work.
Use this page alongside related W-shape steel sections, section properties, and structural steel terminology resources when comparing beam sizes or coordinating drawings. The included DWG file can support CAD workflows, while final member selection and design verification remain engineering responsibilities.
W Beam
refer to : AISC 16
the American Institute of Steel Construction (AISC) Specification for Structural Steel Buildings (AISC 360-16), which is the 2016 edition of the AISC Specification for Structural Steel Buildings. It provides guidelines and requirements for the design, fabrication, and erection of steel structures in the United States.

Flange Thickness : 43.9 mm
Root Fillet Radius : 30 mm
Sectional Area : 499.35 cm2
Unit Weight : 392 kg/m
How to read the W40x264 reference
The W designation identifies a wide-flange beam series, while the remainder of the designation distinguishes this section from other shapes. The listed depth and width describe the overall envelope of the section. Web thickness and flange thickness describe the primary plate elements that form the beam profile.
The root fillet radius is the curved transition between the web and flange. This detail is important when checking clearances, connection detailing, coping, or the fit of adjacent components. Dimensions should be coordinated with the authoritative section data before fabrication or detailed connection work.
Sectional area and unit weight
The listed sectional area is a cross-sectional property used in structural calculations and quantity-related workflows. The listed unit weight expresses the mass of the steel per unit length. Keep these properties distinct from resistance values: the dimensions and weight shown here do not by themselves establish a beam’s design capacity.
Reference standard and CAD use
The source refers to the American Institute of Steel Construction Specification for Structural Steel Buildings (AISC 360-16). This reference provides the design, fabrication, and erection framework identified by the source content. For drawing production, download the W40x264 DWG and verify scale, units, layer conventions, and project-specific detailing requirements before using it in a deliverable.
W40x264 frequently asked questions
What type of section is W40x264?
W40x264 is a W-shape, also commonly described as a wide-flange structural steel beam.
What information is listed for W40x264?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These values are provided in the existing technical content above.
Which AISC reference is identified on this page?
The source identifies AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings.
Can the listed dimensions be used to approve a beam for a project?
No. Section dimensions and unit weight are reference data, not a complete design check. Member selection should account for the applicable loads, support conditions, stability, connections, material requirements, and governing project criteria.
Is a CAD file available?
Yes. The existing content includes a download reference for a W40x264 DWG file. Review the file against the project drawing standard before incorporating it into production documents.
