The W24x131 is a W-shape structural steel beam profile listed with metric dimensions, sectional area, and mass per unit length. Use the reference data below when reviewing drawings, comparing steel shapes, or coordinating structural and fabrication information.
This page is also a useful starting point for related topics such as W-shape terminology, steel section properties, and structural steel detailing. Always verify the applicable project requirements and design assumptions before using section data in an engineered structure.
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.

Width : 327.7 mm
Web Thickness : 15.4 mm
Flange Thickness : 24.4 mm
Root Fillet Radius : 12.7 mm
Sectional Area : 249.03 cm2
Unit Weight : 195.5 kg/m
How to read the W24x131 reference data
The listed depth and width describe the overall profile envelope. Web thickness describes the thickness of the central web, while flange thickness describes the thickness of the projecting top and bottom elements. These dimensions are useful for drawing coordination, connection detailing, clearance checks, and profile identification.
The root fillet is the curved transition between the web and a flange. That transition is important when checking fit-up, detailing nearby components, or interpreting a CAD representation of the section.
Sectional area describes the cross-sectional steel area. The listed unit weight is expressed in kilograms per metre, so it serves as a mass-per-length reference for material takeoffs and coordination. It should not be treated by itself as a measure of design strength or allowable capacity.
Using the AISC and CAD references
The source identifies the AISC Specification for Structural Steel Buildings (AISC 360-16), the 2016 edition, as the governing reference cited on this page. Use the listed local data as the section reference for this entry, and consult the applicable project specification and engineering checks for design decisions.
The linked DWG resource can support drafting and model coordination. A CAD profile should be checked against the authoritative section data before it is used for fabrication, connection detailing, or design documentation. Related internal references may include AISC steel shapes, structural steel connections, section property terminology, and steel detailing practices.
W24x131 FAQ
What type of section is the W24x131?
It is identified in the source as a W beam, commonly described as a wide-flange structural steel shape.
What profile information is provided?
The reference lists the depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight for the profile.
What does the root fillet represent?
The root fillet is the rounded transition where the web meets a flange. It is relevant to accurate profile representation and to detailing work near the web-to-flange junction.
Can the listed unit weight be used as a design capacity?
No. The unit weight is a mass-per-length reference. Structural resistance requires the applicable material, stability, loading, connection, and code checks.
What is the DWG file used for?
The DWG file is intended to support CAD drafting and coordination. Confirm the profile geometry against the page’s authoritative reference data before relying on it for fabrication or engineering documentation.
