The W40x294 is a wide-flange structural steel section identified in the source data as a W beam. This reference brings together the listed geometric dimensions, sectional area, unit weight, AISC context, and a downloadable DWG resource for drafting workflows.
Use the dimensional information below when reviewing W-shape dimensions or comparing this section with other structural steel shapes. The listed properties are reference data; member selection, strength checks, stability checks, and connection design require an appropriately qualified engineer.
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 : 304.8 mm
Web Thickness : 26.9 mm
Flange Thickness : 49 mm
Root Fillet Radius : 30 mm
Sectional Area : 556.13 cm2
Unit Weight : 436.6 kg/m
How to read the W40x294 reference
The source content identifies the section through its overall depth and width, web thickness, flange thickness, and root fillet radius. Together, these dimensions describe the cross-sectional geometry used when coordinating steel framing, checking clearances, and reviewing fabrication or detailing information.
Sectional area and unit weight
The listed sectional area is a geometric property of the cross-section. The listed unit weight provides a linear material quantity for estimating member mass and coordinating preliminary steel takeoffs. These values should be kept distinct from design resistance, allowable load, or member capacity, which depend on the applicable design checks and project conditions.
AISC reference and design use
The source refers to AISC 360-16, the AISC Specification for Structural Steel Buildings. That reference provides the design, fabrication, and erection framework identified in the original content. A section designation and tabulated geometry alone do not establish whether the member is adequate for a particular beam, column, brace, or connection application.
For practical design education, pair this page with related references on steel section properties, W-shape terminology, steel connections and detailing, and AISC design basics. Review the governing project requirements, material information, load effects, unbraced conditions, connection details, and applicable engineering checks before using the section in a design.
DWG resource
The downloadable DWG associated with this page can support CAD coordination and preliminary detailing. Treat imported geometry as a reference and verify the drawing against the authoritative section data before issuing fabrication or construction documents.
W40x294 FAQ
What is the W40x294?
W40x294 is the designation used for this W beam reference. The page provides its listed cross-sectional dimensions, sectional area, unit weight, AISC reference, and DWG resource.
What information is listed for the W40x294?
The source lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These are reference properties of the section and should not be interpreted as a complete design-capacity table.
Does the W40x294 designation prove that it is suitable for a project?
No. Suitability depends on the member role, loads, supports, stability conditions, material requirements, connections, and governing design checks. A qualified engineer should verify the complete application.
What is the DWG used for?
The DWG can be used as a CAD reference for layout, coordination, and preliminary detailing. Confirm its geometry and project requirements before using it in issued design or fabrication documents.
