The W40x235 is a wide-flange structural steel beam reference for engineers, detailers, fabricators, and students working with steel framing information. This page presents the source-listed dimensions and section data alongside the applicable AISC reference and a downloadable DWG file.
Use the values below as a reference for identifying the shape and coordinating drawings. Member selection, connection design, stability checks, and other structural decisions require project-specific engineering verification.
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.
Depth : 1008.4 mm
Width : 302.3 mm
Web Thickness : 21.1 mm
Flange Thickness : 40.1 mm
Root Fillet Radius : 30 mm
Sectional Area : 445.81 cm2
Unit Weight : 350 kg/m
How to read the W40x235 reference
The listed depth and width describe the overall envelope of the W shape. Web thickness relates to the central web, while flange thickness describes the horizontal flange material. The root fillet radius identifies the curved transition between the web and flange, which can matter when checking clearances, detailing connections, or modeling the profile in CAD.
Sectional area and unit weight are provided for quantity takeoffs, material comparisons, and reference calculations. They should not be treated as a complete set of design properties. Design work may also require additional section properties, unbraced-length checks, connection requirements, material specifications, and applicable project criteria.
AISC reference and drafting resource
The source identifies AISC 360-16, the 2016 edition of the Specification for Structural Steel Buildings, as the governing reference associated with this entry. AISC requirements cover the design, fabrication, and erection of steel structures in the United States; users should confirm the edition and project requirements that apply to their work.
The downloadable W40x235 DWG can support drawing coordination and preliminary CAD work. Confirm scale, units, layer conventions, and the profile geometry before using the file in a project document. Related resources may include the site’s W-shape references, steel section properties, connection detailing guidance, and CAD/DWG library.
W40x235 frequently asked questions
What type of section is W40x235?
W40x235 is identified on this page as a W beam, also called a wide-flange structural steel shape.
Which standard is referenced for this W shape?
The source references AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings. Always verify the governing requirements for the specific project.
What information is listed for the W40x235?
The reference includes depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These values are intended to identify and describe the listed section.
Is the W40x235 DWG ready for construction use?
The DWG is a drafting resource, not a substitute for design review. Check its geometry, units, scale, and project coordination before incorporating it into construction documents.
Can the listed data alone be used to select the beam?
No. Beam selection depends on loads, spans, support conditions, bracing, material requirements, limit states, connections, and applicable design criteria. A qualified engineer should verify the final selection.
