The W40x392 is a W beam listed with dimensional, sectional-area, and unit-weight data for structural steel reference work. Use this page to review the section geometry before coordinating design calculations, detailing, fabrication, or CAD documentation.
The source information identifies the AISC 360-16 reference and includes a downloadable DWG file. Compare this entry with related W-shape dimensions and section-property references when evaluating alternative steel sections.
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.

How to read the W40x392 reference
The listed depth and width describe the overall envelope of the section. Web thickness and flange thickness describe the primary plate elements, while the root fillet radius identifies the transition between the web and flange. These dimensions are useful for checking clearances, connection layouts, detailing interfaces, and modeling assumptions.
Sectional area represents the cross-sectional steel area used in section-property and material-quantity workflows. Unit weight expresses the section’s mass per unit length and can support estimating, shipping, handling, and preliminary material takeoff tasks. Confirm project-specific assumptions before using any listed property in a design or fabrication decision.
Design and detailing context
The AISC reference noted in the source identifies the specification framework associated with this entry. A shape listing is a reference aid, not a complete member design: final checks may also involve loading, stability, connections, limit states, material requirements, fabrication conditions, and applicable project criteria.
For drafting workflows, the downloadable DWG can help establish the section profile in CAD. Review the drawing against the authoritative local dimensions before using it in connection details, shop drawings, or fabrication documentation. Related resources on steel connections, W-shape terminology, and structural steel detailing can provide useful supporting context.
W40x392 FAQ
What type of section is W40x392?
W40x392 is identified in the source as a W beam. The page provides its principal dimensions, sectional area, unit weight, and root fillet information.
What does the AISC 360-16 reference indicate?
It identifies the AISC specification reference associated with the listing. The source describes that specification as covering the design, fabrication, and erection of steel structures in the United States.
What is the DWG download used for?
The DWG provides a CAD drawing resource for representing the W40x392 profile in drafting and coordination workflows. Verify the drawing against the source dimensions before issuing design or fabrication documents.
Can the listed data be used for final member design?
The listing is useful for section identification and reference, but it is not a substitute for a complete engineering design check. A qualified engineer should verify the applicable loads, stability conditions, connections, materials, and project requirements.
