The W40x324 is a wide-flange structural steel shape identified by its W-shape designation. This reference presents the source dimensional data, section area, unit weight, and a downloadable DWG resource for engineering and drafting workflows.
Use the listed properties as a starting point for reviewing member geometry, comparing W-shapes, and coordinating structural drawings. Final member selection, connection design, stability checks, and detailing should be verified by the responsible engineer using the applicable project requirements.

How to read the W40x324 reference
The dimensional entries describe the overall geometry of the section and the thickness of its principal elements. Depth is the overall section height, while width describes the flange projection across the section. Web thickness and flange thickness help identify the proportions of the web and flanges for modeling, detailing, and section comparisons.
The root fillet radius represents the curved transition between the web and flange. This detail matters when checking clearances, preparing connection details, and interpreting profile geometry in CAD or fabrication drawings.
Section area and unit weight
Sectional area is a geometric property used in steel-member calculations and material takeoffs. Unit weight expresses the mass associated with a unit length of the member and can support estimating, handling, shipping, and framing coordination. These values should not be treated as a substitute for a complete structural design check.
Drafting and design workflow
The downloadable DWG can help detailers and engineers begin a CAD representation of the profile. Confirm drawing units, layer conventions, insertion orientation, and project-specific detailing requirements before incorporating the file into contract documents. Related references such as W-shape terminology, steel section properties, and connection detailing can provide useful context when comparing this shape with other structural sections.
W40x324 FAQ
What type of section is W40x324?
W40x324 is a wide-flange structural steel section. The source reference identifies its geometry and basic section data under the W-shape designation.
What does the W designation mean?
The W designation identifies a wide-flange section family. The remaining designation distinguishes the referenced shape within that family.
What is the unit weight used for?
Unit weight supports material estimating, member-weight calculations, transportation planning, and coordination of steel framing. It does not by itself establish allowable strength or design capacity.
Why is the root fillet radius important?
The root fillet affects the actual transition between the web and flanges. It should be considered when developing connection clearances, modeling the profile, or interpreting fabrication details.
Is the DWG file ready for construction documents?
The DWG is a drafting reference. Review its units, geometry, and project standards before using it in construction documentation, and have the final detailing checked through the project’s normal engineering and quality-control process.
