The W21x93 is a W-shape, also called a wide-flange beam, listed with dimensional and section data from the referenced AISC shape information. This page brings the profile dimensions, sectional area, unit weight, and CAD resource together for quick engineering reference.
Use the values below when reviewing a steel framing layout, checking a detail, or comparing W-shapes. For broader context, see the site’s guides to W-shape terminology, steel section properties, and AISC shape references.
W Beam

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 W21x93 designation
In U.S. structural steel terminology, the W identifies a wide-flange shape. The designation that follows identifies the nominal shape series and the section’s published weight designation. The designation is a reference label; the authoritative dimensions and properties for this page are the values listed in the source content below.
What the listed properties describe
- Depth and width: overall profile dimensions useful for coordination, clearance checks, and drafting.
- Web thickness: the thickness of the central web portion of the shape.
- Flange thickness: the thickness of the top and bottom flange portions.
- Root fillet radius: the curved transition between the web and flange, which matters when modeling or detailing connections.
- Sectional area and unit weight: reference properties for material takeoff and engineering calculations. They do not, by themselves, establish allowable capacity or suitability for a particular structure.
Using the DWG reference
The downloadable DWG can support drafting and coordination workflows. Before using the profile in fabrication or construction documents, confirm the drawing units, layer conventions, tolerances, and project-specific detailing requirements. Pair this page with the site’s CAD/DWG resource guide and steel connection detailing guidance for practical workflow information.
The numeric listing is the local reference data for this page. Design decisions should also account for the applicable material specification, loading, stability, connections, fabrication requirements, and review by a qualified engineer.
Frequently asked questions
What type of shape is W21x93?
W21x93 is a W-shape, commonly described as a wide-flange structural steel section.
What information is provided for W21x93?
The reference listing provides overall depth and width, web and flange thicknesses, root fillet radius, sectional area, and unit weight, along with an AISC reference and a DWG download.
Is the listed unit weight enough to select the beam?
No. Unit weight is useful for estimating and coordination, but member selection requires engineering checks for loads, span, stability, connections, material, and applicable project requirements.
What is the W21x93 DWG used for?
The DWG is intended as a drafting and coordination resource. Verify its units and project conventions before incorporating it into design or fabrication documentation.
Why should the profile dimensions be checked before detailing?
Web, flange, and fillet geometry can affect clearances, connection detailing, fit-up, and the accuracy of a CAD model. Confirm the published values against the project’s governing reference before final documentation.
