The W21x68 is a W-beam section listed with dimensional and basic section data for structural steel reference work. This page preserves the authoritative local values and helps readers interpret the terminology used in the listing.
Use the dimensions and properties below when reviewing steel shape references, preparing drawings, or coordinating a model with design and fabrication documentation. The accompanying DWG resource can support drafting workflows, but section selection and structural adequacy 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.

Web Thickness : 10.9 mm
Flange Thickness : 17.4 mm
Root Fillet Radius : 12.8 mm
Sectional Area : 129.03 cm2
Unit Weight : 101.3 kg/m
How to read the W21x68 listing
The W designation identifies the section as a W-beam. The complete designation is the shape identifier used to locate the section in structural steel shape tables and CAD libraries. Keep the designation unchanged when searching schedules, connection details, analysis models, or fabrication documents.
Dimensions and section data
The source listing reports overall depth and width, web and flange thicknesses, and the root fillet radius. These values describe the rolled geometry and are useful for checking clearances, detailing connections, coordinating plates or other members, and reviewing a drawing against the selected shape.
The listed sectional area and unit weight are reference properties of the section. They should not be treated as design strength or allowable capacity. Strength and serviceability checks also depend on the applicable design provisions, material information, loading, restraint, connection behavior, and project conditions.
AISC reference and CAD use
The listing refers to the AISC Specification for Structural Steel Buildings (AISC 360-16), identified in the source as the 2016 edition. Consult the applicable project requirements and current engineering procedures when using this information for design, fabrication, or erection.
For drafting, download the linked DWG and verify units, insertion settings, orientation, and detailing conventions before incorporating it into a production drawing. Related resources on steel connections, steel detailing, and CAD/DWG references can help with document coordination.
Frequently asked questions
What type of section is W21x68?
W21x68 is identified in the source as a W-beam. The W designation is the section-series identifier used in structural steel shape references.
What information is provided for W21x68?
The listing provides depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. It also includes an AISC reference and a DWG download link.
Can the listed sectional area or unit weight determine beam capacity?
No. These are section reference properties, not a complete design check. Capacity depends on the applicable design method, material, loading, support and restraint conditions, member length, and connection details.
How should the W21x68 DWG be used?
Use the DWG as a drafting and coordination aid. Confirm the file’s units, scale, orientation, and project detailing requirements before using it in issued documentation.
