W33x291 is a W-shape steel beam reference for engineers, detailers, fabricators, and students working with structural steel documentation. This page presents the source dimensions and section data alongside AISC 16 context and a downloadable DWG resource.
Use the dimensional data to coordinate layouts, compare steel shapes, and support preliminary detailing. For design work, section selection, strength checks, stability, connections, and serviceability must be verified using the applicable project requirements and engineering procedures.
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 : 883.9 mm
Width : 403.9 mm
Web Thickness : 24.4 mm
Flange Thickness : 43.9 mm
Root Fillet Radius : 20.1 mm
Sectional Area : 552.26 cm2
Unit Weight : 433.5 kg/m
How to read the W33x291 reference
The listed depth and width describe the overall envelope of the shape. Web thickness identifies the thickness of the central web, while flange thickness describes the flange material. The root fillet radius is the curved transition between the web and flange and can be important when coordinating connections, plates, copes, and detailing clearances.
The page also reports sectional area and unit weight. Sectional area is useful when reviewing the amount of steel in the cross-section, while unit weight supports material takeoffs and fabrication documentation. These values should be read together with the project’s material specification, design assumptions, and fabrication requirements.
AISC 16 and design context
The source identifies AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings. That specification provides a design, fabrication, and erection framework, but a shape designation alone does not establish allowable use or load capacity. Engineers should verify the complete member design, including applicable limit states, bracing conditions, connections, and project-specific requirements.
DWG and detailing workflow
The linked DWG file can support CAD coordination and drafting workflows. Before using downloaded geometry in production drawings, check the file against the authoritative dimensional data on this page and confirm units, layer conventions, insertion orientation, and detailing requirements. Related references on this site may include W-shape dimensions, steel section properties, connection detailing, and structural steel CAD resources.
W33x291 FAQ
What type of steel shape is W33x291?
W33x291 is identified as a W beam, meaning it belongs to the wide-flange family of structural steel shapes.
What standard is referenced for W33x291?
The source references AISC 360-16, also described as the 2016 edition of the AISC Specification for Structural Steel Buildings.
What information is listed for W33x291?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
Can the W33x291 DWG be used directly for fabrication?
The DWG is a drafting resource. Confirm its geometry, units, and project-specific detailing requirements before using it in fabrication or issued construction documents.
Does the W33x291 designation by itself determine design capacity?
No. Capacity depends on the material, unbraced conditions, loading, limit states, connections, and other project-specific design requirements. Engineering verification is required.
