The W27x161 is a W-shape steel section reference for engineers, detailers, fabricators, and students working with structural steel documentation. This page presents the section dimensions and properties recorded in the local AISC 16 reference data, along with a CAD download for drafting workflows.
Use the technical values below as a reference for identifying the section. Design, connection detailing, fabrication, and erection decisions require review against the applicable project requirements and engineering calculations.
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 : 16.8 mm
Flange Thickness : 27.4 mm
Root Fillet Radius : 20.1 mm
Sectional Area : 307.1 cm2
Unit Weight : 241.1 kg/m
How to read the W27x161 reference
The section data describes the overall depth and width, web and flange thicknesses, root fillet radius, sectional area, and unit weight. These terms are useful when comparing W-shapes, checking drawing callouts, coordinating steel members, or preparing quantity information.
Dimensions and section properties
- Depth and width: These describe the overall envelope of the section and help confirm that the selected shape matches the space available in a model or detail.
- Web thickness: This identifies the thickness of the central web. It is relevant when reviewing web detailing and connection arrangements.
- Flange thickness: This identifies the thickness of each flange and supports coordination with flange-connected details and fabrication drawings.
- Root fillet radius: This describes the transition between the web and flange. The fillet should be considered when detailing plates, welds, coping, or other components near the rolled profile.
- Sectional area and unit weight: These are reference properties for material takeoff and structural calculations. They should not be treated as a substitute for the project design checks.
AISC reference and CAD workflow
The source identifies this shape with the AISC Specification for Structural Steel Buildings, AISC 360-16. For related research, readers may also compare this entry with the site’s W-shape dimensions, steel section properties, and structural steel terminology references.
The linked DWG file can support drafting and model coordination. Before using it in production documents, verify the drawing unit settings, layer conventions, scale, and the profile data against the governing project reference.
W27x161 FAQ
What type of section is W27x161?
W27x161 is identified in the source as a W beam, also commonly described as a wide-flange structural steel shape.
What information is listed for this section?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
Which design reference is associated with this entry?
The source refers to AISC 16, specifically the AISC Specification for Structural Steel Buildings, AISC 360-16.
Can the DWG file be used directly for fabrication?
The DWG is a drafting reference. Production use should include verification of units, geometry, project standards, and the applicable engineering and fabrication requirements.
Does the listed unit weight replace a project takeoff or design check?
No. It is a reference property from the local section data and should be confirmed against the project documents and calculation workflow.
