The W14x120 is a wide-flange structural steel shape listed in the W-shape section of the AISC reference data. This page brings together its reported dimensions, sectional area, unit weight, and a DWG resource for design and drafting reference.
Use the source values below as a dimensional reference, then connect them with related resources on W-shape terminology, steel section properties, and structural steel connection detailing. Shape dimensions alone do not establish member capacity or replace project-specific engineering checks.
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.

Width : 373.4 mm
Web Thickness : 15 mm
Flange Thickness : 23.9 mm
Root Fillet Radius : 15.2 mm
Sectional Area : 227.74 cm2
Unit Weight : 178.8 kg/m
How to read the W14x120 reference
The listed depth and width describe the overall envelope of the section. Web thickness and flange thickness describe the primary plate elements, while the root fillet radius identifies the transition between the web and flange. These features can affect detailing, clearances, connection fit-up, and compatibility with adjoining components.
The reported sectional area is a geometric property of the steel cross-section. The unit weight is useful for estimating material quantities and handling considerations, but it should not be treated as a substitute for structural resistance calculations. Design checks also depend on the applicable material specification, loading, unbraced conditions, connection details, and governing project requirements.
AISC context and drafting use
The source identifies AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings, as the reference context. Consult the governing project documents and the engineer of record when using this shape in design, fabrication, or erection work.
A DWG file is provided for CAD and detailing workflows. Before using imported geometry, confirm drawing units, scale, layer behavior, insertion settings, and the version of the shape data used by the project. Related internal references may include the AISC shape reference, steel beam section properties, CAD block and DWG guidance, and steel connection detailing concepts.
Frequently asked questions
What is the W14x120?
The W14x120 is a W-shape, also called a wide-flange structural steel section, identified in the AISC shape reference data.
What information is provided for this shape?
The source lists overall depth, overall width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These values describe the reported section geometry and mass reference.
Does the W14x120 designation determine its design capacity?
No. A shape designation and dimensional data do not by themselves determine allowable strength, resistance, deflection performance, or connection capacity. Those checks require project-specific engineering information and applicable design requirements.
What is the purpose of the root fillet radius?
The root fillet is the curved transition between the web and flange. Its geometry is relevant when checking clearances, connection details, coping, fit-up, and interfaces with other components.
Can I use the DWG directly for fabrication?
The supplied DWG is a drafting reference. Verify its units, scale, geometry, and project-specific detailing requirements before using it in fabrication or construction documents.
