The W14x159 is a wide-flange structural steel shape listed in the AISC 16 reference. This page presents its reported dimensions, cross-sectional area, unit weight, and CAD resource in one location for engineers, detailers, fabricators, and students.
Use the existing reference data as the starting point for checking geometry, comparing W-shapes, preparing drawings, and coordinating steel details. Design decisions must be verified against the applicable project requirements and by a qualified engineer.
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.

How to read the W14x159 reference
The W designation identifies a wide-flange, or wide, structural steel shape. The listed depth and width describe the overall envelope of the section, while web thickness and flange thickness describe the principal plate elements that form the cross-section.
The root fillet radius identifies the curved transition between the web and flange. This detail matters when interpreting connection clearances, detailing adjacent components, and comparing the nominal shape with a CAD representation.
Section data and weight
Sectional area describes the amount of steel in the cross-section. It is used with other section properties when checking strength, stiffness, detailing, and material quantities. Unit weight expresses the mass of the shape per unit length and supports estimating, handling, shipping, and framing coordination.
The source content identifies AISC 360-16, the AISC Specification for Structural Steel Buildings, as the governing reference context. The dimensions and values shown on this page should be read together with the applicable project specification, material requirements, connection design, and fabrication practices.
CAD and drafting use
The linked DWG resource can support layout and detailing workflows. Before using a downloaded drawing for fabrication or construction documentation, confirm its units, scale, layer standards, orientation, and geometry against the authoritative project information. Related references for W-shape dimensions, steel section terminology, and connection detailing can help with those checks.
W14x159 FAQ
What is W14x159?
W14x159 is the designation of a wide-flange structural steel shape. The page lists its section dimensions, cross-sectional area, unit weight, and a DWG reference.
What does the W designation mean?
The W designation identifies a wide-flange structural steel shape. The remaining designation distinguishes this shape within the W-shape reference system.
What information is provided for this shape?
The reference provides overall depth and width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
Can the DWG be used directly for fabrication?
The DWG is a drafting resource, not a substitute for project-issued drawings or engineering verification. Check the file’s units, scale, geometry, and revision status before incorporating it into documentation.
Does the listed unit weight determine design capacity?
No. Unit weight describes mass per unit length. Structural capacity also depends on the applicable material, limit state, loading, stability, connection behavior, and project-specific design checks.
