The W12x35 is a W-shape, also called a wide-flange beam, identified by its nominal depth and weight designation. This page provides the published dimensional and mass information for the section, along with an engineering reference to the AISC specification and a downloadable DWG file.
Use the data below when reviewing steel beam dimensions, preparing drawings, or coordinating a preliminary framing layout. Final member selection, connection design, stability checks, and other structural decisions require verification by a qualified engineer using the governing project requirements.
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 : 166.6 mm
Web Thickness : 7.6 mm
Flange Thickness : 13.2 mm
Root Fillet Radius : 7.6 mm
Sectional Area : 66.45 cm2
Unit Weight : 52.2 kg/m
How to read the W12x35 reference
The designation helps distinguish this member from other W-shapes, while the listed dimensions describe its overall envelope and the thicknesses of its web and flanges. The root fillet is the curved transition between the web and flange and can matter when checking clearances, detailing, and fabrication interfaces.
Section properties and material takeoff
The sectional area is useful for understanding the steel quantity represented by the cross-section and for calculations that depend on area. The listed unit weight supports estimating member mass and material quantities. These values should be read together with the dimensional data rather than treated as a substitute for a complete design check.
Drafting and coordination use
The downloadable DWG can support drafting and model coordination. Confirm the drawing units, layer conventions, insertion point, and project standards before placing the shape in production documents. For related work, see the site’s references on W-shapes, steel section properties, structural steel connections, and CAD/DWG detailing.
Specification context
The source identifies AISC 360-16 as the reference specification for the design, fabrication, and erection of steel structures in the United States. A specification reference provides a design framework; it does not by itself establish that this member is adequate for a particular span, load, connection, or framing condition.
W12x35 FAQ
What does W12x35 mean?
“W” identifies a wide-flange structural shape. The remaining designation is the section’s nominal depth and weight classification used to distinguish it from other W-shapes.
What information is provided for this section?
The reference lists overall depth and width, web and flange thicknesses, root fillet radius, sectional area, and unit weight. It also identifies the AISC reference and provides a DWG download.
Can the W12x35 be selected directly for a structural project?
No. Member selection depends on loading, span, support conditions, lateral stability, connections, material specification, applicable building requirements, and other design checks. A qualified structural engineer should verify its use for the project.
