The W12x336 is a wide-flange structural steel section listed with its principal dimensions, sectional area, and unit weight. This reference is intended to help engineers, detailers, fabricators, and students interpret the section data before using it in calculations or drawings.
Use the dimensional information below together with the applicable AISC Specification for Structural Steel Buildings. For broader comparison work, see related resources on W-shape dimensions, steel section properties, and structural steel terminology.
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 : 426.7 mm
Width : 340.4 mm
Web Thickness : 45.2 mm
Flange Thickness : 75.2 mm
Root Fillet Radius : 15 mm
Sectional Area : 638.06 cm2
Unit Weight : 500.9 kg/m
How to read the W12x336 reference
The listed depth describes the overall section depth, while the width describes the overall flange-to-flange dimension. The web thickness and flange thickness identify the thicknesses of the two principal parts of the rolled shape.
The root fillet radius describes the curved transition between the web and flange. This detail is important when interpreting drawings, checking clearances, and preparing connection or fabrication details.
The reference also reports sectional area and unit weight. Keep the stated units with these values when transferring them into calculation sheets, material takeoffs, or detailing software. Dimensions alone do not establish design adequacy; strength, stability, connection behavior, fabrication requirements, and project-specific criteria require engineering verification.
Standard and CAD reference
This page identifies AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings, as the referenced specification. The downloadable DWG can support drafting and coordination workflows, but users should verify scale, units, layer conventions, and project-specific detailing requirements before incorporating the file into production documents.

W12x336 FAQ
What information is provided for the W12x336?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
Which specification is associated with this reference?
The page refers to the American Institute of Steel Construction Specification for Structural Steel Buildings, identified here as AISC 360-16.
What is the DWG download used for?
The DWG is a CAD reference resource for viewing or developing drawings. Confirm the file’s units, scale, and project drafting requirements before using it in a final document.
Can the listed dimensions be used alone for structural design?
No. The dimensions and reported properties are reference data. Structural design requires review of the applicable specification, loads, limit states, connections, stability, and project requirements by a qualified engineer.
