The W12x79 is a wide-flange structural steel shape listed in the AISC 16 W-shape reference. This page provides the source dimensions, cross-sectional area, unit weight, and a DWG resource for engineering and drafting workflows.
Use this entry alongside related W-shape dimensions, steel section properties, and AISC steel shape references when comparing members or preparing preliminary layouts. Final member selection and connection design require project-specific engineering verification.

How to use the W12x79 reference
The dimensional data identifies the overall depth and flange width of the section, while web thickness, flange thickness, and root fillet radius describe important aspects of its rolled profile. These values are useful when checking clearances, detailing connections, coordinating framing, and comparing this member with other W-shapes.
The listed sectional area supports calculations based on the steel cross section, while unit weight is useful for estimating member dead load and handling requirements. Keep the displayed units consistent when transferring values into analysis, estimating, or CAD workflows.
Reference and drafting resource
The source identifies AISC 16, including the AISC Specification for Structural Steel Buildings, as the governing reference associated with this listing. The downloadable DWG can support drafting and coordination, but CAD geometry should be checked against the authoritative dimensions before fabrication or construction use.
For broader comparisons, continue to the site’s W-shape reference pages and related steel terminology guides. Section dimensions alone do not establish allowable strength, stability, connection capacity, or suitability for a particular structural application.
