The W12x87 reference provides the listed geometric and weight information for this W-shape, along with the applicable AISC 360-16 context and a CAD download. Use the source values as a starting point for section identification, drafting, and engineering review.
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 W12x87 reference
The depth and width describe the overall envelope of the section. Web thickness refers to the central vertical element, while flange thickness describes the thickness of the projecting top and bottom elements. These dimensions are useful when checking clearances, connection layouts, detailing space, and compatibility with other steel components.
The root fillet radius identifies the rounded transition between the web and each flange. This region affects how connected parts, plates, welds, and detailing tools interact with the rolled shape, so it should not be ignored when developing connection geometry or CAD details.
Area and unit weight
Sectional area represents the steel area through a cut perpendicular to the member’s longitudinal axis. Unit weight is useful for material takeoffs, shipping estimates, and preliminary framing comparisons. Final design decisions still require verification of the applicable material specification, loads, limit states, stability conditions, connections, and project requirements.
Reference standard and CAD workflow
The source identifies AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings, as the reference context for design, fabrication, and erection information. The available DWG file can support drafting and coordination, but users should verify the downloaded geometry against the authoritative project data before fabrication or construction.
