The W27x217 is a W-shaped structural steel beam identified by its nominal designation. This reference provides the listed dimensions and section data from the local AISC-based source, along with a DWG resource for drafting and coordination.
Use the dimensional data to understand the overall envelope, web and flange geometry, and the section’s reported mass and area. For design work, verify material requirements, loading, stability, connections, and applicable project criteria with the governing specifications and 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.

Sectional Area : 412.26 cm2
Unit Weight : 323.6 kg/m
How to read the W27x217 reference
Depth and width describe the overall section envelope. These values are useful when checking framing clearances, connection layouts, detailing space, and coordination with adjacent members. They should not be treated as a substitute for the authoritative section data in the source.
The web thickness describes the central vertical element, while flange thickness describes the thickness of the top and bottom flange regions. The listed root fillet radius identifies the curved transition between web and flange. This transition matters when modeling contact surfaces, coping, plates, seats, and connection details.
Section area and unit weight
The reported sectional area is a geometric property of the steel cross-section. The listed unit weight supports material quantity estimates and coordination, but final takeoffs should account for the project’s detailing conventions, splices, plates, and other connected steel.
Design and drafting use
The source identifies AISC 360-16 as the reference for structural steel design, fabrication, and erection requirements. Consult the applicable AISC provisions and project documents before using this shape in a design. The downloadable DWG can support layout and drafting workflows; confirm units, scale, layer settings, and geometry against the published section data before issuing drawings.

W27x217 FAQ
What does W27x217 mean?
W27x217 is the designation for a W-shaped structural steel beam. The designation identifies the section series and its nominal size and weight classification; use the published dimensions on this page for the actual section geometry.
What do the web and flange dimensions describe?
The web dimension describes the thickness of the central web, and the flange dimension describes the thickness of each flange region. These values help with detailing, connection fit-up, modeling, and clearance checks.
What is the root fillet radius used for?
The root fillet radius describes the curved transition between the web and flange. It is important when detailing plates, seats, copes, weld access, and other components that interface with the rolled section.
Can the W27x217 be selected directly for a structural design?
No. Shape dimensions alone do not establish whether a member is adequate. Selection requires engineering checks for the applicable loads, limit states, stability, connections, materials, and project requirements.
Is a DWG available for the W27x217?
Yes. The source includes a DWG download for the W27x217. Check the drawing units and geometry against the reference data before using it in production documentation.
