The W18x71 is a wide-flange structural steel shape identified by its W-shape designation. This reference summarizes the dimensional and unit-weight information provided in the source data and places it in the context of AISC-based steel documentation.
Use the listed dimensions when reviewing drawings, comparing steel shapes, or coordinating a model with a DWG reference file. For design work, confirm material specifications, load effects, connections, stability, and applicable project requirements through the responsible 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.
Depth : 469.9 mm
Width : 194.1 mm
Web Thickness : 12.6 mm
Flange Thickness : 20.6 mm
Root Fillet Radius : 10.2 mm
Sectional Area : 134.84 cm2
Unit Weight : 105.8 kg/m
How to read the W18x71 designation
A W-shape designation identifies a wide-flange section family and its weight designation in customary steel-shape references. The designation should be read together with the published geometric properties rather than used as a substitute for the complete section data.
What the listed dimensions describe
- Depth describes the overall section depth.
- Width describes the overall flange width.
- Web thickness describes the thickness of the central web.
- Flange thickness describes the thickness of the flanges.
- Root fillet radius describes the curved transition between the web and flange.
- Sectional area supports material and section-property calculations when used with the applicable design method.
- Unit weight supports estimating and detailing workflows; confirm the unit system before using it in a calculation.
AISC and drafting context
The source identifies AISC 16 and the AISC Specification for Structural Steel Buildings as the governing reference context. Review this entry alongside related resources on W shapes, steel section properties, structural steel terminology, and steel connection detailing. The downloadable DWG can support drawing coordination, but CAD geometry should be checked against the authoritative section data before fabrication or design use.
W18x71 FAQ
What type of shape is W18x71?
W18x71 is a wide-flange, or W-shape, structural steel section.
Which dimensions are provided for W18x71?
The source provides depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
What does the AISC 16 reference mean here?
It identifies the AISC Specification for Structural Steel Buildings, 2016 edition, as the reference context for the entry.
Is a DWG file available?
Yes. The source includes a DWG download for W18x71. Use the file as a drafting reference and verify geometry against the published section data before relying on it for technical work.
