The W18x234 is a wide-flange structural steel beam designation listed in the SteelSTD W-shape reference. This page provides the section dimensions and basic identification data needed for preliminary reference, drafting, and coordination.
Use the source values below together with the applicable project specifications and engineering checks. For related information, see the site’s references on W-shape dimensions, steel section properties, AISC terminology, and structural steel CAD resources.
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 : 535.9 mm
Width : 297.2 mm
Web Thickness : 29.5 mm
Flange Thickness : 53.6 mm
Root Fillet Radius : 10.2 mm
Sectional Area : 442.58 cm2
Unit Weight : 347.4 kg/m
How to read the W18x234 reference
The listed depth and width describe the overall profile dimensions. Web thickness identifies the thickness of the central web, while flange thickness identifies the thickness of the top and bottom flange material. The root fillet radius describes the curved transition between the web and each flange.
Sectional area is a cross-sectional property used in calculations such as axial resistance, mass estimation, and section-property review. Unit weight expresses the listed mass per unit length. It should not be treated as an allowable structural load without applying the appropriate material, loading, stability, connection, and design requirements.
Reference and drafting use
The source identifies AISC 360-16 as the governing reference associated with this listing. The dimensions can help with layout and clearance coordination, while the downloadable DWG can support drafting workflows. Confirm the CAD file, units, tolerances, material specification, and fabrication requirements against the project documents before using them for fabrication or final design.
Because section behavior depends on the complete design condition, engineers should verify strength, stability, serviceability, connections, and applicable local requirements rather than selecting a member from dimensions alone.
W18x234 FAQ
What type of section is W18x234?
W18x234 is identified on this page as a W beam, also called a wide-flange beam in common U.S. structural steel terminology.
What information is listed for W18x234?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. These values are provided in the source content in millimeters, square centimeters, and kilograms per meter as labeled.
Which specification is referenced?
The page refers to the American Institute of Steel Construction Specification for Structural Steel Buildings, identified in the source as AISC 360-16.
Is the W18x234 automatically appropriate for a project?
No. The listed dimensions and properties are reference data, not a completed member selection. Final use requires project-specific engineering review of loads, support conditions, stability, connections, material requirements, and applicable design provisions.
Is a CAD file available?
Yes. The source includes a DWG download for W18x234. Review the drawing and confirm its units and geometry before incorporating it into project documentation.
