The W18x65 is a wide-flange structural steel shape listed here with metric dimensions and unit weight. This reference is intended for engineers, detailers, fabricators, and students who need a quick way to review the shape before moving to analysis, connection detailing, or drawing production.
Use the source data below as the controlling reference for the listed dimensions and properties. For broader context, compare this shape with other W-shape dimensions, review structural steel terminology, and consult the applicable AISC design and detailing guidance before using the section in a project.
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 : 467.4 mm
Width : 192.8 mm
Web Thickness : 11.4 mm
Flange Thickness : 19 mm
Root Fillet Radius : 10.2 mm
Sectional Area : 123.23 cm2
Unit Weight : 96.7 kg/m
How to read the W18x65 reference
The designation identifies a W beam, also called a wide-flange shape. The listed geometry describes the overall depth and flange width, together with the web and flange thicknesses. The root fillet radius is included because the transition between the web and flange affects drafting, detailing, and the way connected elements fit near the shape profile.
Dimensions and section properties
The source presents the shape in metric units, including depth, width, web thickness, flange thickness, sectional area, and unit weight. These values serve different purposes: geometry supports layout and detailing, sectional area is used in several section-property and material calculations, and unit weight supports estimating and handling considerations. They should not be treated as a substitute for project-specific strength, stability, serviceability, or connection checks.
When reviewing a steel shape, check whether the drawing or calculation uses the same unit system and whether the referenced section data matches the material and design basis selected for the project. Related resources on steel section properties, W-shape selection, and steel connection detailing can help place this entry in a larger workflow.
CAD and drafting use
The downloadable DWG reference can support preliminary drafting, section-profile coordination, and detail development. Confirm scale, units, layer conventions, and the required fabrication tolerances before incorporating the file into a project drawing. A CAD profile is a drafting aid; it does not replace a verified calculation model or fabrication review.
Referenced design standard
This entry refers to the American Institute of Steel Construction Specification for Structural Steel Buildings, identified in the source as AISC 360-16. The specification provides requirements related to the design, fabrication, and erection of steel structures in the United States. Always verify the governing contract documents and project requirements before relying on a standard reference.
W18x65 FAQ
What type of section is W18x65?
W18x65 is identified in the source as a W beam, commonly described as a wide-flange structural steel shape.
What information is provided for W18x65?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. The values are presented in metric units in the source content.
Can the listed dimensions be used directly for structural design?
They can support preliminary identification and coordination, but they are not a complete design check. Member strength, stability, connection behavior, material specification, loading, fabrication, and project requirements must be evaluated by a qualified engineer.
Is a DWG file available for this shape?
Yes. The source includes a downloadable DWG reference for W18x65. Review its units, scale, and drafting conventions before using it in project documentation.
Which standard is referenced on this page?
The source refers to AISC 360-16, the AISC Specification for Structural Steel Buildings identified there as the 2016 edition. Confirm the governing edition and project standard before design or fabrication work.
