The W30x90 is a W-shaped structural steel section identified by its nominal designation. This reference page presents the source dimensions and section data alongside practical guidance for interpreting the listed properties.
Use the information below for preliminary reference, drafting, and coordination. Final member selection, connection design, and structural verification should follow the applicable project requirements and be completed by 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.
Depth : 749.3 mm
Width : 264.2 mm
Web Thickness : 11.9 mm
Flange Thickness : 15.5 mm
Root Fillet Radius : 16.5 mm
Sectional Area : 169.68 cm2
Unit Weight : 133.2 kg/m
How to read the W30x90 reference data
The listed 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 top and bottom flange plates. These dimensions are useful when checking clearances, modeling the shape in CAD, and coordinating framing details.
The root fillet radius identifies the rounded transition between the web and each flange. That transition matters when developing accurate profiles, checking fit-up, or interpreting a manufacturer or section-shape drawing.
Sectional area and unit weight
Sectional area is a cross-sectional property used in calculations such as axial resistance, material quantity estimates, and related engineering checks. Unit weight expresses the mass of the section per unit length, which supports estimating shipping, handling, and steel tonnage. These values should be used with the complete design basis rather than as a substitute for member verification.
AISC reference and CAD workflow
The source identifies AISC 16 and the American Institute of Steel Construction Specification for Structural Steel Buildings. Treat that reference as the governing context for the supplied section information, while confirming project-specific material, design, fabrication, and erection requirements separately.
A DWG file is available through the download link in the source content. A useful workflow is to review the section dimensions first, import the drawing into the project template, and then confirm units, layer conventions, and detailing requirements before issuing drawings.
Frequently asked questions
What does W30x90 mean?
W30x90 is the designation used for this W-shaped structural steel section. The source content provides its dimensional and section-property data.
What is the web of a W section?
The web is the central vertical part of the shape. Its thickness is listed separately from the flange thickness because each component has a different role in the section’s geometry and engineering behavior.
What is the DWG download used for?
The DWG can support CAD modeling, drafting, layout coordination, and detail development. Before use in a project, verify the drawing units and compare the imported profile with the authoritative section data on this page.
Can this page replace structural design?
No. The page is a dimensional and drafting reference. Member selection, limit-state checks, connections, stability, fire requirements, and other project conditions require engineering review.
