The W6x9 is a W-shape steel section referenced in the AISC shape data used on this page. This reference provides the section dimensions, cross-sectional area, unit weight, and a downloadable DWG file for drafting workflows.
Use the listed properties as a starting point for coordination, detailing, estimating, and preliminary engineering review. Final member selection and connection decisions require verification against the applicable design criteria, material specifications, loading, and project conditions.

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.

Width : 100.1 mm
Web Thickness : 4.3 mm
Flange Thickness : 5.5 mm
Root Fillet Radius : 6.4 mm
Sectional Area : 17.29 cm2
Unit Weight : 13.6 kg/m
How to read the W6x9 reference
The dimensional entries describe the overall depth and flange width of the section, together with the web and flange thicknesses. The root fillet radius identifies the curved transition between the web and flange. These details are important when checking clearances, preparing connection details, and coordinating the section with plates, bolts, welds, or adjacent members.
The sectional area is used in calculations involving axial resistance, self-weight, and other section-based engineering checks. The unit weight is useful for preliminary material takeoffs, shipping estimates, and dead-load calculations. It should be applied consistently with the units used elsewhere in a project.
Drafting and design workflow
Before using the W6x9 in a model or detail, confirm the section orientation and verify that the drawing scale, units, and reference geometry match the project standard. The downloadable DWG can support CAD coordination, but a drawing file does not replace an engineer-reviewed design or a project-specific fabrication detail.
For related research, compare this entry with other W-shape steel sections, review explanations of section properties, and consult resources covering steel connections and detailing. These topics help connect tabulated dimensions with practical drafting and structural-engineering decisions.
Frequently asked questions
What information is provided for the W6x9?
The reference lists the section depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. It also provides a DWG download for CAD reference.
What does the W in W6x9 indicate?
The W identifies the section as a wide-flange, or W-shape, steel member. The complete designation should be used when selecting the section so it is not confused with another steel shape.
Why do web and flange thickness matter?
Web and flange thickness affect detailing clearances, connection geometry, local behavior, fabrication considerations, and the engineering properties used in design checks. The listed values should be used rather than estimated from the designation.
Can the DWG file be used as a final design document?
No. The DWG is a drafting reference. Engineers and detailers should verify dimensions, orientation, units, material requirements, and project-specific connection details before issuing design or fabrication documents.
Which reference is associated with this page?
The source identifies AISC 360-16, the AISC Specification for Structural Steel Buildings, as the governing reference for the presented shape information.
