The W30x173 is a W-shape steel section reference for engineers, detailers, fabricators, and CAD users. The source data identifies its principal dimensions, sectional area, unit weight, and root fillet radius.
Use the values below as the controlling local reference for this shape. For design work, also confirm the applicable project specification, material requirements, connection details, and governing design checks.

Understanding the W30x173 reference
The W-shape designation is used for a wide-flange structural steel member. The listed depth and width describe the overall section envelope, while web thickness and flange thickness help define the proportions of the rolled shape. The root fillet radius describes the transition between the web and flange and may be important when preparing connection or detailing clearances.
Sectional area and unit weight
Sectional area is used in calculations involving the steel cross-section, including member mass and certain design checks. Unit weight expresses the mass of the section per unit length and is useful for estimating steel quantities, shipping loads, handling requirements, and framing dead load. Do not substitute a generalized weight for the value listed in the source reference.
Using the DWG reference
The downloadable DWG can support drafting and coordination workflows. Treat CAD geometry as a reference rather than a replacement for the published section data, fabrication documents, or project-specific detailing requirements. Check units, drawing scale, layer conventions, and the fit of the shape at connections before issuing drawings.

For broader reference work, compare this entry with other W-shape dimensions, review steel section properties, and consult resources covering structural steel connections, steel detailing, and CAD/DWG standards. These related topics help connect the tabulated shape data to practical design and drafting decisions.
W30x173 frequently asked questions
What type of section is W30x173?
W30x173 is identified as a W-shape, commonly described as a wide-flange structural steel section. Its exact geometry is defined by the dimensions listed in the source reference.
What information is provided for W30x173?
The reference provides depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. It also identifies the AISC 16 reference and provides a DWG download.
Can the W30x173 data be used directly for structural design?
The listed values are useful reference data, but they are not a complete design. Member strength, stability, connections, loads, serviceability, material, fabrication, and project requirements must be evaluated by a qualified engineer using the applicable specifications.
What is the W30x173 DWG used for?
The DWG is intended to assist with CAD drafting, layout, and coordination. Verify the drawing against the source dimensions and project requirements before using it in issued construction documents.
