The W30x191 is a wide-flange structural steel shape listed in the W-shape reference data. This page brings together its reported geometric dimensions, section area, unit weight, and a downloadable DWG file for drafting reference.
Use the source values for preliminary identification and coordination, then confirm applicable material, design, fabrication, and connection requirements through the project specifications and the responsible engineer. Related references include W-shape dimensions, steel section properties, and AISC 360-16 terminology.

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.

How to read the W30x191 reference
The listed dimensions describe the overall shape and its principal elements: depth, flange width, web thickness, flange thickness, and root fillet radius. Together, these values help engineers and detailers identify the section geometry and coordinate it with framing layouts, connection details, and fabrication drawings.
The reported sectional area is a geometric property of the cross-section, while the unit weight expresses the listed mass per unit length. These entries are useful for reference and estimating, but they do not by themselves establish a member’s design resistance, allowable load, buckling performance, or connection capacity.
AISC reference context
The source identifies the section with the American Institute of Steel Construction Specification for Structural Steel Buildings, referenced as AISC 360-16. That specification provides the broader framework for structural steel design, fabrication, and erection in the United States. Project-specific design still requires the applicable loads, restraints, material requirements, limit states, and connection details to be evaluated together.
DWG reference file
The downloadable DWG associated with this entry can support CAD coordination and drafting workflows. Treat the file as a reference for section identification and drawing development; verify units, insertion scale, layer conventions, and project requirements before using it in production documentation.
Frequently asked questions
What type of section is W30x191?
W30x191 is identified as a W-shape, commonly described as a wide-flange structural steel section. The source content provides its dimensional and reference properties.
What do the listed dimensions describe?
They describe the section depth, flange width, web and flange thicknesses, and root fillet radius. These are geometric identification values, not a complete structural design check.
Does the listed unit weight determine design capacity?
No. Unit weight is a mass-per-length reference. Member capacity depends on the complete design context, including loading, unbraced conditions, material requirements, limit states, and connections.
What is the DWG file used for?
The DWG file is provided as a CAD reference for drafting and coordination. Confirm scale, units, and project-specific detailing requirements before incorporating it into construction documents.
