W33x130 is a wide-flange structural steel section listed in the W-shape data referenced to AISC 360-16. This page provides the profile dimensions, sectional area, unit weight, and a DWG resource for drafting and reference workflows.
Use the dimensional data below when reviewing steel framing layouts, connection details, fabrication drawings, or section-identification notes. For design work, verify the applicable material, loading, stability, connection, and specification requirements with the responsible engineer.

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.

Unit Weight : 194 kg/m
Understanding the W33x130 reference data
The listed depth and width describe the overall profile envelope. Web thickness identifies the thickness of the central web, while flange thickness identifies the thickness of the top and bottom flange elements. These dimensions are useful when coordinating member geometry with framing plans, connection clearances, detailing, and CAD drawings.
The root fillet radius describes the curved transition between the web and flange. This region affects how connected plates, bolts, welds, and detailing geometry are represented near the inside corners of the shape; it should not be treated as a sharp internal corner in a detailed drawing.
Area and unit-weight context
The listed sectional area is a cross-sectional property of the steel shape. The listed unit weight supports preliminary material takeoffs and self-weight estimation when combined with the member length. These values are reference data and do not, by themselves, establish allowable strength, deflection performance, connection capacity, or suitability for a particular structural application.
Using the DWG resource
The downloadable DWG can support drafting, layout coordination, and section-library development. Confirm the drawing scale, insertion units, layer conventions, and project drafting standards before incorporating the file into production documents. Related references may include W-shape terminology, steel section properties, connection detailing, and CAD block standards.
Frequently asked questions
What type of section is W33x130?
W33x130 is a W-shape, also commonly described as a wide-flange structural steel section.
What information is listed for W33x130?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
What does the root fillet radius represent?
It represents the curved transition where the web meets each flange. This geometry is important when preparing accurate connection and fabrication details.
Can the W33x130 data be used directly for structural design?
The listed values are reference information and should not be used as a complete design check. Structural design requires verification of the governing specification, material, loads, limit states, stability, connections, and project conditions.
Is a CAD file available?
Yes. The page includes a DWG download for W33x130. Review units and drafting conventions before using it in a project drawing.
