The W33x118 is a wide-flange structural steel shape identified by its nominal designation. This reference brings together the listed geometry, sectional area, unit weight, and a downloadable DWG resource for drafting and coordination.
Use the source values on this page as the dimensional reference for the shape. For related terminology, compare this entry with the site’s resources on W-shapes, steel section properties, and structural steel connections.
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.

Unit Weight : 175.7 kg/m
How to read the W33x118 listing
The dimensions describe the overall envelope and principal plate features of the section. Depth is the overall vertical dimension, while width describes the flange projection across the section. Web thickness and flange thickness identify the nominal thicknesses of the web and flanges listed in the reference.
The root fillet radius represents the curved transition between the web and flange. This detail matters when checking clearances, connection geometry, detailing assumptions, and compatibility with adjacent components. Fabrication and connection drawings should account for the actual shape profile rather than treating the intersection as a sharp corner.
Sectional area and unit weight
The listed sectional area is a cross-sectional property used in steel calculations and material takeoffs. The listed unit weight expresses the mass associated with a given length of the section. These values are related, but they should not be treated as a complete design check or as a substitute for the applicable material, stability, connection, and load-resistance calculations.
Design and drafting context
The source identifies AISC 360-16 as the referenced AISC specification for the design, fabrication, and erection of steel structures in the United States. Designers should confirm the governing project requirements, material specification, analysis assumptions, and connection conditions before using this shape in a structural design.
The attached DWG file can support CAD coordination and preliminary detailing. Before issuing drawings, verify the file against the authoritative dimensional listing and project drafting standards. Related internal references may include structural steel CAD blocks, steel connection detailing, and AISC shape terminology.
W33x118 FAQ
What does W33x118 mean?
W33x118 is a wide-flange, or W-shape, designation. The designation identifies the shape within the referenced structural steel section system; the page’s listed dimensions and properties provide the detailed reference.
What information is provided for the W33x118?
The listing provides depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. It also includes a DWG download for drafting and coordination.
Can the W33x118 be selected directly for a structural member?
No. Shape selection requires project-specific checks for loads, span, stability, material, limit states, connections, and applicable design requirements. The dimensional listing is a reference and does not establish design adequacy.
What is the DWG file used for?
The DWG file is intended to assist with CAD drafting, layout, and coordination. Confirm its geometry and layer or block conventions before incorporating it into an issued drawing set.
