The W18x76 is a W-shaped structural steel section identified in the source data with metric dimensions, sectional area, and unit weight. This reference is intended to help engineers, detailers, fabricators, and students interpret the listed shape information before using it in drawings or design workflows.
The data below identifies the section geometry and mass properties associated with this shape. Use the dimensional information alongside the applicable project specifications, material requirements, connection details, and engineering checks. The page also includes a DWG resource for CAD and detailing work.
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.
Depth : 462.3 mm
Width : 279.4 mm
Web Thickness : 10.8 mm
Flange Thickness : 17.3 mm
Root Fillet Radius : 10.2 mm
Sectional Area : 143.87 cm2
Unit Weight : 112.9 kg/m
How to read the W18x76 reference
The listed depth and width describe the overall profile envelope. Web thickness refers to the thickness of the central web, while flange thickness describes the thickness of the flanges. The root fillet radius identifies the curved transition between the web and flange; this feature matters when matching the physical profile in fabrication or detailing work.
Sectional area is a geometric property used in steel calculations, while unit weight expresses the mass of the section per unit length. These values should be kept with their stated units when preparing material takeoffs, checking member data, or coordinating structural drawings.
Reference and CAD workflow
The source identifies AISC 360-16, the AISC Specification for Structural Steel Buildings, as the governing reference for the listed shape information. AISC requirements address the design, fabrication, and erection of steel structures; project-specific design decisions still require the applicable material specification, load criteria, detailing requirements, and engineering review.
For drafting and coordination, download the supplied W18x76 DWG and verify its orientation, units, layer conventions, and insertion scale before incorporating it into a project file. Related site resources on W-shapes, steel section properties, structural steel terminology, and CAD/DWG detailing can provide useful context when reviewing this shape.
W18x76 FAQ
What type of section is W18x76?
W18x76 is a W-shaped structural steel section. The source provides its overall dimensions, thicknesses, root fillet radius, sectional area, and unit weight.
What dimensional information is listed for W18x76?
The reference lists depth, width, web thickness, flange thickness, and root fillet radius. These values describe the section geometry and should be read with the units shown in the source.
What does the sectional area represent?
Sectional area is the cross-sectional geometric area of the steel profile. It is distinct from unit weight and should not be treated as a substitute for a complete structural design check.
Where can I get a W18x76 CAD file?
The source includes a DWG download for W18x76. Before using it, confirm the drawing units, scale, orientation, and project drafting standards.
Which reference is identified for this shape?
The source refers to AISC 16 and identifies AISC 360-16, the 2016 edition of the AISC Specification for Structural Steel Buildings.
