The W10x100 is a W-shape steel section identified by its nominal designation. This page provides a practical reference for interpreting the section dimensions and other values listed in the local AISC-based data.
Use this information alongside related resources on W-shape terminology, steel section properties, and structural steel detailing. The listed dimensions and properties are reference data; final member selection, connection design, stability checks, and detailing should be verified by a qualified engineer for the applicable project requirements.
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.

How to read the W10x100 reference
The designation identifies the section family and its nominal size and weight classification. The source content identifies this member as a W Beam and references the AISC Specification for Structural Steel Buildings, AISC 360-16, which addresses the design, fabrication, and erection of steel structures in the United States.
Dimensions and shape terminology
Depth describes the overall vertical extent of the rolled section, while width describes the flange extent across the section. Web thickness refers to the thickness of the central web, and flange thickness refers to the thickness of the horizontal flange elements. The root fillet radius describes the curved transition between the web and flange. These details are important when checking clearances, connection layouts, copes, and drafting geometry.
Area and unit weight
Sectional area is a geometric property used in calculations such as axial resistance and mass estimation. Unit weight, reported in the source as mass per unit length, helps with material takeoffs, shipping estimates, and dead-load calculations. It should not be treated as a complete design load without considering the full structural system and applicable loading requirements.
DWG reference and drafting use
The downloadable DWG file can support CAD layout, preliminary detailing, and coordination workflows. Before using imported geometry for fabrication or final detailing, check units, layer conventions, insertion scale, end conditions, and any project-specific drafting requirements. Related internal references on CAD/DWG steel shapes, steel connections, and section property terminology can help place this profile in a broader workflow.
W10x100 FAQ
What type of section is the W10x100?
The W10x100 is identified in the source as a W Beam, a wide-flange structural steel section.
Which specification is referenced for this profile?
The source references AISC 360-16, the AISC Specification for Structural Steel Buildings. The reference provides the stated U.S. design, fabrication, and erection context, but it does not replace project-specific engineering review.
What do the listed dimensions describe?
The listed dimensions describe the section depth, flange width, web thickness, flange thickness, and root fillet radius. Together, they help users understand the physical rolled shape for analysis, detailing, and CAD coordination.
What is the difference between sectional area and unit weight?
Sectional area is a geometric measure of the steel cross-section. Unit weight expresses the member’s mass per unit length. They serve different purposes and should not be substituted for one another in calculations.
Is the DWG file ready for fabrication?
The DWG is a drafting reference and should be checked against the project’s units, detailing standards, connection requirements, and approved engineering documents before fabrication use.
