How to read the W21x147 reference
The designation W21x147 identifies a W, or wide-flange, structural steel shape. The source content reports the key geometric dimensions separately, including overall depth, flange width, web thickness, flange thickness, and root fillet radius. Reading these values together helps distinguish the section from other W-shapes and supports coordination between design calculations and drawings.
Why the listed properties matter
Sectional area is a cross-sectional property used in engineering checks and material takeoffs, while unit weight supports estimating, handling, and dead-load evaluation. The dimensional entries are useful for checking clearances, connection detailing, member orientation, and compatibility with surrounding components. They do not by themselves establish a member’s capacity or suitability for a particular structural application.
Using the DWG resource
The downloadable DWG can support CAD workflows such as layout, reference detailing, and drawing coordination. Treat downloaded geometry as a drafting aid: confirm orientation, units, project-specific detailing, and the governing design documents before issuing construction information.

Frequently asked questions
What is the W21x147?
It is a W, or wide-flange, structural steel shape identified by the designation W21x147. This page provides its reported dimensions, sectional area, unit weight, and a related DWG resource.
What information is provided for this shape?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight. The original source also identifies the AISC 16 reference.
Can these values be used to select a beam for a project?
They can support preliminary comparison and coordination, but final selection requires project-specific engineering review, including loading, span, stability, connections, material requirements, and applicable design provisions.
What is the DWG file used for?
The DWG is intended as a CAD reference for layout and detailing. Users should verify units, orientation, and project-specific requirements before relying on it in issued drawings.
