The W12x72 page identifies a W beam and presents its principal dimensional and mass data for quick reference. The listed values are the local source data for this section and should be read together with the applicable project specifications and design requirements.
Use this reference when checking steel section dimensions, preparing drawings, or comparing W-shape information. For broader context, see related resources on W-shape terminology, steel section properties, and AISC steel design references.
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 : 312.4 mm
Width : 304.8 mm
Web Thickness : 10.9 mm
Flange Thickness : 17 mm
Root Fillet Radius : 15.2 mm
Sectional Area : 136.13 cm2
Unit Weight : 106.9 kg/m
How to read the W12x72 reference
The dimensional entries describe the overall depth and width of the member, along with the web thickness, flange thickness, and root fillet radius. These features affect detailing, connection clearances, fit-up, and how the section is represented in structural drawings.
The listed sectional area describes the amount of steel in the cross-section, while unit weight expresses the member’s mass per unit length. These values are useful for material takeoffs and preliminary comparisons, but they do not replace the complete section-property data and design checks required for an engineering application.
Design and drafting considerations
- Confirm units before transferring dimensions into calculations, fabrication documents, or CAD files.
- Check the flange, web, and root-region dimensions when reviewing connection details or modeling interfaces.
- Use the cited AISC specification context alongside project criteria, material requirements, connection design, stability checks, and applicable engineering review.
- Download the provided DWG when a compatible CAD reference is needed, then verify drawing scale, layer settings, and project-specific detailing requirements.
The DWG resource is a drafting aid rather than a substitute for verified design documents. Related internal references may include W-beam naming, structural steel connections, CAD and DWG resources, and steel quantity takeoff guidance.
W12x72 FAQ
What type of section is W12x72?
The source identifies W12x72 as a W beam. The page provides its principal dimensions, sectional area, and unit weight for reference.
What information is provided for W12x72?
The reference lists depth, width, web thickness, flange thickness, root fillet radius, sectional area, and unit weight.
Can these values be used by themselves for structural design?
No. The listed values are reference data and do not constitute a complete design check. An engineer must confirm the required section properties, material specification, loading, stability, connection behavior, applicable project criteria, and construction requirements.
What is the AISC reference on this page?
The page points to AISC 360-16, the AISC Specification for Structural Steel Buildings identified in the source content. Always confirm which requirements govern the specific project.
What is the DWG download used for?
The provided DWG can support CAD coordination and drafting workflows. Review the file before use and verify its dimensions and detailing against the authoritative project information.
