The W27x307 is a W-shape steel beam reference entry with dimensional and mass data presented from the listed AISC source. Use this page to review the section geometry, sectional area, unit weight, and available DWG resource before moving to detailed design or drafting work.
For related terminology, compare this entry with the site’s references for W-shapes, steel section properties, and structural steel connections. Those topics help explain how tabulated dimensions support modeling, detailing, and engineering calculations.
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.

Width : 365.8 mm
Web Thickness : 29.5 mm
Flange Thickness : 53.1 mm
Root Fillet Radius : 20.1 mm
Sectional Area : 581.93 cm2
Unit Weight : 456.8 kg/m
How to read the W27x307 reference data
The listed depth and width describe the overall envelope of the section. Web thickness identifies the thickness of the central web, while flange thickness describes the thickness of the top and bottom flange elements. The root fillet radius represents the rounded transition between the web and a flange; this detail matters when interpreting clear dimensions, contact conditions, and fabrication drawings.
Sectional area is a geometric property of the steel cross-section. It can be used with applicable material and design provisions when evaluating axial behavior or calculating other section properties, but it is not by itself a complete design check. The listed unit weight expresses mass per unit length. It is useful for estimating member dead load and material quantities, but it should not be treated as a beam capacity or allowable load.
Using the AISC and DWG references
The source identifies AISC 360-16 as the governing reference for the listed structural-steel information. Always confirm the applicable project requirements, material specification, limit states, connection design, stability conditions, and fabrication assumptions before using a section in a structure. This page is a dimensional reference, not a substitute for an engineered design.
The downloadable DWG file can support CAD layouts and preliminary detailing. Check the drawing units, layer conventions, section orientation, and project drafting standards before incorporating it into a production model. Related internal resources on DWG steel shapes, CAD detailing, and beam orientation can provide useful workflow context.
W27x307 FAQ
What type of steel section is W27x307?
W27x307 is identified here as a W-shape, commonly described as a wide-flange structural steel section. The source content provides its dimensional and mass information for reference.
What dimensions are listed for W27x307?
The entry lists overall depth, overall width, web thickness, flange thickness, and root fillet radius. These values describe the section’s basic geometry and should be read together with the applicable table or drawing conventions.
What does the unit weight represent?
Unit weight is the mass of the member per unit length as listed in the source. It can support dead-load and quantity estimates, but it does not establish structural capacity.
Is the W27x307 suitable for a particular beam design?
Not from the tabulated dimensions alone. Suitability depends on the project loads, span, bracing, support conditions, connection details, material requirements, applicable design checks, and engineering judgment.
Is a CAD file available for this section?
Yes. The source includes a DWG download for W27x307. Review the file’s units and drafting conventions before using it in a project model or fabrication document.
