From designation to geometry

Reading the W27X307 record

The 27 in depth series in W27X307 is a designation. The tabulated depth d is 29.6 in and flange width bf is 14.4 in. The separately listed detailing depth ddet is 29.625 in.

The web thickness tw is 1.16 in and flange thickness tf is 2.09 in. Keep the exact designation with these dimensions: matching the depth series does not guarantee matching flanges, web geometry or connection fit.

Ix = 13,100 in⁴ and Iy = 1,050 in⁴ refer to the database x- and y-axes. Here Ix is numerically larger. Axis letters are labels, not a guarantee that x is always the larger axis. These are geometric properties, not allowable loads or complete member capacities.

Match the axis and dimension conventions to the figures in the AISC v16.0 workbook Readme. The profile above simplifies manufacturing geometry; its outline is not used to recalculate the published properties.

Worked quantity example

Nominal weight for W27X307

Assume 3 pieces, each 20 ft (6.096 m) long. This is a hypothetical quantity example, not a stock-length or lifting recommendation.

Using the published 307 lb/ft weight
Quantity	Calculation	Nominal pounds	Kilogram equivalent
One 20 ft piece	20 ft × 307 lb/ft	6,140 lb	2,785.057 kg
3 pieces	3 × 6,140 lb	18,420 lb	8,355.171 kg

Conversion: 1 lb = 0.45359237 kg; displayed results are rounded. This multiplication excludes connection plates, bolts, weld metal, coatings, cutting allowances and actual material variation. Use the material takeoff for your own lengths and quantities.

Shape family context

What is a wide-flange shape?

A W-shape is a hot-rolled, doubly symmetric wide-flange section commonly used for beams and columns. Its relatively wide flanges and web distribute material efficiently for many bending and axial-force applications.

Common context

Common project roles include floor beams, roof beams, girders, columns, transfer members, and parts of braced or moment frames.

Detailing watch

Confirm orientation, camber, flange and web connection access, unbraced length assumptions, copes, stiffeners, and the exact grade and availability required by the project.

Compare published reference values

W27X307 alongside nearby W records

These records share the same nominal series, outside envelope or leg arrangement, depending on the family. Peers are ordered by absolute weight difference, then listed depth and designation. The table does not rank structural performance or approve a substitution.

US customary values from the same AISC v16.0 dataset
Record	Weight (lb/ft)	Depth (in)	Area (in²)	Ix (in⁴)	Iy (in⁴)
W27X307 (this record)	307	29.6	90.2	13,100	1,050
W27X281	281	29.3	83.1	11,900	953
W27X336	336	30	99.2	14,600	1,180

Relative to W27X307, W27X281 changes nominal weight by -26 lb/ft, listed depth by -0.3 in, and area by -7.1 in². At the same hypothetical 20 ft length, the nominal weight difference is -520 lb.

Reference use only.

Data is derived from the AISC Shapes Database v16.0, consistent with the AISC Steel Construction Manual, 16th Edition, 1st Printing. AISC advises professional verification before use in a specific application. The downloadable DXF is a nominal reference profile and may simplify rolled fillets, flange tapers, angle radii, HSS corner radii, and other manufacturing geometry. Verify all dimensions and suitability before design, detailing, ordering, or fabrication.
