Series overview
W27 series
The W27 series groups AISC W-family shapes that share the same nominal-depth designation prefix. Weights and actual depths still vary within the series, so use the table below to compare candidates before analysis.
The AISC W27 series contains 17 published sections ranging from 84.00 to 539.00 lb/ft . Actual depths range from 26.70 to 32.50 inches, despite the shared W27 nominal designation .
- Lightest W27
- W27X84
- Highest Ix
- W27X539
- Shallowest actual depth
- W27X84
- Widest flange
- W27X539

Questions & answers
W27 FAQs
What is the W27 series?
It is the set of published AISC W shapes whose designation begins with W27. Members share a nominal-depth label but can differ in weight, actual depth and properties.
Why do actual depths differ within W27?
The number in the designation is nominal. Published overall depth varies by weight. Always use the tabulated depth for clearance and detailing.
How should I choose among W27 weights?
Compare weight, Ix, Sx, flange geometry and project constraints, then analyze finalists under the same span and loads. There is no universal “best” section.
Can I analyze a W27 section in Optimal Beam?
Yes. Select a designation above and choose Analyze to load its properties into the beam calculator.
