    Steel Section Database

    Search the rolled W-shape table by depth and weight, and read the properties the member checks use. Every value comes from the AISC Shapes Database converted to SI, so a shape found here is one the AISC check can run on.

    engineering methodology

    A clear path from inputs to results.

    Search the rolled W-shape table by depth and weight, and read the properties the member checks use. Every value comes from the AISC Shapes Database converted to SI, so a shape found here is one the AISC check can run on.

    Step-by-step methodWorked exampleAssumptions explained

    How to use

    1. Set minimum depth (mm).
    2. Set maximum depth (mm).
    3. Set maximum area (mm²).
    4. Read the headline metrics, then check the table for the detail.

    The formula

    m=A⋅7850/106m = A · 7850 / 10⁶

    Reference: AISC Shapes Database v15.0, converted to SI; curated doubly-symmetric W-shapes.

      Sections in range: 7 · Lightest: W8x31 · Deepest: W18x50 · Range of area: 5890–9484 mm²

    Result

    Sections in range: 7 · Lightest: W8x31 · Deepest: W18x50

    Interpreting the result

    7 sections fall between 200 and 500 mm deep under 1.500e+4 mm².

    Assumptions & limitations

    • Curated subset of W-shapes, not the full AISC catalogue.
    • Values converted from US customary with exact factors.

    Frequently asked questions

    Where do the numbers come from?

    The AISC Shapes Database v15.0, converted to SI — nothing on the page is estimated.

    Can I run a member check on a section found here?

    Yes; the member checks read the same table, so the designations match.
