This free I-Beam and H-Beam Section Modulus Calculator helps you compute the bending strength of standard and custom I-beam profiles. Enter basic dimensions like flange height, web thickness, and flange width to get section modulus values around both X-X and Y-Y axes. Supports metric and imperial units.

Default values are based on standard IPE 360 beam: H = 360 mm, B = 170 mm, h = 12.7 mm, b = 8.0 mm.
Key Features
- 🔹 Dual Axis Output: Calculates Sxx (strong axis) and Syy (weak axis)
- 🔹 Flexible Unit Selection: Input in mm/inch, output in cm³/in³
- 🔹 Easy to Use: Just input four beam dimensions and get instant results
- 🔹 Responsive Design: Works smoothly on both desktop and mobile
- 🔹 Default Example Included: IPE 360 profile pre-filled for quick reference
How to Use
- Input the following values:
- H: Distance between flanges (inner height)
- B: Overall flange width
- h: Flange thickness
- b: Web thickness
- Select input and output units
- Click Calculate
- View calculated section modulus values for both axes below the button
Tip: You can change dimensions to simulate custom or standard I-beams.
