I Beam Weight Calculator
Our handy I-beam weight calculator makes it quick and easy to calculate the per foot, per meter, or total weight of I-beams in both sloped and parallel-flanged forms.
For guidance on how to use the calculator, please refer to the user guide below the calculator. We’ve also included a step-by-step tutorial if you’d prefer to calculate the weight an I-beam manually, along with handy weight charts for both IPE and IPN type beams.
How to Use the I-Beam Weight Calculator
The first step is to choose the type of I-beam you want to calculate the weight of, with either ‘sloped flange’ or ‘parallel flange’ options being available.
- Next, you need to choose the material used for the I-beam(s) in your calculation, and you can choose this via the ‘I Beam Material’ dropdown in box (2).
You can change how many I-beams you include in your calculation by updating the ‘Quantity’ input in box (2).
The ‘Density’ box will automatically be populated based on the material type you choose.
You can update the ‘Density’ figure to a different value if needed, although we’ve based the figure used for each material on industry guidance.
You’ll need to enter various dimensions for your calculation including ‘Length’, ‘Width’, ‘Height’, ‘Web Thickness’, ‘Flange Thickness’, and one or two ‘Radius’ values depending upon your choice of I-Beam profile.
You can select the relevant units for each measurement using the ‘Unit’ dropdowns, including millimeters, centimeters, meters, inches, and feet.
- Use the ‘Calculate’ button to complete your calculation, or the ‘Reset’ button to reset the I-beam weight calculator if you want to start over.
How to Calculate I-Beam Weight
Here’s how to manually calculate the weight of an I-beam if you’d prefer to bypass the calculator above:
How to Calculate the Weight of a Parallel-Flanged I-Beam
You’ll first need to calculate the volume of the parallel-flanged I-beam, and you can do so via the following equation:
The above H beam weight formula consists of the following elements:
To demonstrate the above equations in action, we’ll work through an example of a mild steel (i.e. carbon steel) I-beam with the following dimensions:
- Length – 3000mm
- Height – 300mm
- Width – 150mm
- Web Thickness – 7.1mm
- Flange Thickness – 10.7mm
- Internal Radius – 15.0mm
As we’ll be using a density of 7850kg/m3 for the mild steel in our calculation, we’ll need to convert the above dimensions to meters. The length becomes 3.0m, the height is 0.3m, the width is 0.15m, the web thickness is 0.0071m, the flange thickness is 0.0107m, and the internal radius is 0.015m for the calculation.
Here’s an overview of how the I-beam volume calculation works using the dimensions in this example:
V1 = (0.15 x 0.0107 x 3.0) x 2
V1 = 0.00963m3
V2 = (0.3 – (2 x 0.0107)) x 0.0071 x 3.0
V2 = 0.00593418m3
V3 = ((0.015 x 2)2 – (3.142 x 0.0152)) x 3.0
V3 = 0.00057915m3
Overall Volume = 0.00963m3 + 0.00593418m3 + 0.00057915m3
Overall Volume = 0.01614333m3
Mild Steel Density = 7850 kg/m3
If we multiply the 0.0076m3 volume figure by the 7850 kg/m3 density figure, we end up with a weight of 126.73 kg or 279.38 lbs.
IPE vs IPN Beams – What’s the Difference?
There are two common European standard I-beam types, including IPE and IPN.
IPN (or INP as is often used) is the designation given to I-beams with sloped internal flanges. As with IPE beams, IPN beams are available in dimensions specified in EN 10365. However, the product tolerances of IPN beams is specified in EN 10024:1995.
IPE and IPN beams are typically manufactured using steel grades of S235JR, S275JR/J0, and S355JR/J2, but other grades can be used.
Standard beam lengths include 6000mm, 6100mm, 12000mm, and 12100mm. However, many manufacturers can offer these beams in custom sizes.
Here’s an overview of the weight and dimensional information for each cross section type:
