How do you calculate I-beam weight?

Find the cross-section area = 2 × (bf × tf) + (d − 2 × tf) × tw, multiply by the beam length to get volume, then multiply volume by the bronze density (8.73 g/cm³) for the weight. Convert to kilograms, pounds, or metric tons as needed.

What density is used for bronze?

The calculator uses 8.73 g/cm³, which is the density of common commercial bronze (Cu-Sn alloy, approximately 90% copper and 10% tin). Other bronze alloys may vary slightly (8.2–8.9 g/cm³).

What is the cross-section area formula for an I-beam?

Area = 2 × (bf × tf) + (d − 2 × tf) × tw, where bf is flange width, tf is flange thickness, d is total height, and tw is web thickness.

Can I use this for aluminum bronze or other alloys?

This tool is calibrated for commercial bronze at 8.73 g/cm³. For other alloys, the result will be an approximation. Consult material data sheets for exact density values.

Why does my I-beam have two flanges?

A standard I-beam has a top flange, a bottom flange, and a connecting web. The formula accounts for both flanges and the web between them.

What units can I use for input?

You can enter dimensions in millimeters or inches. Select the unit before entering values; the tool converts internally before applying the bronze density in g/cm³.
