Angle Weight Calculator
This calculator estimates the mass of a metal angle section. It uses leg sizes, thickness, length, density, quantity, waste allowance, and gravity.
Plotly Graph
The graph shows how the weight of one angle piece changes with length. It updates after each calculation.

Formula Used
Cross-sectional area: A = t × (L₁ + L₂ − t)
Here, t is thickness, L₁ is Leg A, and L₂ is Leg B.
Volume per piece: V = A × Length
Mass per piece: m = V × ρ
Total mass before waste: M = m × Quantity
Total mass after waste: Mfinal = M × (1 + Waste/100)
Weight force: F = Mfinal × g
This model assumes a sharp-cornered angle section. Rounded roots and manufacturing tolerances can slightly change the actual value.

Frequently Asked Questions
1. What does this calculator estimate?
It estimates the mass of an angle section from leg sizes, thickness, length, density, quantity, and waste allowance. It also shows volume and gravitational force.
2. Does it work for unequal angle sections?
Yes. Leg A and Leg B can be different. That makes it suitable for both equal and unequal angle profiles.
3. Why is density important?
Density connects volume to mass. A steel angle and an aluminum angle with the same dimensions will have different weights because their densities differ.
4. What is waste allowance used for?
Waste allowance adds extra mass for cutting loss, trimming, handling, or procurement margin. It helps produce a safer estimate for purchasing.
5. Is the formula exact for every angle section?
It is a practical estimating formula. Real sections can include root radii, rounded corners, and tolerance effects that slightly change the final mass.
6. What is the force result?
The force result is gravitational force. It is calculated by multiplying the final mass by the selected gravity value.
7. Can I use custom materials?
Yes. Select Custom Density and enter your own value in kg/m³. This supports special alloys and nonstandard materials.
8. What do the CSV and PDF downloads contain?
They include the current calculation summary. The PDF also includes the example table so you can share a compact reference report.
