PUTTING IT INTO PRACTICE
Angle Bar Weight: a worked example
The values below are an illustrative example, not a recommendation. Replace them with measurements or assumptions that match your question.
| Input | Example value |
|---|---|
| First outside leg (mm) | 50 |
| Second outside leg (mm) | 50 |
| Thickness (mm) | 5 |
| Length (m) | 2 |
| Density (kg/m³) | 7,850 |
| Result | 7.4575 kg |
- Check the input labels and enter the example values above.
- Apply the relationship: Area = thickness × (leg one+leg two−thickness); mass = area × length × density.
- The result is 7.4575 kg, rounded for display.
How to interpret your result
Ideal sharp corners; real rolled-angle fillets and tolerances change mass.
Use actual dimensions and a density matching the material and condition. Rolled sections, corners and manufacturing tolerance can differ from sharp ideal geometry. Weight estimates do not establish structural capacity.
Frequently asked questions
Should nominal or actual material dimensions be used?
Use actual dimensions for a geometric mass estimate. Nominal product labels and finished dimensions can differ.
When is the angle bar weight calculator useful?
Estimate mass of an ideal equal- or unequal-leg angle section. Ideal sharp corners; real rolled-angle fillets and tolerances change mass.
How do I use the angle bar weight calculator?
Enter first outside leg (mm), second outside leg (mm), thickness (mm), length (m), density (kg/m³). The result updates automatically. Use the units shown beside each input; the example values illustrate the method.
Which formula does this calculator use?
Area = thickness × (leg one+leg two−thickness); mass = area × length × density.
What should I check before using the result?
Ideal sharp corners; real rolled-angle fillets and tolerances change mass.
How are results rounded?
Scalar numbers display up to six decimal places, with scientific notation for very large or small values. Text, fraction, date and schedule outputs use the format described on the tool. Intermediate calculations use JavaScript floating-point arithmetic. Keep sensible precision for your measurements.
