Calculation formula
S = t × (A + B − t)
m₁ = S × 10⁻⁶ × ρ
Square S is given in mm², steel density ρ taken equal to 7850 kg/m³. Intermediate values are not rounded.
Inputs and units
A and B — leg widths in mm, t — thickness in mm, element length — in m, quantity — in pieces. Decimal values may be entered with a dot or comma.
Accuracy and Limitations
The model describes an idealized L-shaped section and does not include fillet radii, manufacturing tolerances and tabulated features of a specific product range. The result is a calculated geometric mass and does not replace verification against the product certificate.
