How it was calculated
The weight is the section area multiplied by the material density:
kg/m ≈ t × (a + b − t) × 0.00785 plus the root radius correction, per EN 10056.For Angle 45×30×4, the section area is 2.87 cm², so 1 metre = 2.87 × 0.785 = 2.250 kg.
The real weight can differ by a few percent because of rolling tolerances. For other materials or lengths use the calculator.
