Stiffness and strength per kilogram
The elastic section modulus Zx governs bending strength. Dividing it by the weight shows how efficiently each size uses its steel: higher is better when weight is the cost driver.

How the weight is calculated
Mass per metre = cross-sectional area × density of steel = 53.81 cm² × 0.785 kg/(cm²·m) = 42.24 kg/m.
Rolled sections are made to a nominal mass, and the actual mass can differ by a few percent within the tolerances of EN 10034 (I and H sections) or EN 10279 (channels). For purchasing, invoicing by weight or checking deliveries, use the producer's stated mass.
Typical uses
Beams of this shape are used as floor and roof beams, lintels, crane girders and frame members, where bending about the strong axis governs.
