HE 200 B vs H-200x200x9x14

HE 200 B is an HE section from the European (Continental) range; H-200x200x9x14 is the closest equivalent in the European (Continental) range. HE 200 B carries more bending: 642 cm³ of plastic modulus against 617 cm³, 4.1% more. H-200x200x9x14 is the lighter of the two at 57.8 kg/m against 61.3 kg/m, a saving of 6.1% on steel weight. Both are about 202 mm deep, so either fits the same construction zone.

HE 200 B to EN 10365 · Continental Steel; H-200x200x9x14 to Continental Steel. Difference is expressed relative to H-200x200x9x14.

How to choose between them

On stiffness, HE 200 B has the larger second moment of area: 5,700 cm⁴ against 5,603 cm⁴, a difference of 1.7%. This matters more often than the strength comparison, because on normal floor spans deflection rather than bending capacity sets the beam size - so if the two are close on modulus but apart on inertia, the stiffer one is usually the better answer even when it is not the stronger one.

Measured as bending capacity per kilogram, the two are equally efficient (10.5 against 10.7 cm³ per kg/m), so on a pure steel-tonnage basis there is nothing to choose between them. The decision comes down to availability, connection detailing and what the rest of the frame uses.

In short, HE 200 B is the stronger section and H-200x200x9x14 is the lighter one; where those are the same section, it is the clear choice, and where they are not, decide on whether your design is governed by capacity or by tonnage.

Common questions

HE 200 B is the stronger of the two in bending, with a plastic modulus of 642 cm³ against 617 cm³ - 4.1% more. At the same steel grade that translates directly into moment capacity, since M_pl,Rd = W_pl x f_y / gamma_M0.

H-200x200x9x14 at 57.8 kg/m, against 61.3 kg/m for the other - a saving of 6.1%. Over a repeated floor beam that is a real cost difference, but check it against the deflection case before taking it.

Structurally it is the closest equivalent we hold: H-200x200x9x14 gives 617 cm³ of plastic modulus and 5,603 cm⁴ of inertia against 642 cm³ and 5,700 cm⁴. Re-check deflection and the connection details before swapping, since the flange and web thicknesses differ.

HE 200 B, with a second moment of area of 5,700 cm⁴ against 5,603 cm⁴ (1.7% more). Deflection under a uniform load goes as 5wL⁴/384EI, so it is inversely proportional to I - on a span where the deflection limit governs rather than strength, this is the number that decides the section.
