Steel beam weight calculator
Pick the section from the range — IPE, INP, HEA or HEB — then enter length and quantity. Mass per metre is not computed from a formula: it is read from the standard's table, which is why the result agrees with what the stockholder will invoice.
Short answer
Beam weight is mass per metre from the table times the length. The sizes people ask for most: IPE 100 — 8.1 kg/m, IPE 160 — 15.8 kg/m, IPE 200 — 22.4 kg/m, IPE 300 — 42.2 kg/m, HEB 200 — 61.3 kg/m, HEA 200 — 42.3 kg/m. Multiplying dimensions by density does not work here: the section has root radii at the web-to-flange transition, and INP and UPN also have a tapered flange, so that sum is out by several per cent.

Rolling has tolerances: EN 10034 permits deviations in the section dimensions, and batch mass can differ from nominal by a few per cent. For invoicing and settlement the certified mass applies — the table is for design, first-pass costing and choosing lifting gear.
IPE, INP, HEA and HEB are the European range, the one held in stock across the EU and the UK. American W and S shapes to ASTM A6 are a different series with different proportions, and there is no size-for-size conversion between the two: a W 8×31 is not an HEB 200. For those, take the mass from the AISC tables instead.
IPE, INP, HEA, HEB — how they differ
IPE — a parallel-flange beam with a narrow flange. Width is roughly half the depth, the flanges are parallel, and the section is optimised for bending in one plane. This is the standard floor beam and portal rafter.
INP (normal beam) — the older shape, with the flange tapered 14 % on the inside. Still found in older structures and in rolled products outside the European standard. The sloping surface makes it awkward to seat a flat plate and calls for tapered washers under bolts.
HEA and HEB — wide-flange beams: flange width equals the depth or comes close to it. HEA is the light version, HEB the standard one, heavier and stiffer. They go into columns and anywhere load acts in two planes. Watch the numbering: HEA 200 is actually 190 mm deep, while HEB 200 is exactly 200 mm.
What this means at the torch
Flange thickness decides the procedure more than the section number does. On IPE 200 the flange is 8.5 mm — a fillet weld with no preparation, one or two runs. On HEB 200 it is 15 mm and on HEB 300 19 mm: now you need edge preparation, several runs and control of heat input, and for steel with a higher carbon equivalent also preheat.
The second point is mass. A 6 m HEB 300 weighs 700 kg — you do not turn that by hand or tack it on a single spot. The figure worked out above is at the same time your sling selection and a check on whether the wanted weld position can be held at all, or whether it has to be welded out of position.
The third is how much deposited metal the joint will take. Groove area and weld length are converted by the electrode consumption calculator, and the full cost per metre of weld including gas and labour by the weld cost calculator.
Frequently asked questions
How much does a 6 m IPE 200 beam weigh?
IPE 200 weighs 22.4 kg per metre, so a 6 m length comes to 134 kg. For comparison HEB 200 at the same depth weighs 61.3 kg/m — 368 kg over 6 m, nearly three times as much.
What is the difference between IPE and HEB at the same depth?
IPE has a narrow flange — width roughly half the depth — and works as a beam bent in one plane. HEB has a flange as wide as the section is deep and carries load in both directions, which is why it goes into columns. For welding the difference is real: the HEB 200 flange is 15 mm thick against 8.5 mm on IPE 200, so the first needs edge preparation and often preheat, the second does not.
Why does the table mass differ from the weighed mass?
Because the table gives the nominal value and the rolling mill works to tolerances: EN 10034 allows deviations in depth, width and flange thickness, and for a batch a mass deviation of a few per cent. Invoicing goes by the mass on the mill certificate, not by the table.
