Steel profile weight calculator (H-beam & I-beam)
This tool gives the weight of a standard structural steel section, an H-beam (HEA, HEB, HEM) or an I-beam (IPE, IPN), or a UPN channel, before you order or lift it. Pick the profile series, choose the size, enter the length, and it returns the weight of one length, the total for your quantity, and the price if you add a rate per kilo. It is made for steel fabricators, structural engineers, estimators and buyers who work with named rolled sections every day.
The figures are the published mass-per-metre values from the EN and DIN standards, so the result matches a steel catalogue rather than a rough estimate. The mass per metre used is shown with every result so you can verify it at a glance.
How to calculate steel profile weight
- Choose the Profile series, for example HEB or IPE.
- Pick the Size from the list, for example 200 or 300.
- Enter the Length and its unit (millimetres, centimetres or metres). Metres is the default, since profiles are sold by the metre.
- Set the Quantity for more than one length.
- Read the weight in kilograms and pounds. Add a price per kg to also get the total cost.
The weight of one section is simply its mass per metre multiplied by the length: weight (kg) = mass per metre (kg/m) × length (m). The size list updates to match the series you pick, so you only ever see valid sections.

These are the nominal masses per metre used by the calculator. The tool covers every size up to 1000 mm; the most common structural sizes are listed here.
H-beam weight per metre — HEA, HEB, HEM

IPN, HEM and UPN channels are in the calculator too; pick the series to see its full size list.
H-beam vs I-beam: which is heavier?
For the same nominal size, an H-beam is heavier than an I-beam because its flanges are wider. An HEB 200 is 61.3 kg/m and an HEA 200 is 42.3 kg/m, while an IPE 200 is only 22.4 kg/m. So when a drawing says “H 200” it usually means an HEA or HEB, and it will weigh two to three times a same-depth IPE. If you are estimating, confirm whether the section is HEA, HEB or IPE before you price it.
Worked example
A 6 m length of HEB 300 has a mass per metre of 117 kg/m, so it weighs 117 × 6 = 702 kg. Ten of them come to 7,020 kg (about 15,480 lb). Add a price per kilo in the tool to turn that weight into a cost.
Why use this calculator
It is free, instant and private, running entirely in your browser with no sign-up and no upload. It keeps the common European beam and channel series in one place, serves both kilograms and pounds at once, and because it uses standard nominal masses, the numbers line up with what your supplier quotes.
Tip: for sheet, plate, round bar, hexagonal bar, flat bar, square bar, tube, pipe or angle, or for any cut or custom size, use the metal weight calculator, which works straight from the dimensions.
Frequently asked questions
- How does the steel profile weight calculator work?
- Each standard section has a published nominal mass per metre defined by the EN and DIN standards. You choose the series (such as HEB), the size (such as 300), and a length, and the tool multiplies the mass per metre by the length, then by the quantity. It also shows the mass per metre it used so you can check it against a catalogue.
- Which profile series are included?
- IPE and IPN (I-beams), HEA, HEB and HEM (wide-flange H-beams, also called HE-A, HE-B, HE-M or IPBl, IPB, IPBv), and UPN channels. These are the European hot-rolled sections used across Turkey and continental Europe.
- What is the difference between an H-beam and an I-beam?
- Both are I-shaped, but H-beams (HEA, HEB, HEM) have wider, parallel flanges and are close to as wide as they are deep, so they carry more load and weigh more for the same depth. I-beams (IPE, IPN) are narrower and taller. For the same nominal size an HEB is heavier than an HEA, and both are heavier than an IPE.
- Where do the weights come from and how accurate are they?
- They are the official nominal masses per metre from EN 10025, EN 10034, DIN 1025 and DIN 1026, not a geometric estimate. That matters because rolled sections have root fillets that a simple area calculation would miss. Real bars still carry a rolling tolerance, so a weighed bar can differ by a small percentage.
- Can I get the weight in pounds?
- Yes. Every result is shown in both kilograms and pounds at the same time, and you can price the steel per kilogram or per pound. Length is entered in millimetres, centimetres or metres, since profiles are sold by the metre.
- Can I price the steel as well?
- Yes. Enter a price per kilogram (or per pound) and a currency, and the calculator multiplies it by the total weight. Leave it blank to see weight only.
- What if I have a custom or cut size that is not a standard section?
- Use the metal weight calculator instead. It works from raw dimensions for sheet, bar, tube, pipe and angle in any material, so it handles non-standard and cut-to-size parts that have no catalogue mass per metre.
