Steel weight calculator and bill of materials
Add beams, plates, pipes and bars with length and quantity. The calculator gives the weight per metre and per item from EN 10365 and EN 10219 section tables, totals the list by type and grade, and exports it to CSV or PDF.

What it calculates
- European sections: IPE, HEA, HEB, UPN, equal and unequal angles
- Hollow sections (box, rectangular, round) per EN 10219 with corner radii
- Plates, flat bars, round and square bars
- Steel, stainless and aluminium densities, optional price per kg
Formulas
Pipe: A = π·(D − t)·t
Box: A = 2t(B + H − 2t) − (4 − π)(ro² − ri²)
ro = 2t (t ≤ 6), 2.5t (t ≤ 10), 3t ; ri = ro − t
Angle: A = t(a + b − t)
m [kg/m] = A [mm²] × ρ [g/cm³] / 1000
Worked example
A 114.3 × 4 mm steel pipe has A = π × 110.3 × 4 = 1386 mm², so it weighs 10.9 kg/m. A 10 mm plate of 1000 × 2000 mm weighs 157 kg.

Frequently asked questions
How do I calculate the weight of a steel plate?
Multiply length × width × thickness by the density: 7.85 g/cm³ (7850 kg/m³) for steel. 1 m² of 10 mm plate weighs 78.5 kg.
Where do the beam weights come from?
From the EN 10365 tables for IPE, HE and UPN sections and EN 10219 for cold-formed hollow sections.
Can I export the list?
Yes, as CSV for Excel or as a PDF with your company details.
