Steel weight calculator. Any profile, in seconds.
Weigh tubes, round bar, flat bar, sheet and beams per piece, per metre and in total — for steel, stainless and aluminium. Free, no sign-up.
Result
- Per piece
- 5.33 kg
- Per metre
- 0.888 kg/m
Nominal weights from geometry and density. Beam weights per DIN 1025 / EN 10365.
Cross-section, times length, times density.
Every result is the profile’s cross-section times its length times the material’s density. Standard beams use their nominal mass per metre.
Tube
m = π × s × (D − s) × L × ρ
D outside diameter, s wall thickness, L length, ρ density
Round bar
m = π × (Ø ÷ 2)² × L × ρ
Ø diameter, L length, ρ density
Flat bar
m = b × s × L × ρ
b width, s thickness, L length, ρ density
Sheet
m = L × b × s × ρ
L length, b width, s thickness, ρ density
Beam
m = G × L
G nominal mass per metre (DIN 1025 / EN 10365), L length
Densities
- Steel (unalloyed)

Other materials scale by density: same geometry, different specific weight.
Steel weight, briefly answered
How do you calculate the weight of steel?
Cross-section times length times density. With dimensions in millimetres and density in kg/dm³: weight in kg = cross-section (mm²) × length (mm) × density ÷ 1,000,000.
What is the density of steel?
Unalloyed steel: 7.85 kg/dm³ (7,850 kg/m³). Stainless 1.4301 (V2A): 7.90 kg/dm³, stainless 1.4571 (V4A): 8.00 kg/dm³, aluminium: 2.70 kg/dm³.
How much does round bar Ø 20 mm weigh per metre?
2.47 kg per metre in unalloyed steel.
How much does a tube 33.7 × 2.6 mm weigh?
1.99 kg per metre in unalloyed steel, from π × s × (D − s) × ρ.
How much does 1 m² of 2 mm steel sheet weigh?
15.70 kg: sheet weight per square metre is the thickness in mm times the density in kg/dm³.
How much does an IPE 200 beam weigh?
22.40 kg per metre (nominal mass to DIN 1025-5), so a 6 m beam weighs 134.40 kg.
