The kg/m values in the EAS standard profile catalogue are calculated with 2.70. For sheet and plate the common 1050 alloy is 2.71.

Square tube weight calculation formula

Hollow section with a square profile.

kg = 4 × s × (a − s) × L × ρ ÷ 1 000 000

L = length · ρ = density (g/cm³)

For profiles the volume is cross-section area × length; for sheet and plate it is width × length × thickness. The cross-section areas here come from the same geometry engine that draws the catalogue sections, verified against the kg/m values of 1,949 catalogue profiles.

Example: a 3000 × 1500 × 1 mm plate → 3 × 1.5 × 1 × 2.71 = 12.195 kg. For 234 pieces, 2,854 kg.

Results are theoretical; production tolerance, surface treatment (anodising/coating) and cutting allowance are not included.
