HEA 180 weight per metre and per length
An HEA 180 weighs 35.5 kg per metre (23.9 lb/ft). A 6 m bar therefore weighs 213 kg and a 12 m bar 426 kg. The section is 171 mm deep and 180 mm wide. HEA is the light wide-flange series: its depth, here 171 mm, is less than the nominal size.

The next size down, HEA 160, weighs 5.1 kg/m less; the next size up, HEA 200, 6.8 kg/m more. Same nominal size, another series: IPE 180 180 × 91 mm, 18.8 kg/m · HEB 180 180 × 180 mm, 51.2 kg/m · UPN 180 180 × 70 mm, 22.0 kg/m.
Where the numbers come from
Mass per metre and dimensions are the nominal values of the European standard sections (EN 10365), from the table of every IPE, HEA, HEB and UPN size; the rolling tolerance on mass is ±4 %. Everything else on this page is worked out from it: mass per metre times length, differences and metres per tonne. Web and flange thickness, section area and moments of inertia are not here: for design, use the maker's section table.
