Pick a standard profile from the table — IPE, IPN, HEA/HEB/HEM, UPN, UPE, angles, T sections, square, rectangular and round hollow sections, over a thousand sizes in all — or enter your own dimensions. The calculator shows the weight per metre, the total weight and the surface area to be painted. Useful for planning an order, estimating transport and working out paint consumption.

How we calculate
Standarta profiliem rādām EN standartu tabulu nominālās vērtības: svaru uz metru (G) un ārējās virsmas laukumu uz metru (AL). Tie ir tie paši skaitļi, kas ražotāju katalogos, tāpēc šis režīms ir precīzāks par aprēķinu no ģeometrijas. Citam materiālam tabulas svaru pārrēķinām pēc blīvuma attiecības pret tēraudu (7850 kg/m³). T profiliem tabulās nav virsmas laukuma, tāpēc to nerādām.
For custom dimensions the weight = cross-sectional area × length × density. We use 7850 kg/m³ for steel, 7900 for stainless, 2700 for aluminium and 8500 for brass. For hollow sections and angles the cross-section is calculated from the nominal dimensions without corner radii, so the result is 1–3 % higher than in manufacturers’ tables.
The actual weight of rolled sections can differ by up to ±5 % because of tolerances — the weight of an order is always confirmed against the actual batch.
