long product of open cross sections that has a cross-sectional shape similar to heavy sections, but instead of being obtained directly by hot rolling, is made by welding together combinations of hot-rolled long products, hot-rolled flat products and cold-rolled flat products (see: long product, flat products, heavy section), avatud ristlõikega pikktoode, mille ristlõike kuju sarnaneb jämeprofiilmetalli omaga, kuid mida ei valmistata vahetult kuumvaltsimise teel, vaid kuumvaltsitud pikktoodete, kuumvaltsitud lametoodete ja külmvaltsitud lametoodete kombinatsioonide kokkukeevitamise teel (vt pikktoode, lametoode, jämeprofiilmetall)
