Technical description: Structural hollow sections, steel profiles and steel piles are made from hot- rolled steel strip by cold forming and welding at SSAB’s sites in Hämeenlinna, Lappohja, Toijala, Oulainen and Pulkkila (Finland), or by cold forming, welding and hot stretch reducing at the Virsbo site (Sweden). The hot-rolled steel is manufactured at SSAB’s steel mill in Raahe (Finland). Choice of production site is determined according to, for example, product requirements and construction site location. Depending on their application, precision tubes can be manufactured from galvanized, cold-rolled or hot-rolled pickled steel.Steel plates, tubes or sections are first cut by flame cutting or sawing to the required length and then welded together, shot blasted and coated with paint. Surface treatment causes volatile organic compounds (VOC) emissions of approximately 5 kg per tonne produced. VOC emissions per tonne depend, however, on the weight of the structure and the chosen painting system.
