The strength properties and good weldability of structural hollow sections, steel profiles and steel piles make them light and long-lasting. These products are mostly used in construction and many engineering applications. Applications for the use of precision tubes can be found in the automotive industry, furniture, cycles and numerous other products within the light engineering sector. Precision tubes combine high strength, corrosion resistance, excellent machinability and good surface quality. Welded steel line pipes are suitable for the transmission of materials, heat and energy at both low and high operating temperatures.From a production point-of-view, these products follow a similar production route. The amount of scrap steel used varies between around 20–30 % of the steel charge depending on the steel grade and method of manufacture. In 2012, the average value was 20%. Use of energy and raw materials has been optimised in steel production.
