The use of rectangular steel tubes over the years has become widespread, above all to favor the construction of load-bearing structures. Today the pipe market is increasingly broad and varied: rectangular, square and circular, thanks to the improvement of technologies.
Steel profiles have big advantages, because they are lighter and cheaper and can be used both in industrial and civil environments.
Among the companies that produce rectangular tubes today there is Montastahl, which uses different technologies in compliance with the Uni En regulation. The processing methods include hot rolling and maintaining at high temperatures, or hot rolling, bending and cold welding.
