Dans le secteur de la construction, ils sont utilis\u00e9s pour les charpentes, les \u00e9chafaudages et les pipelines. Dans le secteur p\u00e9trolier et gazier, ils servent de conduites de transport pour les fluides non corrosifs. En g\u00e9nie m\u00e9canique, ils servent \u00e0 la fabrication de composants tels que des arbres, des engrenages et des supports. De plus, ils sont couramment utilis\u00e9s dans les syst\u00e8mes d&#039;approvisionnement en eau, les syst\u00e8mes de chauffage et les r\u00e9seaux de tuyauterie industrielle.
