Fiche produit<\/h2>\n<p>Le tube de type D haute r\u00e9sistance de nuance 700, \u00e9galement appel\u00e9 tube semi-circulaire en D, est un profil\u00e9 creux en acier form\u00e9 \u00e0 froid. Il est fabriqu\u00e9 \u00e0 partir d\u2019une bande d\u2019acier haute r\u00e9sistance de nuance 700 par cintrage \u00e0 froid et soudage \u00e0 haute fr\u00e9quence. Le profil en D pr\u00e9sente un c\u00f4t\u00e9 plat et un c\u00f4t\u00e9 incurv\u00e9 semi-circulaire. Par rapport aux tubes en acier au carbone ordinaires, l'acier de grade 700 offre une r\u00e9sistance sup\u00e9rieure pour un poids plus faible. Il est largement utilis\u00e9 dans les projets de remorques l\u00e9g\u00e8res et convient aux commandes destin\u00e9es \u00e0 l'exportation vers l'\u00e9tranger, exp\u00e9di\u00e9es par navire de fret g\u00e9n\u00e9ral.<\/p>\n<h2>2.
