Dans le secteur de la construction, il est utilis\u00e9 pour la cr\u00e9ation de charpentes, de ponts et de structures industrielles, garantissant durabilit\u00e9 et capacit\u00e9 de charge. En fabrication m\u00e9canique, il est transform\u00e9 en composants cl\u00e9s tels que des arbres, des engrenages et des bases de machines pour assurer la stabilit\u00e9 des \u00e9quipements. Dans les projets d&#039;infrastructure, il est utilis\u00e9 pour la construction de voies ferr\u00e9es, de pyl\u00f4nes \u00e9lectriques et de composants automobiles. De plus, dans des secteurs tels que la construction navale, les \u00e9quipements chimiques et les installations \u00e9nerg\u00e9tiques, l&#039;acier au carbone pour poutres en H est indispensable.

Il doit son nom \u00e0 sa section transversale en forme de \u00ab\u00a0H\u00a0\u00bb. Il pr\u00e9sente une r\u00e9sistance \u00e9lev\u00e9e, une bonne capacit\u00e9 portante et une excellente r\u00e9sistance \u00e0 la flexion. Il est souvent utilis\u00e9 dans des structures telles que les charpentes de b\u00e2timents, les ponts et les installations industrielles. Sa masse volumique est d&#039;environ 7,85\u00a0g\/cm\u00b3, son point de fusion est compris entre 1\u00a0370 et 1\u00a0510\u00a0\u00b0C et son faible coefficient de dilatation thermique le rend adapt\u00e9 aux environnements \u00e0 temp\u00e9ratures \u00e9lev\u00e9es et aux grands \u00e9carts de temp\u00e9rature. Un traitement de surface (galvanisation ou peinture, par exemple) permet d&#039;am\u00e9liorer sa r\u00e9sistance \u00e0 la corrosion et de prolonger sa dur\u00e9e de vie.
