The profile has two sole plates (17, 18) arranged perpendicular to ends of a core (10) i.e. ribbed/undulated longitudinal element. The core includes a longitudinal structural element with projections (12) and recesses (13), which respectively define contact surfaces in same plan parallel to a longitudinal axis (11) of the structural element. Each sole plate comprises an open hollow section with a U-shaped portion (19). The core includes lateral edges integrated to the hollow section such that a base of the U-shaped portion is arranged out of the profile. An independent claim is also included for a trestle comprising a profile. |
