FIELD: construction.
SUBSTANCE: invention relates to construction and can be used as rod elements at development of bearing structures of buildings and structures of various purposes. Tubular (roll-welded) composite section profile using paired forming elements, one of which is a L-bar, connected with welds in the longitudinal direction along the shelves foils. Herewith the other forming element used in pair with the L-bar is a C-shaped roll-formed profile or a trough roll-formed profile with two equal-size walls adjoining the shelves of L-bar.
EFFECT: technical result is simplification of connections of composite components of tubular (roll-welded) profiles, more uniform distribution of structural material along the perimeters of their cross sections, as well as wider layout and unifying capabilities for bearing structures, reduced cost.
