FIELD: construction.
SUBSTANCE: invention is related to construction, in particular to metal column. Column of double-tee section comprises two parallel stands and wall. Wall along length represents a combination of transversely or longitudinally corrugated sections and smooth sections. Length of transversely corrugated and smooth sections does not exceed doubled width of wall. Wall along length may represent a combination of transversely or longitudinally corrugated sections and transversely corrugated sections with corrugations having lower height and higher pitch. Connection of sections is carried out directly with the help of welded joint or via installation of transverse diaphragms.
EFFECT: reduction of material intensity.
