FIELD: metallic constructions. SUBSTANCE: rolled H-beam includes web and two flanges; each flange is joined with web through trough-like member whose convexity is directed to enter of cross section of shape. Thickness of trough-like member consists 0.8 - 1 of web thickness; material content of web consists 34.3%, material content of two trough-like members consists 27%; material content of web overhangs consists 38.7%. EFFECT: lowered material consumption of shape having improved characteristics such as moment of inertia and resisting moment. 2 dwg, 2 tbl, 1 ex _
