description A method of producing, by universal mills, H-beams which are excellent in the strength and toughness of the joint between web and flanges. In roughing process, symmetric convexes, which have substantially the same cross section and differ in position in different mills, are alternately formed on at least either of the outer and inner sides of the web and flanges of the piece being rolled, to forcibly cause metal flow in the joints between web and flanges and thereby to increase the amount of strain of said joints. In finishing process, the convexes formed in said roughing process are pressed, thereby obtaining a H-beam having predetermined dimensions.
