FIELD: construction.
SUBSTANCE: method to manufacture a steep support of regular height-alternating section consists in formation of a closed polyhedral cross section. The support by height is made of two sections, which are formed from produced parts of the square pipe that is slant-cut on each side. At the same time the beginning of the slant cut at one end of the pipe is arranged in the middle of each side, and on the other end the beginning of the cuts is arranged with division of each side into larger and smaller parts. Besides, smaller parts of each side are grouped at opposite faces of the square pipe.
EFFECT: reduced labour intensiveness and cost of steel support manufacturing.
