HOT-ROLLED COLUMN H-SECTION Russian patent published in 2011 - IPC B21B1/08 

FIELD: process engineering.

SUBSTANCE: hot-rolled column H-section comprises two parallel flanges interjointed by wall. Section equal stability and higher reliability are bought about by making it with equal stability along main axes X and Y. Note here that flange width exceeds 29 times flange thickness. Wall materials-output ratio makes 20% of that of the entire section, while wall section height is governed by 4^th-degree equation.

EFFECT: improved operating performances of column H-sections used in steel structures of buildings.
