This article attempts to consider some of the features of the calculation and operation of light trusses from rolling corners. Is given brief information about the history of the use of trusses from single corners, their advantages and some disadvantages, as well as the prospects for the use of structures of this type in modern construction practice. Based on the analysis of the design documentation for a number of industrial facilities built over the past two decades in the Khabarovsk Territory, are analyzed the most common mistakes that designers make when developing roof structures using trusses from single rolling angles.

Keywords: farm from single rolling corners; corrosion resistance of elements; eccentricity of the acting effort; loading nodal moment; the value of the coefficient of working conditions; farm support node; additional forces in compressed rods
