    Abstract. Arched steel thin-walled cold-bent profiles with trapezoidal corrugations are lightweight, economical, easy for installation. They are obtained by longitudinal rolling of a flat profile through a mobile rolling-bending machine with a system of three cassettes of rollers, at that the middle cassette having a vertical displacement relative to the extremes. To obtain the residual radius of the arched profile, the operator must specify the value of this displacement, at that he does not have data on the dependence of the values of the obtained residual radius of the profile and the specified parameter (vertical displacement of the average cassette of rollers) at the rolling-bending machine. As a result, it is necessary to perform several trial defective rollings. In the article the dependence of the value of the residual radius of the longitudinal rolling of the arched thin-walled profile on the specified parameter of the rolling-bending machine is determined experimentally and analytically. For ease of use, the results are presented in the form of continuous power equations and in tabular form for one of arch profiles with different thicknesses the most commonly used in the construction. The materials developed by the authors of the article will make it possible to produce arched profiles of a given radius with minimal losses of steel products.
    Key words: arched thin-walled cold-bent profile, trapezoidal corrugations, residual radius of longitudinal rolling, mobile rolling-bending machine ZEMAN.
