FIELD: testing engineering.
SUBSTANCE: method comprises bending the edge members by a given angle to provide a specified bend radius symmetrically with respect to the longitudinal axis of the steel strip. The members of the strip are bent to define a chute-like member whose wall height relates to the width of the shelves as 0.3-0.7.
EFFECT: enhanced reliability.
