  • HSS Bending of Hollow Structural Sections

    2021-3-30u2002·u20022.1 Pyramid Rolling or Cold Bending. Cold bending using 'pyramid rollers' is a common curving technique used to create HSS members with a constant radius. The method involves running the member through between three rollers, oriented in a pyramid shape as shown in Figure 1, varying the distance between the rolls with successive passes.
