Abstract

A method of making a composite fabrication member having a shape selected from the group consisting of C-shape, U-shape, or Z-shape by providing first and third planar members suitable to form bases of a composite fabrication member, providing a second planar member suitable to form a web of a composite fabrication member, uncoiling and passing through accumulators the planar members, aligning the planar members, attaching the first, second, and third planar members together at respective side portions by induction welding to form a composite intermediate product to form a composite fabrication member having a shape selected from the group consisting of C-shape, lipped C-shape, U-shape, lipped U-shape, Z-shape or lipped Z-shape.

Abstract

A method of making a composite tube-shaped fabrication member by providing in coils a first planar member suitable to form a flange of a tube-shaped fabrication member, two second planar members suitable to form web portions of a tube-shaped frame member, and two third planar members suitable to form a portion of a flange of the tube-shaped member, uncoiling the coils fo first, second, and third planar members and passing them through accumulators, aligning the first, second, and third planar members adjacent respective side portions and attaching side portions of each planar member to respective side portions of adjacent planar members to form a composite intermediate product, and cold-forming to form a composite fabrication member of a desired shape.
