Abstract
A length composite member comprising a metallic sheet and a rigid synthetic resin coating is bent to be arcuate in transversal section. The thickness of the metallic sheet of such composite member as bent to be arcuate in transversal section is extremely small as compared with the radius of curvature of the desired arcuate sectional curve. A plurality of small arcuate sectional bent portions in transversal section are formed distributed in the transversal or width direction of the metallic sheet. The centers of the respective curvatures of these plurality of small arcuate, sectional bent portions in transversal section are selected to exist on the same side as that of the center of curvature of the composite member bent to be arcuate. The metallic sheet is generally bent in advance to be arcuate in transversal section and both main surfaces of the metallic sheet thus bent are coated with rigid synthetic resin. The thickness of the coated layers of the rigid synthetic resin is selected to be sufficiently large as compared with that of the metallic sheet.
