A curved surface structure for reflecting solar light, heat or electromagnetic radiation is made by scoring two opposing pairs of curved bend lines along one pair of opposing edges of a sheet of bendable material, dividing it into a center section joined by curved bend lines to curved ribs, joined by curved bend lines to respective curved edges; bending the curved ribs down and curved edges up along the bend lines to nominally right angles to form a curved surface supported by two curved ribs and two curved edges. Two straight ribs and respective straight edges may be scored and formed on the other pair of opposing edges of the sheet. A backside sheet may be applied to the four edges. A widthwise corrugated, elongate right angle reinforcement member may be employed for strengthening the formed bend lines.
