Score and form solar reflector

A method for forming a structure with a curved surface comprising:

• scoring a sheet of material with opposing pairs of parallel curved bend lines along one pair of opposing edges of the sheet, thereby dividing the sheet by two inner and two outer curved bend lines into sections comprising a center section joined by the inner curved bend lines to curved ribs, the curved ribs being joined by the outer curved bend lines to respective curved edges;
• bending the curved ribs along the inner curved bend lines to nominally right angles relative to the center section whereby the center section becomes a curved surface, and bending the curved edges along the outer curved bend lines to nominally right angles relative to the curved ribs.

A method for reinforcing a curved line of intersection between two surfaces comprising installing an elongate reinforcing member along the curved line of intersection, the reinforcing member comprising corrugated metallic material wherein corrugations run widthwise across the member, and further configured with a lengthwise bend angle sized to match an angle of the intersection between the two surfaces.

A pre-engineered reflector kit comprising:

• a sheet of material scored with opposing pairs of parallel curved bend lines along one pair of opposing edges of the sheet, thereby dividing the sheet by two inner and two outer curved bend lines into sections comprising a center section joined by the inner curved bend lines to curved ribs, the curved ribs being joined by the outer curved bend lines to respective curved edges;
• the inner curved bend lines being scored on a first side of the sheet and the outer curved bend lines being scored on a second side of the sheet.

A structure with a curved surface comprising:

• a sheet of material with a pair of curved bend lines formed along opposite edges of the sheet so as to divide the sheet into sections comprising a curved surface joined by the formed said bend lines to two respective curved ribs, the curvature of said bend lines and said ribs defining the curvature of the surface.
