Patent ID: 7520643

Claim:
A method for assembling a grid with a plurality of longitudinal and transverse components, the method comprising: providing a first grid component blank; imposing a cut pattern on the first grid component blank, the cut pattern defining a plurality of longitudinal grid components and a plurality of transverse grid component receiving areas on the longitudinal grid components, thereby defining a first grid component framework; bending the plurality of longitudinal grid components to an approximately perpendicular relation to the first grid component blank; providing a second grid component blank; imposing a cut pattern on the second grid component blank, the cut pattern defining a plurality of transverse grid components, and thereby defining a second grid component framework; bending the plurality of transverse grid components to an approximately perpendicular relation to the second grid component blank; and inserting the second grid component framework into the first grid component framework such that the plurality of transverse grid components are inserted into the plurality of transverse grid component receiving areas.
