Isogrids : Products based on triangular trusses.

Grid structures whose stiffeners form equilateral triangles.

An Isogrid panel is a plate (or face sheet) with triangular integral stiffening ribs (often called stringers). The triangular pattern was found to be very efficient because it takes advantage of the fact that triangular trusses are very effecient structures. The term isogrid is used because the structure acts like an isotropic material. We make things based on that.
