A sparse-isogrid columnar lattice structure including rigid ring frames connected by a mirrored symmetric double helix pattern comprised of first shell hinge elements in a first helical pattern and second shell hinge elements in a second helical pattern oriented in an opposite direction to the first helical pattern and congruent thereto. The helical axes of the first and second helical patterns intersect the respective centers of the ring frames. The first and second shell hinge elements are configured to stow in a stored energy state when the ring frames are collapsed toward one another along the helical axis, and the first and second shell hinge elements are configured to release the stored energy to deploy to a restored state and extend the ring frames apart from each other along the helical axis when deployed to form a stable rigid axial column in a restored state.
