Sun Star on Signal Hill

Cape Town has a new beacon of light, shining brightly into the night…and the future. It’s the new 24-metre high art installation, designed by artist Christopher Swift, that is now providing a physical and figurative glimmer of light in Cape Town.The large-scale art installation takes the shape of a star tetrahedron, or a perfect cube. Installed on Signal Hill the structure has been designed by overlapping two tetrahedrons made from V400 Triangular Truss.

Purpose made corners were fabricated with interlocking laser cut 10mm 6082-T6 Aluminium plates welded to our standard V400 triangular truss profile. The massive star tetrahedron is 19.6m high. It has been placed on specially designed legs that follow the contour of the hill and result in an overall height of 22.6m. Viewing the star directly from above gives the star a 333.5 m2 footprint and spans 24m from point to point. With over 300 meters of truss the weight of just the star is 3200kg.

Wind loads and resonance were calculated for the structure at 300km/h
