In2Structures | SPD36 Roof

SPD36 Roof

SPD36 is the flagship of In2Structures'€™ Dome Roof Structures, with a massive 32.7m internal width. The SPD36 can accommodate 3 ton loading per arch and additional load arches can be added at 3m intervals giving an additional 5 ton capacity on these arches.

  • The SPD36 Cantilever is an optional addition to the standard MDR36 structure to extend the roof coverage.
  • Clear skins are used to give the structure a view from within.
  • The skins have been offset from the main structure so that ample climbing space is available for rigging.
  • Skins are black on the inside, enabling the structure to host day events with complete black-out.
