We’ve just finished a massive, custom-designed, truss circle (22 meter diameter!) for our long time Taiwanese client - Full Dome Pro (www.fulldome.pro). Full Dome Pro specialize in the fabrication of full dome projection systems for planetariums and other venues. For this project, the final client was the South Korean government, which ordered the “complete solution” from Full Dome Pro.
The custom circle, which serves to support the lights and projection equipment, was constructed with specially designed, rectangular MILOS truss measuring 950mm tall x 880 mm wide x 50 cm deep. Each truss section includes ladder bars that enable Full Dome Pro staff to climb within the circle on-site to install the projection system equipment.
