HOAC® system frame
The Original

The Hoac® profiles are the heart of our stage technology. They are used in many ways for stages, grandstands, stage design, turntables, stage wagons and orchestra stages. Our aluminium frames are easy to assemble and very resilient. The system concept is in the foreground, which means that the frame profiles and accessories are compatible with each other. In this way, a stage can be transformed into a grandstand tomorrow, with little material and time expenditure. With our HOAC® modular frame system, we make it happen.
