March 2026 --- # The frame system – the heart of our stage technology Posted on 17. April 202519. March 2026 ## 30 years of the HOAC® aluminium frame system – the heart of modern stage technology The HOAC® frame system – an indispensable tool for modern stage technology. But how did it actually come about? The answer is a brilliant man named** Martin Högg**, Managing Director of HOAC®. Together with the Aalto Theater in Essen, he developed the frame in 1993 **to solve a problem **that many theaters had been struggling with for a long time. Previously, in-house solutions made of wood or steel were used for screwing together, which were not only heavy and impractical, but also put a lot of strain on the material and quickly rendered it unusable.  With the development of the HOAC® aluminium frame system, the aim was to create a tool for the **quick and efficient assembly and disassembly** of stage equipment for theaters, making their daily work in the theater easier and more pleasant. In this blog article, we want to take a closer look at the frame and its versatile use in modern theaters. ## Table of contents [The most important facts in brief[The HOAC® aluminium frame system – continuously developed[The HOAC® link block – the heart of the frame[The HOAC® modular system – ingeniously simple](https://www.hoac.com/the-frame-system-the-heart-of-our-stage-technology/?output_format=md#the-hoac-modular-system-ingeniously-simple) ## The most important facts in brief * The HOAC® frame for connecting platform components is being continuously developed and offers enormous flexibility and efficiency when assembling and dismantling [platform elements](https://www.hoac.com/stage/stage-elements/?output_format=md). * At the heart of the frames is the HOAC® link block. This enables the various frame systems to be flexibly connected to each other. * With the help of the unique HOAC® modular system, consisting of frames and link blocks, HOAC® finds optimal solutions for the assembly and dismantling of any theater or orchestra stage. ## The HOAC® aluminium frame system – continuously developed HOAC® develops versatile frames for stages, turntables, grandstands, stage wagons and orchestra stages. Thanks to the **innovative system**, the frames can be flexibly exchanged and adapted to the individual needs of the customer. The frames are ** produced in Germany**. HOAC® attaches great importance to quality and precision. The HOAC® frame is one of the **most versatile and important components** for modern stage technology. Since its development, the frame system has constantly evolved and adapted to the needs of theaters. Today, there are a variety of different frames that are specially designed for the different requirements and needs of theater and orchestra stages. Another important development of the frame system is its **high efficiency and easy handling**. Modern HOAC® frames are designed to be quick and easy to assemble and disassemble, which saves time and resources and greatly improves workflow. They are also lighter and take up less space than previous models, making them easier to store and transport. The continuous development of the aluminium frame system helps to ensure that theater performances can now take place at a higher level than ever before. The frame provides an **indispensable foundation** for the entire stage technology and therefore contributes significantly to the success of a theater performance. ## The HOAC® link block – the heart of the aluminium frame system Just as the HOAC® frame is the heart of modern stage technology, the HOAC® link block is the heart of the frame. It makes it possible to connect the frames to each other effortlessly and without the use of tools. Thanks to this **simple and intuitive handling**, the permanently welded frames can be connected to each other in a mobile manner, which makes the assembly and dismantling of stage equipment, turntables etc. much easier and faster.  The special feature of the HOAC® system is the **compatibility of the different frame profiles **with each other, which is made possible by the innovative link block. This means that you can easily combine and connect any HOAC® profile with other profiles, which not only enables more flexible application options, but also supports the sustainability of the systems. This allows you to expand or adapt the HOAC® system in the long term and as required, without having to purchase completely new frames each time. ## The HOAC® modular system – ingeniously simple The HOAC® system not only offers standard aluminium frames system in various installation heights, but also other frame profiles that are **optimized for different applications**. For example, Flip2Play, the new folding practical aluminum cable, enables quick and easy stage construction. The TackIt system, on the other hand, is specially tailored to stage construction and other applications. Have you been convinced by the unique HOAC® aluminium frame system? Then we look forward to hearing from you – we will find the ideal solution for every theater stage! ## Post navigation [Stage wagon: You have these options](https://www.hoac.com/stage-wagon-you-have-these-options/) [The revolving stage and its applications](https://www.hoac.com/the-revolving-stage-and-its-applications/)
