Transportable Stage Elements by HOAC®
At HOAC®, we offer mobile seating systems, rotating stages, and folding stage rows for any requirement. Whether you need stage rails, stairs, decks, or other modular bleachers, we provide expert solutions based on decades of experience in theater platforms and stage construction.
Our telescopic, folding tribunes offer maximum flexibility and high reliability. No matter how often or how far you need to transport your bleachers, our portable, modular construction enables fast and easy setup and teardown, saving steps and effort.
This product line is complemented by lightweight panels, rolling tables, and additional platform solutions. As a certified welding company, we comply with strict safety standards and deliver retractable, high-quality stage structures.
Custom Manufacturing
Whether 2 meters or 1.73 meters – we manufacture in any row or module size. Learn more in our technical details.
Force & Form Fit
Our chairs and bleachers are designed for dynamic loads, thanks to their force- and form-fit connections.
Safe & Certified
As a specialist welding company, we manufacture all products in accordance with DIN EN 1090 1–3 and ISO 3834–2. You can fully trust the quality and safety of our tribune and telescopic platforms.
Fast & Modular
Assembly and disassembly of the grandstands is quick and tool-free – essential in theater and event operations.
Flexible Lightweight Construction – What Makes Our Stage Elements Unique
Our stage platforms are made of aluminum – significantly lighter than steel – and ideal for mobile, indoor use. Telescopic structures made of steel are often heavier and harder to maneuver. That’s why our aluminum systems support safer and faster installation, reducing strain on staff.
We’ll help you choose the ideal grandstand for your audience needs, whether it’s stability or adjustable height that matters most. Optional height-adjustable beams are available, always maintaining safety on stage – even for lighter or retracted elements.
Applications of Our Mobile Stage Platforms
In auditoriums for both classic and experimental performances.
For theater productions on tour.
For orchestra stages, ramps, and uneven floors.
Setup Made Easy
Deadlines are tight – productions need to switch quickly between shows. That’s why ease of use is critical. Our telescopic platforms, folding chairs, and bleachers can be assembled fast and without tools.
Thanks to the lightweight structure and innovative mounting, the setup becomes child’s play. Our systems deliver quality, speed, and safety in every detail.
