The professional event technology landscape is set to converge in Buchholz, near Hamburg, on August 19, 2026, as Groh-P.A. Veranstaltungstechnik hosts an extensive Open Day dedicated to the future of modular exhibition construction. This industry event, centered on the globally recognized beMatrix system, aims to bridge the gap between traditional stand building and high-tech audiovisual integration. By opening its doors to entrepreneurs, exhibition builders, technical agencies, and marketing professionals, Groh-P.A. is positioning itself as a central hub for sustainable and technologically advanced presentation solutions in Northern Germany. The event, which is free of charge for registered attendees, will provide a comprehensive look at how modularity is redefining the economics and aesthetics of the modern trade fair.
The Evolution of Modular Exhibition Design: The beMatrix Standard
At the heart of the "beGROH" Open Day is the beMatrix modular system, a framework that has fundamentally altered the exhibition industry’s approach to temporary structures. Unlike traditional wood-based stand construction, which often results in significant waste following a three-day event, the beMatrix system utilizes high-grade, reusable aluminum frames. These frames are designed for longevity and versatility, allowing for a "Lego-like" assembly process that requires no specialized tools.
The technical superiority of the system lies in its 62mm matrix, which allows frames to be connected in any direction—up, down, left, or right. During the demonstration in Buchholz, Groh-P.A. will illustrate how these frames can be outfitted with various "skins," ranging from tensioned fabric graphics to hard panels. This flexibility ensures that while the underlying structure remains constant and sustainable, the outward appearance can be entirely customized to suit a brand’s specific identity. The shift toward such systems is driven by a dual need for cost-efficiency and environmental responsibility, as the reusable nature of aluminum frames significantly reduces the carbon footprint of event participation.
Integrated Audiovisual Innovation: The LEDskin Revolution
One of the primary highlights of the upcoming Open Day is the live demonstration of LEDskin, a product that has revolutionized how digital content is integrated into physical environments. Historically, incorporating LED walls into an exhibition stand required complex rigging or external support structures that often disrupted the visual continuity of the design. LEDskin solves this by being a part of the frame system itself.
The LED modules are designed to fit perfectly within the beMatrix frames, allowing for a seamless, flush finish where the screen becomes an indistinguishable part of the wall. At the Buchholz event, technical experts from Groh-P.A. will showcase how these screens can be positioned anywhere within a stand layout, creating dynamic focal points without the bulk of traditional mounting hardware. This integration allows for creative freedom, such as "breaking" the screen across corners or incorporating it into ceilings and floors, a level of versatility that is becoming increasingly demanded by high-end brands looking to create immersive experiences.
Smart Software and the Digital Workflow
Efficiency in the exhibition sector is not merely a matter of physical assembly but also of digital preparation. Groh-P.A. will introduce its proprietary software solutions designed to streamline the production process. A significant bottleneck in exhibition management is the verification of print data for large-scale fabric graphics. Incorrectly scaled files or low-resolution assets can lead to costly delays and material waste.
The software developed by Groh-P.A. automates the checking of print data, ensuring that every graphic fits the specified frame dimensions with mathematical precision before it ever reaches the printer. This digital-first approach minimizes human error and accelerates the transition from the design phase to the physical build. Visitors at the Open Day will have the opportunity to see this workflow in action, understanding how automated pre-flight checks contribute to the overall reliability of the service.
Practical Application: The leat con Case Study
To demonstrate the scalability and real-world efficacy of their systems, Groh-P.A. will present a detailed case study of the "leat con" (Live Entertainment and Technology Convention) held in Hamburg. For this major industry gathering, Groh-P.A. served as the primary technical partner, utilizing the beMatrix system to outfit the entire exhibition space.
This case study serves as a proof of concept for large-scale deployments. Rather than focusing on a single boutique stand, the leat con project required the coordination of dozens of interconnected areas, including keynote stages, networking lounges, and individual exhibitor booths. By analyzing the logistics of this event, Groh-P.A. will provide attendees with insights into the management of large inventories, the speed of deployment in high-pressure environments, and the aesthetic consistency that can be achieved across a massive floor plan.
Strategic Partnerships: Iraci and Mediahouse
The "beGROH" Open Day is structured as a collaborative ecosystem, featuring key partners who complete the value chain of event presentation. The printing specialist Iraci will be on-site to demonstrate the production of high-quality textile coverings. The process involves sophisticated sublimation printing techniques that ensure color accuracy and durability, which are critical for the high-intensity lighting environments found in modern exhibition halls.
Complementing the structural and visual elements, the Buchholz-based firm Mediahouse will present solutions for promotional materials and brand merchandise. This inclusion highlights the holistic nature of the event; a successful trade fair presence requires a synergy between the architectural environment (beMatrix), the digital messaging (LEDskin), and the physical brand touchpoints (merchandise). By bringing these partners together, Groh-P.A. offers a 360-degree view of the exhibition lifecycle.
The Business Model: Dry-Hire and Long-Term Solutions
Groh-P.A. is positioning itself not just as a service provider but as a strategic partner for other industry players. A significant portion of their operations is dedicated to the "dry-hire" market. This allows other exhibition builders and technical companies to rent the beMatrix components and LEDskin modules to execute their own projects without the massive capital expenditure required to own the inventory.
Furthermore, the company is expanding into the realm of long-term rentals and permanent installations. This is particularly relevant for corporate showrooms, retail environments, and recurring event series where a permanent purchase might not be as economically viable as a flexible rental agreement. Jan Grohmann-Falke, owner of Groh-P.A., emphasizes that the Open Day is intended as a platform for networking rather than a traditional sales pitch. The goal is to foster a community where industry professionals can experiment with the hardware and discuss collaborative opportunities.
Industry Context: The Shift Toward Sustainability and Efficiency
The timing of this Open Day is significant. The global exhibition industry is currently undergoing a structural transformation. Rising labor costs and shorter setup windows at major venues like the Hamburg Messe have made "quick-build" systems like beMatrix a necessity rather than a luxury. The ability to assemble a professional-grade stand with a smaller crew in half the time of traditional methods provides a clear competitive advantage.
Moreover, sustainability mandates from corporate clients are becoming more stringent. Companies are increasingly required to report on the environmental impact of their marketing activities. The shift from "build-and-burn" (single-use wood stands) to circular systems like the one promoted by Groh-P.A. aligns with these ESG (Environmental, Social, and Governance) goals. Aluminum frames can be used for over a decade, and at the end of their lifecycle, they are 100% recyclable.
