COS nv

About us - CREATORS OF S P A C E
COS nv is a privately-owned Belgian company specializing in the sustainable design, engineering, production, and installation of retractable grandstands and mobile retractable grandstands for sports, cultural, educational, and corporate venues.

All COS grandstands are developed in close collaboration with architects, clients, and end users, and fully comply with European Standard EN 13200, national regulations, and EN1090-certified Factory Production Control.

Our markets
COS is firmly rooted in Western Europe, with a strong presence in Belgium, the Netherlands, and France. Through strategic partnerships, our projects extend across Scandinavia, Southern and Eastern Europe, and selected regions in Africa. In addition, we realize exclusive projects in the Middle East together with our dedicated regional partner. This makes COS a trusted European reference in retractable grandstands with an expanding international footprint.

Rigid chain drive technology
Every electrical propulsed COS retractable grandstand is powered by our rigid chain technology. Unlike friction wheel motors, which depend on floor traction, our system pushes and pulls platforms independently from the floor. This ensures maximum reliability, safety, and longevity.

Beyond opening and closing, the system introduces advanced automation: chairs are folded and deployed automatically with each movement.

Mobile retractable grandstands
For arenas and multipurpose halls where flexibility and fast reconfiguration are essential, COS offers mobile retractable grandstands that are easy to operate.

Our TI26/32 and TI42/50 series are standard "ready-to-order" models with predefined dimensions and finishes. For unique requirements, we also design and deliver custom-engineered mobile solutions, proven in a variety of successful international projects.

Partners
This FSB 2025 edition we are present together with our Swedish partner AB Ilmonte and Hungarian & Romanian partner Wemat Global.
