EN1090 Factory Production Control

The EN1090 certification is the foundation in fabrication of load bearing steel and aluminum structures like retractable grandstands.

Engineering & Production

All the engineering, research & development and production of our retractable grandstands and mobile telescopic stands takes place in our offices and production halls in Oudenaarde.

From the initial idea to the engineering, possibly prototyping for new developments, to the final production and assembly of the parts: all steps are supervised by the project manager assigned to the project and the production manager.

Installation, completion & after sales

Preparations for transport, delivery, assembly, aesthetic finishing, calibration, delivery and comprehensive training are carried out by our own team of skilled and certified professionals.

For maintenance and support to any brand of retractable stand, you can rely on our maintenance and service team as part of an annual maintenance and service contract. Of course, we are also ready for interventions in urgent situations.

Insights from our experts and news from the industry

A retractable grandstand (also known as a telescopic stand) is a type of stand used in multi-purpose sports, cultural and educational buildings to make a hall multifunctional for different users and applications. The structure is designed to take up minimal space when fully retracted. When extended, visitors can be seated with a good view of the stage or playing field.
