Our story

Storage platforms, our speciality since 1989

Founded in 1989 by Thierry Deblaton, TDEM initially specialised in installing industrial equipment, mainly platforms.

Building on this experience, and seeing that the platforms on the market lacked technical performance and capacity, the company chose to innovate: producing industrial platforms and mezzanines made entirely from hot-rolled steel sections. This choice allowed it to offer new products and higher-performing technical solutions.

Innovation, responsiveness and efficiency: these values have made TDEM3 a recognised player in industrial platforms in France. Extensive advisory experience, many references and an in-house engineering office enable us to offer a technical solution suited to every need.

The heart of TDEM3

Every mezzanine is calculated, not estimated

Since 1989, our engineering office has supported your projects from feasibility study to modelling. Loads, spans and supports are calculated for your building, and every drawing is checked before manufacturing.

We use industry-standard software for the calculation and drafting of steel structures, which ensures the accuracy of our projects from concept to workshop.

CE EN 1090 certified

TDEM3 complies with the European standard EN 1090, which governs the execution of steel structures. This certification required training our staff: welder qualification, a welding coordinator and training for the head of the engineering office. Periodic audits are carried out by independent bodies to check that the standard is correctly applied.

At TDEM3, the same team follows your project from start to finish: the engineering office that calculates the structure, the workshop that manufactures it and the crews who install it on your site. A single point of contact, from the first survey to final handover.

  • An integrated team: engineering office, manufacturing workshop and installation crews
  • Workshop equipped with CNC machines: machining line, plasma cutting, punching machine
TDEM3 manufacturing workshop in Comines: steel stock, welding stations and overhead crane
