A wide range of disciplines

The group acts in each sector with the highest reliability :

Engineering : a common R&D department for the  group.

Hydraulics : We realized hydraulic-sets, hydrostatic transmissions, lubrication systems and centralized lubrication.

Inflatable department : created a few years ago to increase services proposed to customers

Metallic construction sector: Euroconcept has been totally reorganized and 2 flame & plasma cutting centers have been settled. They are able to cut steel plates with important thickness range.

metalworks repairing or "metal surgery" : for 25 years, this original process which links 2 broken pieces by inserting bars has prouved its efficiency.

Precision manufacturing : about 12 manufacturing centers fitted with digital-driven,  a metrology room fitted with a three-dimensional equipment to control and more than 2000 measuring instruments linked with a calibration chain, BNM. This performing workshop can be useful in Public Works sector or Railway industry or Textile factories…

Railway : Europ’maintenance’s teams work all around France.  They assure maintenance and railway after-sales service :

  • Retrofit and filling of new coaches
  • Electrical repairing, wiring
  • Control, put in operation
Formwork and shoring : Buildings and public works. Val'eco group  offers "multi-products" solutions (renting or selling) : metallic formwork, metal shoring, lathes, safety material, …

Industrial maintenance : from preventive maintenance to recovery, all the industrial sectors are concerned. Interventions are planned on sites, plant sustainments, repairing , material modernizations (workshop or building site), after-sales service contract.

Industrial electricity and automatism : Compliance assessments, low tension wiring, golem programming.

Industrial tubing and plumbing : survey, pre manufacturing, assemblying and testing on site. Our speciality : incineration plants. Some 30 employees work in France and Belgium.

Mechanic : as the group owns a workshop specialized in general mechanic, it can react very quickly.

Metallurgical control and thermal treatment : Thermival has a laboratory fitted with very sophisticated means to realize destructive and non-destructive testings ( pulling machine, "mouton pendule Charpy", microscopes, macroscopes, mobil stéthoscope, control instrument ultrasonic sounds). It also realizes vertical thermal treatments until 1200°C ( standardization, quenching, "revenu", "hypertrempe", "recuit" and "détentionnement"…).

Logistics : HIOLLE Industries’ has developped a  multimodal platform (80 000 m²). it is used by supercenters but also can be used for any kind of logistics needs such as transfers.

Electronics : specialized in creation and realization of electronic systems for specific applications, Rhéa Electronique can realize CAD surveys and electronic tracks development. (all steps)

Complementary activities

Each subsidiary is self-governed. Meanwhile, all the subsidiaries work together and enjoy the totallity of Hiolle Industries’means. That’s what there is a true synergy inside the group.


For great projects, the holding federates the various competences. So, the group is able to present a global offer and marks its difference from its competitors.
