Sheet metal parts and assemblies, made near Lyon.
Laser cutting, CNC bending, welding, powder coating and assembly on one site — from a single prototype to series. Part of the Aries Group.
A complete sheet metal chain since 1956
Guret is where the Aries Group started. For almost seventy years the Brignais plant has cut, bent, welded, painted and assembled thin and mid-thickness sheet metal for French and European machine builders.
Everything happens on one site: Trumpf lasers, LVD press brakes with automatic tool changing, welding stations, a powder coating line and an assembly hall. A part can go from flat sheet to a painted, assembled and packed sub-assembly without leaving the plant.
A local engineering team turns your drawings into production — feasibility, flat patterns, welding jigs, PPAP files — and stays your contact through the series. When volumes grow or parts get heavier, our plants in Slovakia take over with the same methods.

Frequently asked questions
- What thickness do you work?
- Thin and mid-thickness sheet: from about 0.5 mm up to the 20 mm range for laser cutting, depending on the material. Heavier plate goes to our sister plants in Slovakia.
- Do you make prototypes and small series?
- Yes. Guret makes single prototypes and small series as well as repeat series, on the same machines.
- Do you paint and assemble?
- Yes. We powder coat in-house in any RAL colour, press in fasteners and mount mechanical sub-assemblies before packing.
- Where is the plant?
- In Brignais, in the Rhône, about 15 km south-west of Lyon, with quick access to the A7 and A45 motorways.
