About Chaland-Palmieri
Chaland-Palmieri is a contract manufacturer specialising in tube processing, based in Barby (Savoie, France), with more than 60 years of experience. The company produces bent tube assemblies, tube modules, serpentine coils and mechanically welded assemblies from study and prototype through to small and medium series. The process chain includes cold bending with large and small radii (including on an 11-axis CNC bending machine), tube laser cutting, roll bending, end machining, thread cutting, high-frequency and conventional brazing/soldering as well as robot-assisted TIG, MIG and MAG welding, complemented by passivation, industrial painting, polishing and assembly. Materials processed include high-strength steel (HLE), structural steel, stainless steel, aluminium, copper and titanium. Customers come from the automotive, military technology, medical technology, general industry, oil/petroleum equipment, fluid transport and leisure sectors. An in-house design office supports customers with component optimisation. In 2024/2025 the production floor was extended by 150 m² and a new bending machine for diameters up to 120 mm was installed.

Materials & Processes
High-strength steel (acier HLE)
For cold-bent tubes with high strength requirements, with small and large radii.
Structural steel
Standard material for tube bending, laser cutting and mechanically welded constructions.
Stainless steel
For serpentine coils, handles and components with polishing or passivation, e.g. in medical and fluid engineering.
Aluminium
Tube systems with small or large radii, including for lightweight applications.
Copper
For tubes and components in fluid transport, also joinable by brazing/soldering.
Titanium
For demanding tube applications with high corrosion and strength requirements.
