Our certifications
Cold drawing is a mechanical transformation process that allows steel or stainless steel bars to be produced with dimensional tolerances accurate to within a micron.
This process guarantees improved mechanical properties of the steel (elastic limit, hardness, straightness) and consistent quality, which is essential for the manufacture of precision parts in the mechanical engineering, aerospace, and energy sectors.

Cold drawing and rolling capacities
We offer a wide range of grades to meet the specific needs of each sector.
These include: low-carbon steels (S250Pb / S300Pb), carbon steels (C22 to C50), low-alloy steels (42CrMo4, 20NiCrMo2, 100Cr6) and stainless steels (304, 316Ti).
Following this process, we obtain solid products that are:
- Square, round or flat bars
- Small-dimension drawn coils
As a European steel supplier, Gardette Industries is committed to offering customized solutions that meet the most demanding industry standards.

- 100% final inspection: Before shipment, each part undergoes a complete inspection. Our procedures are aligned with ISO 9001 and ISO/TS 16949 standards, guaranteeing reliability, safety, and performance for our most demanding customers.
Cold drawing manufacturing steps
The cold drawing process at Gardette Industries follows a series of rigorously controlled technical steps.
It begins with pickling, which cleans the surface of the material to prepare the steel for deformation. This is followed by cold rolling, which modifies the cross-section of the raw metal to obtain a precise and uniform shape.
The semi-finished product is then heat treated in a coil or bar furnace. This step releases the internal stresses created during cold rolling, stabilizes the metal's structure, and improves its mechanical properties.
After that, shot blasting removes the last impurities and prepares the surface for final processing.
Finally, the material is pulled through a drawing die, straightened by rollers, and then sheared to the desired length, resulting in a cold-drawn steel bar with perfectly controlled geometry.
Applications concrètes de l’étirage à froid
Cold drawing is essential for producing reliable and precise parts in challenging sectors. It guarantees dimensional reliability for the automotive and aerospace industries, geometric consistency for industrial machinery, and the mechanical strength required in defense, petrochemical, nuclear, and environmental applications.
Above all, Gardette Industries is currently the only manufacturer of keys in the world to have mastered the entire cold drawing process, in full compliance with NF EN 10277 and DIN 6880 standards. This unique expertise guarantees keys of exceptional precision, produced according to the most stringent quality standards and recognized by the leading international industrial players.
Frequently asked questions about cold drawing
What is the difference between cold rolling and cold drawing?
Cold rolling deforms the metal to reduce its cross-section, while cold drawing involves pulling the material through a die to obtain a precise bar or profile, with strict dimensional tolerances and improved mechanical strength.
What types of steel can be cold drawn?
All cold-rolled steels and stainless steels can be drawn, including specific grades such as 25CD4S. The choice depends on the desired mechanical characteristics and end applications in the industry.
Why choose a cold-drawn steel supplier in France?
Working with a French supplier such as Gardette Industries guarantees traceability, controlled quality, responsiveness, and compliance with NF EN 10277 and DIN 6880 standards, with a fully internalized process for reliable, customized products.
