Cold Drawing Facility

In our combined cold drawing facilities, cold drawing production is carried out from coils up to 40.00 mm in section size and from bars up to 150.00 mm. Our cold drawing facilities have an annual production capacity of 100,000 tons.

Production Lines in Our Cold Drawing Facilities:

• 8 Schumag brand combined drawing machines for coil-based production
• 15 chain-type cold drawing benches for flat, square, and round products
• 15 shot blasting machines for flat, square, and round products

Cold-Drawn Steel Production Process

1. Raw Material Selection and Preparation

For the cold drawing process, hot-rolled bars or coils are first selected. These materials undergo surface cleaning to remove oxide layers through:

  • Shot blasting

  • Mechanical cleaning

This step reduces surface defects and ensures homogeneous deformation during the drawing process.

2. Cold Drawing Process

The cleaned material is drawn through dies at room temperature. During this stage, the steel's cross-section is reduced, its length increases, and surface quality is improved.

Key properties gained through cold drawing:

  • Dimensional precision

  • Increased mechanical strength

  • Improved surface quality

  • Enhanced cross-sectional geometry

3. Straightening

Minor bends that may occur during drawing are corrected using specialized straightening machines. This step is especially critical for industries requiring tight dimensional accuracy.

4. Cutting and Sizing

Drawn bars are cut into the required lengths. This stage is carried out according to requests such as:

  • Full-length products

  • Custom fixed lengths

  • Specific packaging standards

5. Heat Treatment (Optional)

For certain applications, heat treatment is applied to balance the toughness or hardness of the steel:

  • Annealing

  • Normalizing

  • Induction hardening (for specific steel grades)

Heat treatment ensures that the product maintains high strength while being optimized for machinability.

Technical Characteristics of Cold-Drawn Steels

  • High surface quality

  • Tight tolerances and precise dimensions

  • High mechanical strength

  • Harder and more durable structure

  • Improved machining performance

  • Reduced internal stress (with heat treatment)

Compared to hot-rolled products, cold-drawn steels have a much smoother surface and a more homogeneous structure.

Areas of Use

Cold-drawn steels are preferred across many industries that require precision:

  • Automotive components

  • Machinery manufacturing

  • Shafts, pins, and axles

  • Furniture and fastener production

  • Hydraulic–pneumatic equipment

  • Textile machines

  • Screen, frame, and profile applications

  • Bolt, nut, and screw manufacturing

Thanks to their durability, dimensional accuracy, and high performance, cold-drawn steels play a critical role in engineering applications.
