Depending on the end use, plain, ribbed or stretched steel wires are produced, all of which place high demands on process stability and plant technology.

Plain steel wire – drawing processes with high precision

Plain steel wire is manufactured from wire rod by cold drawing. During this process, the wire is pulled through drawing dies and plastically deformed, resulting in work hardening of the material. This produces smooth surfaces, tight dimensional tolerances and high strength values. The number of drawing stages depends on the entry and exit diameters, the wire grade and the required reduction.

Multi-wire drawing machines from Schlatter are designed for the efficient processing of wires with small to medium diameters and low to medium carbon content. Typical applications include nails, galvanised wire and wire ties. Depending on downstream processing or logistical requirements, the drawn wire can be wound onto spools or onto vertical carriers.

Ribbed steel wire – improved bond performance in concrete

Ribbed steel wire is primarily used for reinforcement applications where reliable bonding between steel and concrete is essential, such as welded wire meshes, reinforcement cages and stirrups. The ribbing is produced by cold forming, in which defined longitudinal and transverse profiles are rolled into the plain wire using cold rolling cassettes. These ribs ensure effective mechanical anchorage in the concrete.

Schlatter’s cold rolling lines feature a modular design and offer a wide range of configuration options. They are suitable both for the production of coils and spools and for the automated manufacture of straightened bars. The degree of automation can be flexibly adapted to the specific requirements of each production facility.

Stretched steel wire – increased strength through controlled stretching

Stretched steel wire is a cold-formed product that is elongated in a controlled stretching process to improve its mechanical properties. In particular, tensile strength and yield strength are significantly increased. As a result, this type of wire is ideally suited for applications in reinforced concrete construction with high demands on load-bearing capacity and durability.

Using Schlatter stretching and re-spooling lines, compact coils of classes 500 B and 500 C can be produced in compliance with current European and international standards. With appropriate equipment, the same line can also be used to manufacture class 500 A reinforcement material for subsequent cold rolling processes.

Conclusion

The production of cold-formed steel wires requires precisely coordinated processes and high-performance plant technologies. Modern drawing, cold rolling and stretching lines enable economical manufacturing with consistently high product quality and a high degree of flexibility. Schlatter’s plant solutions play a key role in meeting these requirements, supporting reliable and standards-compliant production for a wide range of industrial and construction applications.
