Bright steel wire is produced by cold forming wire rod. The wire is strengthened by drawing, resulting in a smooth surface, tight dimensional tolerances and high strength. The number of drawing devices depends on the inlet and outlet diameter, the wire quality and the desired reduction. Schlatter’s multiple drawing machines enable efficient processing of wires with small to medium diameters and low to medium carbon content. These wires are typically used for industrial applications such as nails, galvanized wire or wire ties. Depending on the requirements, the wire can either be wound onto spools or vertical wall studs after drawing.
Ribbed steel wire is used for the production of reinforcement elements with improved bond behavior in concrete, for example for reinforcing steel mesh, reinforcement cages or stirrups. The wire is profiled by cold forming. A ribbed wire is formed from bare steel wire using cold rolling cassettes. Longitudinal and transverse profiles are introduced to ensure optimum mechanical anchoring in the concrete. Schlatter’s cold rolling lines are characterized by their modular design and a wide range of configuration options. They are suitable for the production of spools and coils as well as for the automatic production of straightened bars. The degree of automation of the lines can be flexibly adapted to the specific requirements of each customer.
Stretched steel wire is a cold-formed wire that is stretched along its length using a special stretching process in order to improve its mechanical properties in a targeted manner. In particular, the tensile strength and yield strength are increased. This makes this wire ideal for applications with high strength and durability requirements – for example in reinforced concrete construction. Schlatter’s stretching and rewinding lines are primarily used to produce stretched and/or rewound compact coils of classes 500 B or 500 C that meet all current European and international standards. If the line is upgraded accordingly, class 500 A reinforcement material for cold rolling processes can also be produced on the same line.
