Drawn wire treatments and certifications: Trafilerie F.lli Rotta’s complete offering

Trafilerie Fratelli Rotta offers a wide range of drawn steel wires designed for various industrial sectors. The products are made from low, medium, and high carbon steels, compliant with the European classifications SL, SM, SH, DM, and DH, ensuring reliable performance in different applications.

Range of diameters and technical specifications

The drawn wires are available in diameters ranging from 0.8 mm to 16 mm, offering flexibility for multiple uses. These products are certified according to European standards, ensuring quality and compliance with industry requirements.

Thermal and surface treatments

To enhance mechanical properties and corrosion resistance, the company offers a series of treatments, including:

- patenting: increases wire strength and ductility through a specific heat treatment;
- annealing: restores wire ductility, reducing hardness to facilitate further processing;
- galvanizing: applies a zinc coating to protect the wire against corrosion;
- phosphating: creates a protective layer on the wire surface, improving lubrication and corrosion resistance;
- oil-lubricated wire drawing: a phosphate-free process that gives the wire a glossy finish by applying the lubricant directly onto the bare wire.

Commitment to quality, safety, and the environment

Trafilerie F.lli Rotta is currently undergoing a major overhaul of its management systems, with the goal of updating its ISO 9001, ISO 14001, and ISO 45001 certifications. This process reflects the company’s focus on process quality, workplace safety, and environmental sustainability, further strengthening its market reliability and compliance with international standards.

Industrial applications of drawn wire

The steel wires produced by Trafilerie Fratelli Rotta are used in a wide variety of industrial sectors, thanks to their quality and versatility. In the automotive industry, they are used to manufacture critical components that require high standards of strength and reliability. The furniture sector also benefits from their properties, particularly in the production of mattress springs. In agriculture, these wires are used in equipment and structures that must withstand harsh environmental and mechanical conditions. In the field of industrial springs, Rotta wires are valued for their ability to resist high mechanical stress, meeting the demands of complex applications. Finally, wires intended for cold forming are made with specific mechanical characteristics, making them ideal for plastic deformation processes without preheating, and contributing to production efficiency and processing precision.

Innovation and international collaboration

The company has expanded its product range through collaborations with international brands, introducing innovative products such as steel wool wire in 3–4 mm diameters. This wire, with low carbon content and high manganese levels, offers excellent machinability and chip-forming performance, making it ideal for specific cleaning and surface finishing applications.
