From April 13 to 17, 2026, the BenderWire Group will be exhibiting at WIRE in Düsseldorf—the world’s leading trade fair for the wire and cable industry. All of the Group’s sister companies will be there.

We’re looking forward to Düsseldorf—and to meaningful conversations

Stamm Feindrahtwerk, Hagener Feinstahl, Sassenscheid, TriStar, and Siri Wire are coming together in Düsseldorf—as what we are: a group of companies that covers the entire value chain, from pre-production to the finest specialty wire, all under one roof. For our customers and partners, this means having a single point of contact where they can experience the full range of our capabilities and materials.

Wire you can touch

What is particularly important to us at this year’s WIRE: We don’t just want to showcase our products and solutions—we want to bring them to life.

That’s why we’re bringing a microscope to our booth. No marketing promises, no glossy brochures—just a live look at what we manufacture every day. Visitors can measure our materials right there on the spot and see for themselves what precision down to 11 micrometers means.

Because wire at this level is not some abstract concept—it is the invisible material behind products that save lives, generate energy, and drive innovation. We are convinced that you have to experience it to truly understand it.

Connections that matter

For us, WIRE is more than just a trade show. It’s the time of year when the industry comes together—and that’s exactly what we want to take advantage of.

We are very much looking forward to meeting our valued customers and partners in person. Conversations that usually take place via email or phone take on a whole new dimension at WIRE. That is what makes trade shows so special.

We’re just as open to anyone who hasn’t met us yet. If you’d like to discuss sustainable wire innovations with us—new materials, new applications, new ways of thinking in an industry undergoing change—you’re more than welcome to stop by our booth. A conversation often starts with a single question.
