About Klingenstahl

Building Trust Through Precision Engineering

For over six decades, we've been the industry's most trusted name in electric steel cable manufacturing, innovation, and reliability.

Our Story

Founded in 1962 in Düsseldorf, Germany, Klingenstahl began as a small wire drawing workshop with a vision: to produce the world's finest electric steel cables. What started with 12 employees has grown into a global powerhouse employing over 4,500 people.

Our founder, Heinrich Klingen, pioneered several cable manufacturing techniques that remain industry standards today. His commitment to quality and innovation remains the cornerstone of everything we do.

Today, as a 100% employee-owned company, every team member shares in our success and has a personal stake in delivering excellence. This ownership culture drives the quality, innovation, and customer service that sets us apart.
