DIEPA: Reliable quality, continuous innovation

Since 1873, we have embodied reliability and continuous innovation in high-quality wire ropes.

Diepa Drahtseilwerk – Quality Leader Since 1873

DIEPA Drahtseile has been developing and producing high-quality wire ropes since 1873 at its location in Neustadt b. Coburg, in the heart of Germany. Our product portfolio includes rotation resistant and non-rotation resistant ropes, which are valued worldwide in the construction, port, industrial, offshore, and mining sectors. We understand the specific requirements of these industries and offer customized solutions that meet the highest standards of durability, performance, and safety.

As a quality leader with the promise of “MADE IN GERMANY,” Diepa Drahtseilwerk is committed to its production site in Germany and delivers top-quality products for global markets.

Safety

Ropes are a safety relevant machine element. Failures can lead to personal injury and property damage! Therefore, DIEPA develops ropes that reliably perform their function throughout their entire service life.

Cost-effectiveness

Nothing is more expensive than using an unsuitable rope! By using a DIEPA rope, you reduce crane downtime and replacement costs, which despite the higher initial price, leads to a reduction in overall costs.

Availability

Only the available rope can be used! We will gladly consider how we can guarantee this for you.
