Overhead Line Construction

Optimally matched to your requirements

Optimally matched to your requirements

Product range, picking, packaging, labeling, logistics

In overhead line construction, we are well versed for decades. We are the leading supplier of fasteners in Europe in this industry.

Our product range includes all fasteners required for overhead line construction. Here we rely on long-standing and reliable partnerships with German suppliers. This is complemented by custom drawing parts. 

Warehousing is matched to the needs and requirements of the industry at our two locations. Even short-term projects weighing several tons can be serviced from stock, if necessary from one day to the next.

Adapted to the processes and installation conditions, we deliver the fasteners picked by tower or shot and thus offer you the added value of a frictionless assignment of the fasteners to the corresponding shot / component.

According to your specifications, this assignment is further simplified by customer-specific packaging and highly detailed, weather-resistant labeling.


Based on our many years of experience and partnership with our suppliers, we offer you comprehensive technical support and, if desired, coordination between customer, end customer and construction team.
