Providing Innovative Fastening and Assembly Solutions for Ground-Mount Structures and Towers

Henrob's principal activity is designing and manufacturing self-piercing rivets (HSPR) and installation systems. Self-pierce riveting is a process of joining two or more layers using an engineered rivet. Unlike conventional riveting, HSPR does not require a drilled or punched hole.

Henrob has seen a growing demand for its innovative assembly solutions within the solar industry. Henrob's technology is well established in the automotive, transportation, and industrial markets, and is now catching on quickly within the solar industry. Mounting structures for utility-scale projects have proved to be a great fit for Henrob's technology because it offers the ability to increase the efficiency and throughput of the assembly process. For any pre-assembled mounting structure, the benefits of using Henrob's technology are significant.


HSPR joins a range of dissimilar materials such as steel, aluminum, plastics, composites and pre-coated or pre-painted materials. Benefits include low energy demands, fast cycle times, no heat, fumes, sparks or waste, repeatable quality and automatic rivet feed for continuous production.

Whether developing a new product or streamlining assembly of an existing one, you can rely on Henrob's experience and innovation in riveting technology. From standard tools to customized systems, from rivet joint design assistance to automated assembly cells, Henrob can find your optimal solution.
