GRILLO expertise in steel construction: Thermal-sprayed zinc coatings in focus

Whether industrial facilities, port infrastructure, or large transport structures – steel constructions today face demanding requirements. They must be durable, ensure reliable operational safety, and at the same time be operated more sustainably. Modern zinc and zinc-aluminium spray coatings offer compelling solutions and are internationally regarded as a robust alternative to conventional paint-based systems.

Against the backdrop of current discussions surrounding the durability of bridges, the need for high-performance corrosion protection systems is coming increasingly into focus. Particularly in the field of corrosion protection for steel bridges, it becomes clear how critical robust and low-maintenance coatings are for the long-term performance of such structures.

Dr.-Ing. Frank Prenger, Technical Director of GRILLO Zinc Metals GmbH, summarizes in his article the technical, economic, and ecological advantages of thermal-sprayed zinc coatings and outlines how their international use is evolving. He highlights key findings from research and practice, compares international approaches, and explains why the process—despite its potential—has so far been used only to a limited extent in Germany.
