Tanks for processing and storage of high-quality productss

Gpi manufactures stainless steel storage tanks from 500 litres to 15,000 m³. Depending on the destination, we can build the tanks in our factory in Lopik, in our factory in Groot-Ammers, or construct them directly on-site. We produce high-grade tanks and storage tanks up to a diameter of 6 m at our Lopik facility. If the tank cannot be transported by road, we often create storage tanks at our location in Groot Ammers. This factory is located right on the banks of the river Lek, allowing us to transport the tanks via water. If transporting the tanks to you is not an option, we can also build tanks up to 30 meters in diameter and 30 meters in height directly on-site.
