Gpi Tanks XL constructs stainless steel tanks. We take care of the whole process from start to finish, beginning with design by our own engineers, followed by production, transport and installation. At our XL production location, we construct tanks with capacities of max. 5000 m3 and on site with diameters and heights up to 30 metres. Our location in Groot-Ammers is located adjacent to the river, so we can ship tanks directly using the waterways.
