GPI

What GPI does

Gpi is a Dutch industrial manufacturer specializing in custom-built stainless steel storage and process tanks, serving the food & beverage, pharmaceutical, chemical, oil & energy, and cosmetics industries. Founded in 1994 and headquartered in Lopik, the Netherlands, the company operates a project-based engineering-to-installation model in which sales engineers translate customer specifications into bespoke tank designs, manufacture the units at dedicated facilities, and deliver them with on-site installation services. Tank capacities range from 500 litres to 10,000 m³ (with some product lines reaching 15,000 m³), and construction includes on-site assembly of oversized units up to 30 metres in diameter and height through the Gpi Tanks XL subsidiary.

The product portfolio spans API 650 and EN 14015 storage tanks, KIWA-certified chemical tanks, double-walled tanks with vacuum or level-sensor leak detection, pressure vessels, chemical reactors, dairy and beer tanks (BBT, CCT), CIP systems, multi-chamber tanks, silos, and scraped surface heat exchangers. Materials include stainless steel 304(L), 316(L), 904L, and duplex/super duplex grades. The company holds a dense certification stack — ASME U, PED Module H & H1, UKCA PER, EN 1090-1/EX3, ISO 9001/14001/45001, KIWA BRL-K756-03 and BRL-K21051-01, DIN EN ISO 3834-2, EHEDG, WHG, VCA**, and ATEX — that functions as a regulatory moat across its served verticals.

Commercially, Gpi generates revenue primarily through one-time project-based contracts with quote-based pricing determined by tank capacity, material grade, certification requirements, and project complexity, supplemented by installation and assembly professional services. Manufacturing is concentrated in the Netherlands (Lopik and Groot-Ammers, the latter sited on the river Lek for waterborne transport of oversized vessels) and Poland (Skarbimierz and Brzeg), with engineering and sales offices in Germany and India, and independent sales agents Alekto AS and Alekto Process AB covering Norway and Sweden. Customers include enterprise names such as Cargill Bioindustrial, Mavitec, Dechra Pharmaceuticals, FrieslandCampina, and logos visible on the corporate site including Bunge, McCain, Arla, and Innocent. The company is led by co-founders Fred Boere and Arno Rodenburg (Co-CEO/COO), with Fons Geurts listed as founder and owner.
