Jansens & Dieperink

What Jansens & Dieperink does

Jansens & Dieperink, founded in 1945 and headquartered in Zaandam, Netherlands, designs, manufactures, and on-site assembles large-scale industrial structures in aluminium, stainless steel, carbon steel, and special alloys for global petrochemical, chemical, plastics, and adjacent process industries. Its core offering centers on five product lines — storage silos, process silos, vessels, columns, and tanks — produced via a proprietary panel design system that subdivides equipment into engineered panels prefabricated in a 13,500 m² Dutch facility and shipped in standard 40-ft sea containers for field erection. This patented on-site welding and assembly methodology removes conventional transport constraints on equipment diameter and height, with maximum individual silo capacity reaching 8,000 m³. The company cites an installed base of 8,763 units and projects executed in 64 countries.

The business operates a project-based, quote-driven model with no public list pricing. Revenue is generated via direct sales by an in-house team targeting engineering firms, EPC contractors, and end-user industrial plants; over 95% of revenue is derived from exports. Customers are large enterprise petrochemical and chemical producers (e.g., Shell, ExxonMobil/Sabic, Borouge, Borealis, Sabic, Celanese, Covestro, Orpic, Socar, Dangote, Nan Ya). The go-to-market combines direct enterprise field sales with event/trade-show presence in petrochemical, chemical, and energy industrial sectors. Certifications — ISO 9001:2015, EN 1090-2:2018 EXC 2, EN 1090-3:2019 EXC 2, and EN ISO 3834-3:2021 — qualify the firm to bid on demanding European and Middle Eastern EPC work.

Jansens & Dieperink employs approximately 120–135 professionals, including engineers, production staff, and certified on-site welders/assembly specialists, and has expanded its served industries beyond petrochemicals into Carbon Capture & Utilisation (CCUS), Renewable Energy, Recycling & Circular Economy, and Food & Beverage. Marquee projects include 92 silos and 95 blenders at Borouge's Al Ruwais PE/PP facility and 54 silos and 14 blenders at Shell's Monaca, Pennsylvania petrochemical facility. The company is privately held with no evidence of public listing, subsidiaries, or parent organization in the input data.
