What Jenssen does
Jenssen GmbH & Co. KG is a family-owned, owner-managed German stainless steel trading and processing company headquartered in Siegen, Germany (Eisenhüttenstraße 11-17, 57074). Founded in 1960, the company has operated continuously for over 60 years and specializes in stainless steel flat products — slit strips, sheets, and custom pre-cut parts — manufactured to DIN EN ISO 9445 tolerances and supported by value-added surface treatment (grinding, brushing, polishing per EN 10088-2), edge finishing, protective foil application, and contract processing services (slitting, cut-to-length, circling/stamping) for material thicknesses from 0.10 mm to 8.00 mm and widths up to 2000 mm.
The company carries a broad inventory across ferritic, martensitic, ferritic-austenitic (duplex), austenitic, and heat-resistant stainless steel grades, supplemented by a 'green stainless steel' offering produced with reduced CO2 emissions on customer request. Supply is qualified to multiple European and international standards (EN 10088, EN 10095, EN 10151, EN 10162, DIN EN ISO 9444/9445) and the company is DIN EN ISO 9001:2015 certified.
Jenssen generates revenue through two streams: transactional sales of stainless steel flat products from stock (with pricing tied to publicly disclosed alloy surcharges layered over negotiated base prices) and contract processing services for customers with internal capacity bottlenecks. GTM is direct B2B field sales supported by a personal steel-service advisory team, with a corporate website (German and English) serving as the primary digital channel for catalogs, surcharge PDFs, and contact. The primary customer segments are stainless steel processors and dealers plus industrial manufacturers requiring just-in-time supply of standard and special grades.
