Delfingen Industry SA

What Delfingen Industry SA does

Delfingen Industry SA is a France-headquartered, publicly listed (Euronext Paris: ALDEL) Tier 1 automotive supplier specializing in protection and routing solutions for vehicle electrical networks and fluid-carrying systems. Founded in 1954 in Anteuil by Emile Streit as a small family plastic-bag producer, it has grown into a global manufacturer operating 41 industrial sites and 10 R&D centers across 21 countries with 4,200+ employees, serving essentially every major global OEM (BMW, Mercedes-Benz, Ford, GM, Honda, Toyota, Volkswagen Group, Stellantis, Renault-Nissan-Mitsubishi, JLR, Volvo, Porsche, Ferrari, Maserati, Alfa Romeo, Subaru) and Tier 1s (Lear, Delphi).

The product portfolio is organized around four solution areas: Protection Systems (cable-harness protection including convoluted, smooth, braided and flat tubing, plus heat-resistant Nu-Sleeve and shielding Nu-Shield families), Fluid Transfer Tubing (fuel-tank, under-hood and washer systems built on extrusion, forming and plastic processing), Interior Trim Fastening (seat profiles, bi-material and felt products), and Assembly & Logistics Services (last-mile JIT, line-side delivery, multi-component sub-assembly). Underlying technology is essentially industrial materials processing (extrusion, braiding, plastic/textile forming) across multiple polymer families (PET, PA, PPS, PVC, TPV, silicone), differentiated by application-specific certifications for temperature, fire retardance, EMI shielding and noise reduction. Branded sub-families — Langoflex, Polyflex, Nu-Guard, Nu-Kool, Nu-Flex, Nu-Sleeve, Nu-Shield — cover a wide specification envelope. Delfingen is family-controlled: Gérald Streit has been CEO since 2015 and Chairman since January 2018, succeeding his father Bernard Streit.

Revenue is generated through long-term B2B supply contracts negotiated directly with automotive OEMs and Tier 1 equipment manufacturers, with quote-based pricing that is not publicly disclosed. The model is anchored on a 'local-supply-globally' footprint that supports OEM platform strategies across regions (US/Mexico, Brazil, Europe, China, India, ASEAN, Morocco, Tunisia, UAE). The company supplements organic growth with M&A — HILEC (2012), Kartar Wire (2013), Langendorf/MBG and Tianhai Hengbang (2014), Drossbach N.A. (2016), REIKU GmbH and AHN Chem (2023) — and most recently a joint venture with Indonesia's PT Askara Internal (January 2026). ESG positioning has been formalized through an EthiFinance silver medal (2024) and the French RFAR responsible-purchasing label (February 2025).

Broad incumbents

• Furukawa Electric: Japanese manufacturer of automotive wiring harnesses, electrical components, and protection materials. Comparable in automotive wire-protection materials and as a Tier 1 harness supplier to Japanese OEMs.
• Aptiv PLC: Global Tier 1 automotive technology supplier (formerly Delphi). Overlaps with Delfingen in electrical architecture and connection systems, though Aptiv operates at much greater scale and broader portfolio.
• TE Connectivity: Global manufacturer of connectivity and sensor solutions including automotive wire protection, tubing, and cable management. Overlaps with Delfingen's protection-systems portfolio though TE serves many end markets beyond automotive.

Direct peers

• Coroplast Group: Germany-based manufacturer of adhesive tapes, cables, and wire-harness protection products (woven and non-woven sleeving). Closely comparable in Delfingen's core Nu-Sleeve and Langoflex product families.
• Kromberg & Schubert: German Tier 1 wiring harness manufacturer serving premium European OEMs (Audi, Porsche, BMW, Mercedes). Comparable customer base and wiring-system product overlap with Delfingen.
