Borrelly

What Borrelly does

Borrelly is a French family-owned precision manufacturer of mechanical spring washers and related spring elements, headquartered in Saint-Laurent-d'Agny near Lyon and tracing back to a 1933 mechanical workshop founded by Alexandre Borrelly. Now in its fourth generation of family leadership under President Dominique Borrelly, the company specializes in corrugated wave washers, Ondufil® wave springs (simultaneously rolled and corrugated flat wire), Belleville disc springs, the patented ROB® optimized Belleville disc spring, diaphragm washers, ribbon springs, spiral retaining rings (Borrelly 360), and thin shim washers in thicknesses from 0.01mm to 3mm across carbon steel, stainless steel, Inconel, Phynox, CuBe2, aluminum, brass, phosphor bronze, plastic film, and carbon/epoxy composite. Products are designed in-house using classical strength-of-materials theory and finite element analysis, with over 2,000 standard references and 1,500+ tools kept in stock and precision ranges deliverable within roughly one week.

The company serves 12+ regulated end-markets — principally aeronautics, aerospace/space, automotive, nuclear, defense, motorsports, and medical — with named programs including European Space Program launcher mechanical energy storage and ISS docking, Framatome nuclear primary circuits, aerospace flight instruments and fuel systems, automotive Tier-1 steering and powertrain applications, and medical implants and surgical robots. Operations are held to EN 9100 (aerospace, since 2004, zero-deviation follow-up audit in April 2024), ISO 9001, Safety Nuclear (renewed October 2023), DPRV/AS9117 (since 2019), and ISO 19443, with IATF 16949 currently in progress for mass-production automotive volumes.

Borrelly generates revenue through one-off sale of catalog SKUs from stock, precision/serial production runs, and bespoke engineering projects handled by the in-house Engineering & Design Department, with public catalog pricing (e.g., standard ribbon springs from roughly €5.17 to €39.30 per unit under tiered quantity discounts and no minimum order). Distribution combines direct sales from the French HQ (multilingual: French, English, Italian, German) with regional channel partners Afim srl in Milan (Italy) and Pri Tech Co. in Daegu (South Korea), plus an e-commerce storefront for standard references; lead generation rests on a multilingual website, recurring trade-show presence (notably 20+ Paris Air Show participations), and direct engineering consultation.
