Heinrich Heidecker E.K.

What Heinrich Heidecker E.K. does

Heinrich Heidecker E.K. is a German manufacturer of Milanaise metal mesh, a fine, closely woven metal mesh produced without individual links from round wire in precious metals (gold, silver, platinum), stainless steel, and brass. Founded in 1921 in Pforzheim and now in its fourth generation of family ownership under proprietor Benjamin Heidecker, the company operates from a single manufacturing facility relocated in 2024 to Gutenbergstraße 6 in Königsbach-Stein, near Pforzheim — Germany's historic center of jewelry and watchmaking. The business is structured as a sole proprietorship (e.K.) registered at Amtsgericht Mannheim under HRA 500847, with 100% family ownership and no external investors.

The company operates three product lines from a unified Milanaise weaving competency: (1) Milanaise watch straps in 14/18 karat gold and stainless steel, offered as raw bands or finished with folding or butterfly clasps; (2) Milanaise tubular chains, ropes, and spirals in diameters from 0.6 mm to 14 mm for fine and fashion jewelry; and (3) technical spiral mesh conveyor and furnace belts with temperature resistance up to 1200°C, in custom dimensions for heat-treatment and materials-handling applications. Manufacturing is conducted in-house in Germany with high vertical integration, and the company serves customers across Europe.

Revenue is generated through direct B2B sales (quote-based, no public pricing) and OEM/white-label manufacturing for watch and jewelry brands. Demand generation is website-led, supported by Google Ads search and remarketing, Meta social advertising, a Brevo-powered newsletter, and SalesViewer B2B visitor identification. No e-commerce storefront is operated; sales are consultative, with customer-specific specifications (width, thickness, weave density, taper, finish, branding) forming the basis of every quote. The customer base spans watch manufacturers, jewelry brands, goldsmiths and jewelers, hardening shops, and micro-mechanics manufacturers, with no named end-customer logos disclosed in the available data.
