Fornax

What Fornax does

Fornax is a Turkish manufacturer of PVC and aluminum door and window hardware accessories, operating as a brand under Yelken Group from its headquarters and production facility in Esenyurt, Istanbul. The company's product portfolio is organized into four main categories: Door Systems (locked espagnolettes, mortise locks, cylinders, hinges, handles, corner welding wedges), Window Systems (single/double opening systems, aluminum double opening systems, double wing systems, window handles), Sliding Systems (simple, parallel, Hebeschiebe lift-and-slide, Pavo Slide, and folding sliding systems), and Other Products (double glazing accessories, transom accessories, mounting accessories, fly screen accessories, center link connection wedges, espagnolette counterparts, and facade trusses). Notable proprietary technology includes the YelkenCoat 480-hour corrosion resistance coating and folding sliding systems rated for 100 kg load capacity and 25,000 opening/closing cycles per DIN EN 13126-15.

The company's business model is anchored in B2B sales to window and door manufacturers, construction companies, and assembly operations, complemented by direct-to-customer transactions through an owned e-commerce platform (yelken.oduyo.com.tr) and international export distribution to numerous countries. Fornax operates under ISO 9001:2000 quality management certification (obtained 2007) and positions its product compatibility across multiple PVC window profile systems. Pricing is not publicly disclosed; enterprise transactions are quote-based while consumer purchases flow through the e-commerce cart. The company has no institutional investors, no external funding rounds, and no disclosed revenue figures.

Founded in 1969 by Mr. Süleyman Yelken, Fornax began as a sheet metal parts supplier before pivoting to PVC door and window accessories in the early 1990s. The company was formally incorporated as YELKEN MADENİ EŞYA SAN.TİC.LTD. in 1990, restructured as YELKEN KALIP A.Ş. in 2006, and operates today as YELKEN KALIP PENCERE KAPI AKS. ve METAL SAN. TİC. A.Ş. The historical Bosch Profilo supplier relationship during the 1980s enabled early scale before the strategic shift to the current fenestration hardware focus.
