What CSN Carl Schreiber does
CSN Carl Schreiber GmbH is a German specialty manufacturer founded in 1837 that produces custom-made copper molds (Kupferkokillen) for continuous steel casting. The company serves global industrial steel manufacturers with a product portfolio spanning thin slabs (Dünnbrammen), thick slabs (Dickbrammen) up to 4 meters wide, beam blanks, blooms exceeding 1 meter in diameter, and pipe molds (Rohrkokillen). All molds are manufactured from high-performance copper-silver (CuAg) and copper-chromium-zirconium (CuCrZr) alloys, with semi-finished materials sourced from sister company Elsässer Industries, providing vertical integration into alloy supply. Production is one-off custom manufacturing at the company's operational site in Wilnsdorf, Germany; the registered headquarters is in Gräfelfing (Amtsgericht München, HRB 241386). The firm is privately held as a GmbH.
The company's core technical differentiator is its patented horizontal installation of glass fiber temperature sensors, co-developed with Belgian partner EBDS and combined with the Emerald Breakout Detection System for real-time, high-resolution temperature monitoring during the casting process. This capability supports casting using the Emerald process and is positioned around steel quality consistency and process reliability for industrial steel producers operating beyond standard specifications.
CSN operates as a private GmbH, family-owned for over 180 years and led since 2018 by Managing Director (Geschäftsführer) Joseph Meseha and partners. The go-to-market model is enterprise field sales, with direct engagement to global industrial customers. Pricing is quote-based given custom specifications, no public pricing or revenue is disclosed, and products are shipped directly to customers worldwide. Brand presence is maintained through a corporate website (csnmetals.de) with German and English variants and a LinkedIn company page.
