What CORTS® Engineering does

CORTS® Engineering GmbH & Co. KG is a German family-owned engineering firm founded in 1835 and headquartered in Remscheid, Germany, specializing in flat bearings and engineering services for steel rolling mills. The company operates a focused portfolio of three core product lines plus supporting services: (1) CORTS® Mill Refurbishment, an on-site machining service using custom-designed mobile CNC-controlled milling equipment to return mill housings and chocks to OEM specifications; (2) CORC-g® Precision Wear Plates, a proprietary compound steel (hardened tool steel bearing surface bonded to a soft elastic base) functioning as precision flat bearings with superior wear and corrosion resistance; and (3) CADNO™ Roll Measurement, a mobile scanning-micrometer-based roll profile instrument for roll shops. Supporting offerings include optical 3D-metrology mill audits (up to 0.03mm precision), FEM analysis and gap optimization engineering services, the LUBtec greasing system (patent filed), and consulting. Trademarks are registered on CORTS®, CORC-g®, and CADNO™.

The business model is enterprise project-based: direct field sales deploys technical teams on-site at customer steel mills globally, delivering customized engineering solutions on a quote-by-quote basis with extended guarantee and warranty packages. The customer base is concentrated in tier-1 steel producers, with documented projects at Arcelor Mittal Temirtau (Kazakhstan), Arcelor Mittal Galati (Romania), Ternium Siderar (Argentina), and MMK Magnitogorsk (Russia), alongside a German home market. Marketing is primarily organic social and content (LinkedIn, Xing, Facebook, YouTube, Instagram, company website). The company is privately held under family ownership with no external investment; leadership is led by Klaus Jochen Corts as CEO.

Direct peers

• Fives: French industrial engineering group whose metals division (former Davy/Stein) designs and services rolling mills — directly comparable to CORTS in mill refurbishment and modernization project work.
• Danieli: Italian engineering company specializing in plants and equipment for the steel industry, including rolling mills and associated service/maintenance offerings directly comparable to CORTS's refurbishment scope.
• TMEIC: Toshiba Mitsubishi-Electric Industrial Systems Corporation, supplying drives, automation, and rolling mill technology — competing with CORTS for engineering and modernization scopes at large steel mills globally.
• Primetals Technologies: Austria/Japan-headquartered rolling mill and metallurgical plant technology provider offering modernization, retrofit, and lifecycle services for steel mills — the closest large-scale competitor to CORTS in rolling mill refurbishment.
• SMS group: German family-owned metallurgical plant builder and service provider for the steel industry, with strong overlap in rolling mill engineering, refurbishment, and aftermarket services targeting the same Arcelor Mittal-type customer base.

Broad incumbents

• ANDRITZ: Austrian industrial group with a metals forming (formerly ANDRITZ Kaiser / Sundwig) division supplying rolling mill equipment, modernization, and service — a broader incumbent with comparable mill-service offerings.
• SKF: Swedish global leader in bearings and rotating equipment services with industrial service offerings that overlap with CORTS in rolling mill maintenance and condition monitoring, though at much greater scale and broader portfolio.
• Schaeffler: German automotive and industrial supplier with a large industrial bearings and service business, including offerings for rolling mill applications — a broad incumbent with adjacent technology but a different specialization than CORTS's flat bearings.

Emerging players

• Hexagon Manufacturing Intelligence: Division of Hexagon AB providing CMMs, laser trackers, and optical comparators — overlapping with CORTS's metrology/inspection services (0.03mm precision) and rolling mill audit offerings in adjacent measurement categories.
• Renishaw: UK-based industrial metrology and precision measurement company whose probing, scanning, and gauging products overlap technically with CORTS's CADNO roll measurement and 3D-metrology audit instruments, though focused on broader industrial metrology use cases.
