Precision in steel since 1904
The PRÄZI GROUP, led by PRÄZI-FLACHSTAHL AG, pools the expertise of five medium-sized manufacturing companies at five locations in Germany, Italy, the Czech Republic and Hungary. The group manufactures precision flat steel to DIN 59350, drawing-compliant finished parts such as sliding guides, guide rails and custom machine parts, industrial and machine knives up to 5,000 mm in one-piece length, forming tools and wear parts for sand-lime brick and concrete block production, as well as rotationally symmetrical components, assembly groups, screw conveyors and solid feed-in systems for biogas plants. The in-house value chain includes sawing, CNC machining, segment and circumference grinding in a climate-controlled room, heat treatment with salt bath, tempering and induction hardening up to 5,400 mm workpiece length, as well as surface treatment and assembly. The material basis comprises precision tool steels such as 1.2379, 1.2363, 1.2842, 1.2343 (ESU), 1.2083, 1.4112, 1.7225 and TOOLOX® grades. Customers include mechanical and plant engineering, tool and die making, the sand-lime brick and concrete block industry, the biogas and biomass industry, agricultural and conveying technology, and the plastics, food, recycling, paper and wood industries. Founded in 1904 and 100 % owned by the family of Günther Claas, the family-run company employs over 500 staff and supplies more than 15,500 customers worldwide.
