Levelers: Perfection for every part.

Enhance your production efficiency: ARKU levelers ensure flat metal sheets and parts with reduced internal stresses – for parts as thin as 0.1 mm up to a max thickness of 60 mm! Your benefit: immediate processing instead of time-consuming reworking.

Reproducible flatness. Always.

Our precision levelers are extremely precise and deliver consistently excellent results. Enormous added value: they save time and minimize both scrap and time wasted on rework.

Check out this video and see for yourself how our customers use ARKU straigtheners in their day-to-day flattening operations to gain a competitive advantage.

Modern and powerful. Our machines.

ARKU provides a complete range of high performance levelers: from precision levelers for metal parts, sheets, and plates to high performance coil straighteners capable of processing AHSS materials.

Our EcoMaster® series of precision levelers ensures that even the smallest metal parts and sheets are perfectly flat. Thicker parts require our powerful FlatMaster®. In contrast, our PlateMaster® is the perfect machine for sheet metal parts and plates with a large surface area.

The FlatJack® enables you to rapidly and precisely measure and check the flatness of parts on the leveler itself with a precision in the tenth of a millimeter range.
