CORO carbide rolls de� ne a new standard in wire reduction. On top of the re� ned roll surface,

the CORO carbide rolls impress by their long roll working life.

Thanks to the application of the most modern methods in addition to the use of the best

materials available, our employees manufacture products which supply the highest possible

process reliability for the operation of cold rolling lines. You can make savings not only due

to lower machine downtimes, but also through reduced wear, less material failure and

wire scrap.

Pro� t by the double bene� ts of CORO carbide rolls:

decisive cost advantage through highest process reliability and roll working life

increased wire quality through improved surface � nishing and rib geometry

The range of services provided by CORO includes standard and individual customer solutions.

Our specialists will take a very close look at your speci� c requirements and develop solutions

tailored to your individual needs.

CORO will provide service support throughout the entire operating life of your rolls.

CORO carbide rollsThe right solution to every requirement

Oval reducing, round reducing, sizing, forming and pro� ling rolls for the production of smooth

and ribbed wire.

CORO carbide rolls are used especially in situations where productivity and wire quality are

the most important factors. Examples include the production of reinforcing mesh for the

construction industry or the production of � nished wire for the manufacture of fences and

other industrial meshes.

CORO roll holders Your biggest plus for process reliability

As a manufacturer, we recommend the use of CORO roll holders for the highest process

reliability of your cold rolling lines and the longest possible working life of your rolls.

The holders are made from carbonised and hardened housings and run exclusively on

SKF bearings.

The special Viton O-rings and the optimum grease of the bearings ensure enormously high

temperature resistance and very low grease consumption.
