Our manufacture range

Our manufacture range

We manufacture roll rings from tungsten carbide and compound TC and steel, composite roll with TC roll rings, pinch rolls and guide rollers for hot rolling and cold rolling mills that produce wire rod, bar, deformed bar, and tubes.

We deliver the roll rings and rolls with unfinished blanks, semi-finished roll rings with ground inner diameter and thickness or full finished to your drawing. Roll rings are in smooth, grooved or ribbed/deformed condition as your require.
