Seamless rolled rings
We produce seamless rolled rings, flanges and wheel tires to the highest standards. This has made us one of the world’s leading manufacturers of ring blanks for a wide range of industries.
Ring blanks are produced from our raw ingot or raw billet material on piercing and upsetting presses, which are rolled out to diameters of up to 4,000 mm using our radial-axial rolling mills. The ring blanks are then finished using heat treatment and mechanical processing to meet the customer’s exact requirements.
