The peeled bar is supplied in a polished and straightened condition. This allows for a smoother surface finish, closer tolerances and better straightness, plastic forming as well as further machining.
Peeled bar gives customers the opportunity to rationalize production and reduce production costs. The extraordinary cleanliness of the steel reduces the risk of unexpected tool failures and downtime, and the excellent straightness minimises the risk of shocks and vibrations that can occur at high cutting speeds.
The good surface finish of Ovako’s peeled bar can sometimes eliminate the need for further surface finishing. This saves material, machining and production time.
Peeled bar product properties

We made it! But we are still not satisfied
What a journey! It took years of hard work to make our steelmaking operations more sustainable. In 2022, we went carbon neutral in all operations. But we´re still not satisfied - our journey towards steel production without CO2 emissions continues.
