The remaining 25% of shares minus one share are still owned by the former management of Palini.
The acquisition was financed using company funds, and through borrowing. A share price at purchase was not announced.
The company said the acquisition would allow EvrazHolding to enter new international markets using Palini's advantages as a sheet metal producer, and to gain a reliable client base for selling steel slabs outside Russia.
Mining and metallurgy group EvrazHolding is one of the world's largest steel producers. It produces 100% of Russia's rails, 80% of beams and channels, about 40% of long products, and about 40% of rebar production. The company produced 13.7 million tons of steel in 2004.
The group comprises Nizhny Tagil, West-Siberian and Novokuznetsk Iron and Steel Plants, Vysokogorsky and Kachkanarsky Ore Mining and Processing Plants, Raspadskaya Mine, and the Yuzhkuzbassugol and Neryungriugol companies.
