We are fundamental in our manufacturing approach.

The Company/factory was initially designed to manufacture heavy-walled drilling instruments (Drill Collars, HWDPs and Kellies) for Oil&Gas industry. The Mill has a closed production cycle: from the very steel smelting to finished. We also sell worldwide the most popular oil&gas and other steel grades in (forged) bars and/or billets.
