The transaction represents a great opportunity for both companies to grow and develop.
The acquisition of A.D. Tubi Inossidabili has created a new industrial hub of reference in the international stainless steel market. CPC Inox is one of the most important private service centres for stainless steel in Europe, and A.D. Tubi Inossidabili is historically recognised as one of the most solid welded tube companies in the world. Together, the merger has achieved two solid and highly competitive industrial realities, thanks to the strong complementarity of the companies.
A.D. Tubi Inossidabili and CPC Inox supply different sectors of the market without overlapping. This means the mergers translates into a significant group advantage, as it allows the companies to be present in multiple industrial sectors, further strengthening their market presence.
