This acquisition marks the start to international expansion, first into Singapore and Hong Kong, then to Japan, China, Thailand and Malaysia. In 1994, Permasteelisa acquired the Dutch company Scheldebouw B.V. and, in 2001, the German company Josef Gartner GmbH.
Its headquarters are in Vittorio Veneto, Province of Treviso. After the acquisition of the Australian company Permasteel Industries Pty Ltd in 1986, which manufactured the curtain wall of the Sydney Opera House, the company's name was changed to Permasteelisa.
