Since 1989, Industrias Electro Químicas S.A. (IEQSA) has been continuously supplying the European Market with Zinc-Copper-Titanium sheets and coils. Since the beginning, this product has been manufactured according to European specifications. Before the competent authorities of the European Union approved norm EN988 for this product, IEQSA`s Zinc-Copper-Titanium sheets and coils were produced as per the demanding standards of the corresponding German Industrial Norm DIN 17770. Today, IEQSA’s sales of this product compete with the best-known brands made in Europe. Our compliance with the European Norm EN988 has been well established, through permanent inspections and certifications issued by the internationally renowned European inspectors Bureau Veritas, and test institutes such as the MPA-NRW (Materialprüfungsamt Nordrhein-Westfalen) of Germany.
