Product Specifications

Prepainted steel consists of a steel core, a metallic coating, a primer and a top coat. Built on hot-dip galvanized, ZAM or Aluzinc substrates, it combines corrosion protection, formability and decorative surface performance.

Commercial and special grades are available according to EN, ASTM and JIS norms.
