Aluzinc

Aluzinc (also known as Galvalume) features a coating composed of approximately 55% aluminum, 43.4% zinc, and 1.6% silicon, applied through a continuous hot-dip process. This tri-component alloy delivers up to seven times better corrosion protection compared to standard galvanizing, combining the barrier protection of aluminum with the galvanic protection of zinc. The silicon component ensures proper adhesion between the coating and the steel substrate. Aluzinc is recognized globally as one of the most durable metallic coatings available.
