Aluzinc

If you need better rust protection than traditional hot-dip galvanized material, Aluzink can be a good option. By using an alloy of 55 % aluminum, 43.4 % zinc, and 1.6 % silicon, you get both a thinner and better rust protection. Aluzink is well the only type of sheet metal that has an attractive appearance, which has been noticed in many house builds in recent years. Aluzink is sold in thicknesses of 0.4-2.0 mm.
