Zinc Aluminum-Magnesium Coated Steel in Coils which is also called AM coated steel is our mill newly developed with coating layers of 100-200g (+/-10g) which owns very strong corrosion-resistant ability.
It consists of zinc,about 11% aluminum,3% magnesium and trace amounts of silicon.
The corrosion object is formed on the galvanized surface as Film, taking the function to prevent corrosion of the steel sheet.
The results of the salt spray test show that 70 grams of magnesium-magnesium-aluminum-zinc SST corrosion area of 5% require 700 hours, 100 grams of galvanized on the market as long as 100 hours.
