Coated Steel

Aluminum zinc coated color coated roll

  • Aluminum zinc coated color coated roll

Overview

Also known as galvalume or zincalume steel, aluminum zinc steel is a cold-rolled galvanized steel with a metal coating consisting of 55% aluminum, 43% zinc, and 1.6% silicon. The unique composition of aluminum zinc steel endows it with unique characteristics, combining the physical protection and high durability of aluminum with the electrochemical protection of zinc.


Product characteristics



  • Excellent long-term corrosion resistance makes the performance of aluminum zinc steel coils 2 to 6 times better than that of galvanized coatings




  • The density of aluminum is 55% lower than that of zinc. When the weight and thickness of the coating are the same, the area of the galvanized steel plate is greater than or equal to 3% of the galvanized steel plate.
