Aluzinc Steel Coil

The composition of Aluzinc steel coil is composed of 55% aluminum, 43.4% zinc, and 1.6% silicon by weight. The product is formed by a continuous hot-dip galvanizing process. The corrosion resistance is increased under the action of zinc and aluminum. 6 times higher than galvanized steel coil. It is also called Zincalume or Galvalume, Zincalume is a brand of the Australian company Bluescope. Galvalume is a trademark of BIEC International Inc.

FAQ

Is Aluzinc better than galvanized?

The composition of galvanized steel is 99% zinc, which sacrifices zinc to prevent rust. The ingredients of Aluzinc steel are aluminum, zinc, and silicon. Aluminum protects zinc and zinc protects steel, which can last longer than galvanized steel. Aluzinc steel coil has better heat resistance and corrosion resistance, about 2-4 times higher than galvanized.

What is the lifespan of Aluzinc?

The service life of Aluzinc is related to the use environment and the weight of the metal coating. Under normal atmospheric conditions, the life of AZ150-weight Aluzinc steel is about 15 years, and in a marine environment, the life is almost 10 years.
