Product Description

Product Description
Aluminium-zinc coating (AZ) 55%Zinc Coated
is applied by dipping steel into a bath of molten metal consisting of 55% aluminium and 1.6% silicon (with the remaining being taken up by zinc). The combined action of these metals ensures the best corrosion protection compared with other coatings.

Aluzinc& Galvalume Steel Coil
The galvalume & aluzinc steel sheet in coil uses the cold-rolled steel sheet as a substrate and solidified by 55% aluminum, 43.4% zinc and 1.6% silicon at 600 °C. It combines the physical protection and high durability of aluminum and the electrochemical protection of zinc. It is also called aluzinc steel coil.


  • Strong corrosion resistance, 3 times that of galvanized steel coil.
  • The density of 55% aluminum is smaller than the density of zinc. When the weight is the same and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3% or larger than that of the galvanized steel sheet.

Product Description

Aluzinc Galvalume Steel Coils VS. Galvanized Steel CoilBecause this Aluzinc layers coating has very good corrosion resistance ability which offers it 2-6 times the life span versus galvanized steel coils. Developed from hot dipped zinc galvanized and hot-dipped aluminum galvanization tech, galvalume steel combines with excellent characteristics of both products, premium corrosion and oxidation resistance of hot dipped aluminum galvanization and exceptional electrochemical properties of hot dipped zinc coated galvanization, which gives galvalume steel strong anti-rust and anti-corrosion ability at the edge and on the scratched surface.

Corrosion resistance

Galvanized coil is defined as a carbon steel sheet coated with zinc on both sides. Zinc coating is one of the most effective andeconomical methods to protect bare steel plates. Zinc can act as a barrier between steel and the environment, it will sacrificeitself to protect the steel plate below.

Good quality

The zinc layer has uniform thickness and strong adhesion. The zinc layer has uniform thickness and strong adhesion. It does not peel off during processing and has good corrosion resistance. It will not corrode for 20 years.The surface is very smooth and clean.The spangles are symmetrical and beautiful.55% Hot DippedGalvalume Steel in Coil (GL)

Dx51d 55% Hot Dipped Al Zn Galvalume Steel Coil Hot-Dipped Gl Coils

Galvalume is a coating consisting of zinc, aluminum and silicon that is used to protect a metal (primarily steel) from oxidation. It is similar to galvanizing in that it is a sacrificial metal coating which protects the base metal.

Corrosion Resistance & Self- Healing Properties

Galvalume's chemical formula was specifically designed to combine the toughness, strength, and self-healing properties of zinc with the rust resisting properties of aluminum. That's why Galvalume's corrosion resistance is about two to four times better than galvanized steel.Before Galvalume came into existence, most metal roofing was galvanized steel. However, because of the superior durability and corrosion resistance of Galvalume, the metal roofing industry transitioned from galvanized substrates to a Galvalume substrate is more and more popular.

Dx51d 55% Hot Dipped Al Zn Galvalume Steel Coil Hot-Dipped Gl Coils

Galvalume combines three of the most high-performing and important metals used in roofing today - steel, aluminum, and zinc. Manufacturers begin with a cold-rolled carbon steel base sheet that is continuously hot-dipped with aluminum and zinc alloys (AZ) until it reaches a coating of 55% aluminum, 43.4% zinc, and 1.6% silicone. LIYING Steel introduced the Galvalume coating to the construction industry in the early CHINA. This process allows for one material to have some of the best characteristics of each metal, which is why it's become one of the most popular metals used in metal roofing.
Substrate selection: AZ150 (150 g/m2 galvanized aluminum);
G345A high-strength galvanized aluminum steel sheet (55% aluminum, 43% zinc and 1.6% silicon)
Corrosion resistance data: 5% NaCl35 C, 1000 hours, good site The scribe is less than 2 mm.

Q.U.V: 2000 hours, the maximum color difference is 2, and the light retention rate is over 90%.

Ordinary color steel coil is a composite material, also known as color coated steel sheet, which is formed by continuous chemical transfer treatment of strip steel on the production line by surface degreasing, phosphating, organic coating and baking. It has both steel and organic materials. It not only has the mechanical strength and easy forming properties of the steel sheet, but also has good decorative and corrosion resistance.

As you can see, the difference between aluminized color steel plate and galvanized color steel plate and color steel coil is still very obvious. The color coated plate has the characteristics of corrosion resistance and weather resistance, and the color steel coil not only has the mechanical strength and easy forming property of the steel plate, but also has good decorative property and corrosion resistance of organic materials, and has corrosion resistance and corrosion resistance.

Color steel coil is a composite material, also known as color steel plate. The product is continuously chemically transferred to the strip on the production line, such as degreasing, phosphating, etc., and is coated with organic paint and dried.

Aluminum galvanized color coated board is a new material produced by domestic high-end applications in recent years, commonly known as CCLI. It is made of galvanized aluminum plated steel (55% aluminum, 43% zinc, 1.6% silicon). It has better corrosion resistance than galvanized steel. It is degreased, phosphatized, complexed and coated with organic paint.
