Factory Price G550 AL ZN 55% AFP SGLCC Aluzinc Coated AZ150 Galvalume Steel Coils For Sale

Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance.

    Product Description

    Galvalume steel is also called Aluminum-Zinc Alloy Coated Steel, Zincalume steel, aluminized zinc steel (aluzinc steel), SGLC, The galvalume metal is composed of 55% aluminium, 43.4% zinc and 1.6% silicon solidified at 600 ~C. Its whole structure consists of aluminium-iron-silicon-zinc, forming a compact quaternary crystal alloy. The surface of the galvalume steel sheet is characterized by smooth, flat and gorgeous stars, and its base color is silver white. The special coating structure makes it have excellent corrosion resistance. The normal service life of galvalume steel sheet is up to 25a, and its heat resistance is good. It can be used in high temperature environment at 315 C. The adhesion between coating and paint film is good, and it has good processing performance. It can be punched, sheared and welded. The surface conductivity is very good.

    Resist rust, fire and elemental onslaughts with galvalume steel sheet and coil from Zegang Steel.

    Galvalume steel is carbon steel coated with an aluminum-zinc alloy using a continuous hot-dip process, combining the corrosion protection and high-temperature resistance of aluminum with the formability and galvanic protection of zinc.

    Product Advantages

    1.Corrosion resistance: When zinc is abraded, aluminum forms a dense layer of alumina that prevents further corrosion of the corrosive material inside.

    2.Heat resistance: Aluminum zinc alloy steel has good heat resistance and can withstand high temperatures of more than 300 degrees Celsius.

    3.Thermal reflexes: The heat reflectivity of Al Zn steel plate is very high, which is two times that of galvanized steel sheet.

    4.Economical efficiency: Since the density of 55% AL-Zn is smaller than the density of Zn, the aluminum-zinc-plated steel sheet is more than 3% larger than the area of the plated steel sheet when the weight is the same and the thickness of the gold-plated layer is the sam.
