Wholesale Aluzinc Galvalume Steel Coil Aluminium Zinc Coil Galvalume Steel Plate

Galvalume is comprised of a steel sheet dipped in a coating of 55% aluminum, 43.4% zinc, and 1.6% silicone. The unique coating gives the steel greater protection from the elements, which allows it to outlast traditional galvanized steel.

Overall, Galvalume is suitable as a roof, wall, trim, accent, and more in most building applications in some of the most extreme environments, including hurricane zones, locations with high rain or snowfall, high-temperature regions, and more.

    Product Performance

    The performance of aluminized zinc over hot Galvalume during production and processing is mainly reflected in the following aspects:

    1. Processing performance

    Aluminized zinc steel sheet is similar to hot-dip Galvalume in terms of processability, and can fully meet the requirements of rolling, stamping, bending and other forms of processing.

    2. Corrosion resistance

    The test is under the premise of hot-dip Galvalume steel and aluminized zinc steel with the same thickness, coating and surface treatment. Aluminized zinc has better corrosion resistance than hot-dip Galvalume, and its service life is 2-6 times that of ordinary Galvalume steel.

    3. Light reflection performance

    Aluminized zinc has twice the ability to reflect heat and light than Galvalume steel, and its reflectivity is greater than 0.70, which is better than 0.65 specified by the EPA Energy Star.

    4. Heat resistance

    Ordinary hot-dip Galvalume products usually do not exceed 230 degrees, and 250 degrees will change color, while aluminized zinc plate can be used for a long time under 315 degrees. 120 hours at 300 degrees, Baosteel's heat-resistant passivated aluminum-zinc coated steel sheet has a much lower color change than aluminum and aluminum-plated sheets.

    5. Mechanical properties

    The mechanical properties of aluminized zinc steel are mainly manifested in yield strength, tensile strength, and elongation. Ordinary DC51D grade 150g / sq. Galvalume steel sheet generally has a yield strength between 140-300mpa, a tensile strength between 200-330, and elongation between 13-25. The grade of DC51D + AZ aluminized zinc-plated aluminized zinc steel plate with a yield of 150 grams/square is between 230-400mpa, the tensile strength is between 230-550, and the extension rail is between 15-45.

    Product Introduction

    Aluminized zinc-plated steel sheet is a cold-rolled hardened steel sheet with various strengths and thickness specifications as the base material, which is obtained by hot-dip plating. Its coating composition is 55% aluminum, 43.5% zinc, 1.5% silicon and appropriate trace elements.
