GL Galvalume Steel Coil 55% DX51D+AZ GB For Color Coated Steel Coils Substrate

1. Characteristics of Galvalume

Galvalume is the result of an ideal alloy of aluminum and zinc. It consists of aluminum(55%), zinc(43.4%), and silicone(1.6%).

Characteristics of Galvalume:

1) Corrosion resistence:

At verious enviromental conditions, GL shows better corrosion resistence than GI if the thickness is same, its service life is 2 to 6 times than ordinary galvanized steel. The corrosion resistence in the machining parts is much better than that of hot-dip galvanized due to micro cracks demormation parts of aluminum zinc plate is smaller than hot-dip galvanized.

2) Heat resistence:

GL plate can be used for a long time even if under 315℃.

3) Heat reflective

The reflection coefficient is double than that of hot-dip galvanized steel, which can reduce the inner tempeture in summer

2. Thickness tolerance for hot dip Al-Zn substrate

For steel sheet and steel strip with a specified munimum yield strength less than 260MPa, the thickness tolerance should be in conformity with the following stipulations:

Thickness tolerance for the range of 10m adjacent to steel strip welding seam is allowed to be 50% greater than the soecified figure.

For the sheet and steel strip with a specified minimum yield strength not less than 260MPa, but less than 360MPa, and the grades of DX51D+AZ and S550GD+AZ, the thickness tolerance should be in conformity with the following stipulations:

Thickness tolerance for the range of 10m adjacent to steel strip welding seam is allowed to be 50% greater than the soecified figure.
