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:

Nominal thickness Thickness tolerance while the widths are showed as follows
Common precise PT.A High-level precision PT.A
≤1200 >1200-1500 >1500 ≤1200 >1200-1500 >1500
0.22-0.40 ±0.04 ±0.05 ±0.06 ±0.030 ±0.035 ±0.040
>0.40-0.60 ±0.04 ±0.05 ±0.06 ±0.035 ±0.040 ±0.045
>0.50-0.80 ±0.05 ±0.06 ±0.07 ±0.040 ±0.045 ±0.050
>0.80-1.00 ±0.06 ±0.07 ±0.08 ±0.045 ±0.050 ±0.060
>1.00-1.20 ±0.07 ±0.08 ±0.09 ±0.050 ±0.060 ±0.070
>1.20-1.60 ±0.10 ±0.11 ±0.12 ±0.060 ±0.070 ±0.080
>1.60-2.00 ±0.12 ±0.13 ±0.14 ±0.070 ±0.080 ±0.090

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:

Nominal thickness Thickness tolerance while the widths are showed as follows
Common precise PT.A High-level precision PT.A
≤1200 >1200-1500 >1500 ≤1200 >1200-1500 >1500
0.22-0.40 ±0.05 ±0.06 ±0.07 ±0.035 ±0.040 ±0.045
>0.40-0.60 ±0.05 ±0.06 ±0.07 ±0.040 ±0.045 ±0.050
>0.50-0.80 ±0.06 ±0.07 ±0.08 ±0.045 ±0.050 ±0.060
>0.80-1.00 ±0.07 ±0.08 ±0.09 ±0.050 ±0.060 ±0.070
>1.00-1.20 ±0.08 ±0.09 ±0.11 ±0.060 ±0.070 ±0.080
>1.20-1.60 ±0.11 ±0.13 ±0.14 ±0.070 ±0.080 ±0.090
>1.60-2.00 ±0.14 ±0.15 ±0.16 ±0.080 ±0.090 ±0.110

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