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 | |||||
