Prepainted Galvalume Steel Coil And Sheets 55% AL For Producing PPGL


1. Why we choose GL as substrate of color coated steel?


The PPGL is more and more popular within 5 years since its has more merits than GL:

Firstly, the corrosive resistance of the hot-dip alu-zinc coated steel sheet is twice to fifth times as mush as that of the hot-dip zinc- coated base metal.

Secondly, it can satisfy the processing requirements of rolling, coiling and others processes alike.

Thirdly, the color won't change while continuously or intermittently working with an ambient temperature up to 316℃.

Neither serious oxygenation nor oxide scale might appear while continuously or intermittently working with an ambient temperature up to 490℃.

Last but not least, the heat and the light reflected are respectively twice as much as those of hot-dip zinc steel sheet, and its reflectivity is more than 0.75, exceeding 0.65 (required by the EPA Energy Star Standard), which is an ideal construction material of saving energy.


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 thicknessThickness tolerance while the widths are showed as follows
Common precise PT.AHigh-level precision PT.A
≤1200>1200-1500>1500≤1200>1200-1500>1500

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:
