B: Embossed PPGI, support wringkle,diamond,orange peel etc embossed surface.
C: Pattern PPGI, common pattern, wood grain, stone texture, brick texture etc.
Quality Control
1) Mechanical Properties Testing
room-temperature and high-temperature mechanical tests, Brinell hardness, HRC hardness,
Vickers hardness, micro-hardness, expansion, flattening, cupping, bending, compression.
2) Metallurgical & Corrosion Analysis
macrostructure analysis, fracture detection, conductivity/resistance, density, grain size, hydrogen
embrittlement, residual stress, dezincification corrosion, salt spray, annealing.
3) Dimensional & Surface Measurement
thickness, width, length, zinc coating quantity,paint adhesion,surface roughness etc.
Mainly Applications
1 Building and Construction
It is widely used for roofing sheet, wall cladding, ceiling, door, and shutter because
of its durability and various colors.
2 Home Appliances
Commonly applied to refrigerator panel, washing machine shell, air conditioner shell.

Prepainted Steel Coil Advantages:
Strong corrosion resistance, 3 times that of galvanized steel sheet.
The density of 55% aluminum is smaller than the density of zinc. When the weight is the same
and the thickness of the plating layer is the same, the area of the galvalume steel sheet is 3%
or larger than that of the galvanized steel sheet.
Color coated steel sheet is made by chemical pretreatment, preliminary coating and fine coating,
the quality of the coating is more even, stable and ideal than single spraying or brushing on the
surface of formed metal.
