China New Product Sgcc Prepainted Steel Strip - Pre Painted Steel Coil/PPGI255 – Lueding

The prepainted steel sheet in coil is a product obtained by subjecting a hot-dipped galvanized steel sheet, an galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating), followed by baking and curing.
●The total thickness of the pre-panted galvanized steel coil is composed of the base steel – coating -primer – top paint – protective layer thickness.
●The top paint thickness is 7-25μm, and the back paint thickness is 5-10μm. The thinner the base steel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher.
●Usually the paint coating material is polyester (PE) and the color of the back paint is white grey. The color can be customized according to the RAL color card or customer samples.
Special patterns can be made, such as wood grain, flower print, camouflage, brick.
1) PPGI also known as prepainted galvanized steel coil and color coated steel coil, with a hot dip zinc coated steel sheet substrate.
2) PPGL also known as prepainted galvalume steel coil, with a galvalume steel sheet as a substrate.

1.Protective and decorative properties
Due to the oil paint on the surface of the gi steel plate, the life service and corrosion resistance functions are outstanding
compared with galvanized steel. Besides, the color of ppgi products are more flexible and various as per customers’ preference.

2.Good fire protection action
PPGI products are advantageous in the field of interior decoration and building industry. Even though under the high temperature
condition, the surface of the coating can still be kept glossy and the there is no color change on the surface.

3.Excellent processing capacity
After bending and stamping, high grade color coated sheet is no drop off situation. The quality of the coating is far more
homogeneous, stable and ideal than that on the surface of the painted metal.
