0.23x1219mm 9016 color coated steel coil ppgi used for sandwich panel
What is PPGI coil?
PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc,
typically with a hot dip zinc coated steel substrate. The term is an extension of GI which is a traditional a
bbreviation for Galvanized Iron.
What is difference between PPGL and PPGI?
Galvanized steel, PPGI, is coated completely with zinc, while Galvalume steel, PPGL, is coated with aluminum,
zinc, and a small amount of silicone. This provides superior corrosion resistance and durability over the typical
galvanized coating.
Applications for Pre-paint Steel Products
Prepainted steel is used in many applications including :
♦ Metal Roofing
♦ Garage Doors
♦ Lighting Fixtures
♦ Heating and Air-Conditioning

Color coated steel sheet development trend:
1, the use of higher quality substrates, the substrate surface, shape and dimensional accuracy
requirements are increasing.
2, improve the pretreatment process and pretreatment fluid, a small number of equipment, low
cost becomes the mainstream process, and continuously improve the stability of pretreatment
fluid, corrosion resistance, environmental protection performance.
3. Develop new coatings to improve color reproducibility, UV resistance, and corrosion resistance;
develop functional coatings that are resistant to contamination and heat absorption.
4, the unit equipment is more perfect.
5, cold embossing is cheaper than the hot embossing, beautiful appearance, strong three-dimensional sensation,
high strength, so cold embossing production technology has become a development trend.
