Double Coated Color Painted PPGI/PPGL Steel Coils For Roofing And
Wall Cladding
PPGI & PPGL (prepainted galvanized steel & prepainted galvalume
steel) also known as pre-coated steel or color coated steel coil,
It is a product made of hot-dip galvanized steel sheet, hot-dip
galvalume steel sheet, electro galvanized steel sheet, etc. After
surface pretreatment, one or several layers of organic coating are
applied on the surface, and then baked and solidified. The color
coated steel coil is light in weight, beautiful in appearance, and
has good anti-corrosion performance, and can be directly processed.
The color is generally divided into gray, sea blue, brick red, etc.
It is mainly used in advertising, construction, decoration, home
appliances, electrical appliances, Furniture industry and
transportation industry. The coatings used for color coated steel
coils are based on the environment in which the resin is selected,
such as polyester silicon modified polyester, polyvinyl chloride
plastisol, polyvinylidene chloride, and the like.
PPGI/PPGL Steel Coil Coating Type
- Polyester (PE): Good adhesion, rich colors, wide range in formability and outdoor
durability, medium chemical resistance, and low cost.
- Silicon modified polyester(SMP): Good abrasion resistance and heat resistance, as well as good
external durability and chalking resistance, gloss retention,
general flexibility, and medium cost.
- High Durability Polyester(HDP): Excellent color retention and anti-ultraviolet performance,
excellent outdoor durability and anti-pulverization, good paint
film adhesion, rich color, excellent cost performance.
- Polyvinylidene Fluoride(PVDF): Excellent color retention and UV resistance, excellent outdoor
durability and chalking resistance, excellent solvent resistance,
good moldability, stain resistance, limited color, and high cost.

PPGI/PPGL Steel Coil Ues :
Color coated steel coil is mainly divided into three parts:
construction, household appliances and transportation.
Building is generally used to build the roof, wall and door of
industrial and commercial buildings such as steel structure
workshop, airport, warehouse and freezer.
Household appliances are used in the production of refrigerators
and large air conditioning systems, freezers, toasters, furniture,
etc.
Transportation industry is mainly used for oil pan, automobile
interior parts, etc.
PPGI/PPGL Advantages:
-Good durability and long life compared with galvanized steel.
-Good heat resistance, less discoloration at high temperature than
galvanized steel.
-Good thermal reflectivity.
-Processability and spraying performance similar to galvanized
steel.
-Good welding performance.
-Good performance-price ratio, durable performance and extremely
competitive price.
