Color Coated Galvanized Steel Coil PPGI

PPGI is a product that uses hot-dip galvanized sheets, hot-dip galvalume sheets, electro-galvanized sheets, etc. as substrates. After surface pretreatment, one or several layers of organic coatings are coated on the surface, and then baked and solidified. Colored steel coils are named after being coated with organic coatings of various colors, referred to as color-coated steel coils.

Hot Dip Galvanized PPGI Steel

Mainly use hot-dip galvanized steel sheet as the substrate, due to the protection of zinc layer and organic coating, its service life is longer than hot-dip galvanized sheet. The available zinc layer is 275g/m2.

Electro-galvanized PPGI Steel

An electrogalvanized sheet was used as the substrate. Because the zinc layer of electrogalvanized sheet is thin, usually 20g/㎡, its corrosion resistance is not as good as that of hot-dip galvanized sheet. Therefore, the product is not suitable for making outdoor walls and roofs. But it has a beautiful appearance and excellent processing performance, mainly used for home appliances, steel furniture, interior decoration, etc.

PPGI Color Coating Coil Advantages

Color coated galvanized coil has a variety of colors and patterns to meet different styles and uses. The colorful coating also makes PPGI steel more resistant to corrosion and durable. PPGI steel coil has excellent processing performance. So you can make the coil into different products according to your needs. The color coated galvanized steel coil also retains the strength of the steel, making it tough and safe. The PPGI coated coil is light in weight and easy to transport and install. Compared with PPGL steel, the price is more affordable.

Surface Treatment
Laminated Film
The process is to coat a transparent organic film (30-50 µm) on the steel coil at high temperature. It has some unique properties, such as fire resistance, fingerprint resistance, excellent durability, anti-fouling ability, etc. Obviously, this treatment method can protect the steel coil well during storage and transportation.
Embossing
Embossed PPGI steel coil design has different patterns. Popular patterns are stucco, rhombus, etc. And it’s customizable. Compared with the smooth steel coil, it has a vivid 3D effect.
 

Coating Type

In the coil coating, the durability of the role is the resin and pigment, the most commonly used finish polyester, silicon modified polyester, high durability polyester and polyvinylidene fluoride.
Polyester PE
Good adhesion, rich color, wide range in formability and outdoor durability, medium chemical resistance, low cost.
Silicon Modified Polyester SMP
The hardness, abrasion resistance and heat resistance of the coating film are good; as well as good external durability and powder resistance, gloss retention, general flexibility and medium cost.
High Durability Polyester HDP
Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good 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 formability, dirt resistance, limited color, and high cost.
