GALVANIZED COLOR COATED SHEET PPGI

Prepainted galvanized sheet PPGI is made of hot-dip galvanized sheet, electro-galvanized sheet, etc. as the substrate. After surface pretreatment, it is coated with one or more layers of liquid coating by roller coating, and then baked and cooled. The surface is rich in color, has good weather resistance, and has excellent processing performance.

Prepainted sheets can be divided into ordinary PE, high corrosion resistance HDP, high corrosion resistance silicon modified polyester SMP, high corrosion resistance fluorocarbon PVDF, super corrosion resistance nano fluorocarbon PVDF, aluminum magnesium manganese prepainted sheet, printed prepainted sheet, etc.

ADVANTAGES OF PREPAINTED SHEETS

Customized color

You can choose any RAL color, or customize the pattern as needed. The beautiful surface makes the prepainted sheet decorative. So it can be directly used in many fields.

Tough Sotin

Prepainted steel sheets include PPGL sheet PPGI steel, which adopts continuous coil coating, and the surface is bright and shiny, without cracking or peeling. In addition, it can maintain the color for at least 10 years.

Excellent mechanical properties

Prepainted sheets retain the mechanical properties of the parent material, such as tensile strength. In addition, the application of coating can protect the surface from rust, thereby extending its service life. Studies have shown that the service life of color-coated steel is 50% longer than that of galvanized steel.

COATING TYPES

In coil coatings, the role of durability is the resin and pigment, and the most commonly used are topcoat polyester, silicon-modified polyester, high-durability polyester, and polyvinylidene fluoride.

Polyester PE

Good adhesion, rich colors, a wide range of formability and outdoor durability, medium chemical resistance, and low cost.

Silicon-modified polyester SMP

The hardness, wear resistance, and heat resistance of the coating film are good; as well as good exterior 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 powder resistance, good film adhesion, rich colors, and excellent cost performance.

Polyvinylidene fluoride PVDF

Excellent color retention and UV resistance, excellent outdoor durability and powder resistance, excellent solvent resistance, good formability, stain resistance, limited colors, and high cost.
