Prepainted Galvalume Steel Coil (PPGL)

Prepainted Galvalume expands on the corrosion resistance of standard Galvalume by adding a top coat of high-performance paint.

Characteristics of prepainted color-coated coil substrate

Hot-dipped aluminum zinc substrate:
This product is plated with 55% AL-Zn and has excellent anti-corrosion properties. Its service life is more than four times that of ordinary galvanized steel sheets. It is a replacement product of galvanized sheet.

Key types of colour-coating include

Polyester (PE)

Namely (PE), Good adhesion, rich colors, wide range in formability and outdoor durability, medium chemical resistance, low cost.

Silicon modified polyester (SMP)

Namely (SMP), the hardness, abrasion resistance and heat resistance of the coating film are good, as well as good external durability and chalking resistance, gloss retention, average flexibility, and medium cost.

High durability polyester (HDP)

Namely (HDP), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, good paint film adhesion, rich colors, and excellent cost performance.

Polyvinylidene fluoride (PVDF)

Namely (PVDF), excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited colors, and high cost.
