PPGI roof

01. SMOOTHNESS
No composite indentation, no residual stress, no deformation after shearing.
02. DECORATIVE
You can choose a realistic material and aesthetic wood grain, stone coating. Patterns and colors can be customized according to
customer requirements.
03. DURABILITY
Surface paint, high gloss retention, good color stability, minimal change in chromatic aberration, and long service time.
04. STABILITY
The change of wind pressure, humidity and temperature will not cause bending, deformation and expansion. It has strong bending and flexural resistance.

Hot-dip galvanized PPGI steel

Hot-dip galvanized steel sheets are mainly used as the base material. Due to the protection of zinc layer and organic coating, its service life is longer than that of hot-dip galvanized sheets. Available zinc layer is 275 g/m².

Electro-galvanized PPGI steel

Electro-galvanized sheet is used as the base material. Since the zinc layer of electro-galvanized sheets is thin, usually 20g/㎡, its corrosion resistance is not as good as that of hot-dip galvanized sheets. This product is therefore not suitable for outdoor walls and roofs. But it has beautiful appearance and excellent processing performance, and is mainly used in home appliances, steel furniture, interior decoration, etc.

Selection of color

We offer a wide range of colors to choose from, the following are the common colors, if you like other colors or patterns, please send us the RAL color code.

Advantages of PPGI color coated rolls

Color-coated galvanized coil sheets are available in a variety of colors and patterns to meet different styles and uses. The colorful coating also makes PPGI steel more corrosion-resistant and durable. PPGI steel coil has excellent processing properties. So you can make the coils into different products depending on your needs. Color-coated galvanized steel coils also retain the strength of the steel, making it tough and safe. PPGI coated membranes are lightweight and easy to transport and install. Compared with PPGL steel, the price is more affordable.

Surface treatment
Lamination
This process is to apply a transparent organic film (30-50㎛) on the steel coil at high temperature. It has some unique properties such as fire resistance, fingerprint resistance, excellent durability, stain resistance, etc. Obviously, this treatment method can protect the steel coil well during storage and transportation.
Embossed
Embossed PPGI steel coils are designed with different patterns. Popular patterns are stucco, diamond, etc. And it's customizable. Compared with smooth steel coils, it has a vivid 3D effect.

Coating type

In coil steel coatings, resins and pigments play a role in durability. The most commonly used topcoats include polyester, silicon-modified polyester, high-durability polyester and polyvinylidene fluoride.
Polyester PE
Good adhesion, rich colors, broad range in formability and outdoor durability, moderate chemical resistance, low cost.
Silicone modified polyester SMP
The coating film has good hardness, abrasion resistance and heat resistance; as well as good external durability, chalking resistance, gloss retention, average flexibility and medium cost.
High durability polyester 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
Excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, stain resistance, limited colors, high cost.

Application scope
