Product Description

Product Description

 

PPGI coil is based on hot-dip galvanized sheet, hot-dip aluzinc sheet, electro-galvanized sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then A product that is baked and cured. It is named after the colored steel coils coated with various colors of organic coatings, referred to as color-coated coils
The color-coated steel strip using hot-dip galvanized steel strip as the base material is not only protected by the zinc layer, but the organic coating on the zinc layer plays a covering and protective role to prevent the steel strip from rusting, and its service life is longer than that of the galvanized strip, about 1.5 times.

Color-coated rolls are light, beautiful, and have good anti-corrosion properties, and can be processed directly. The colors are generally gray, sea blue, and brick red. They are mainly used in advertising, construction, household appliances, electrical appliances, furniture, and transportation. Industry.

The coating used for color-coated coils should select appropriate resins according to different use environments, such as polyester silicon-modified polyester, polyvinyl chloride plastisol, polyvinylidene chloride, etc. Users can choose according to the purpose

Coating structure type:

2/1: Coat the upper surface twice, coat the lower surface once, and bake twice.
2/1M: Coat the upper and lower surfaces twice and bake once.
2/2: Coat the upper and lower surfaces twice and bake twice.

Application of different coating structures:

The corrosion resistance and scratch resistance of the single-layer back paint are poor, but it has good adhesion.
to be applied to sandwich panels;

The back paint has better corrosion resistance, scratch resistance and formability, and has good adhesion
Suitable for single-layer profiled panels and sandwich panels.

The corrosion resistance, scratch resistance and processability of the double-layer back paint are better, and most of them are used for single
Laminated panels, but their adhesion is poor, not suitable for sandwich panels

Coating Types of Prepainted Coils

Polyester (PE)
Good adhesion, rich colors, wide range in formability and exterior durability, moderate chemical resistance, low cost.

Silicon modified polyester
That is (SMP), the coating film has good hardness, wear resistance and heat resistance, as well as good external durability and chalking resistance, gloss retention, general flexibility, and medium cost.

High Durability Polyester
That is (HDP) excellent color retention and anti-ultraviolet performance, excellent outdoor durability and chalking resistance, good adhesion of the paint film, rich colors, excellent cost performance.

Polyvinylidene fluoride
That is (PVDF) excellent color retention and UV resistance, excellent outdoor durability and chalking resistance, excellent solvent resistance, good formability, dirt resistance, limited color, high cost.

Our Advantages

 

Color coated roll substrate classification

Hot-dip galvanized substrate
The product obtained by coating the organic coating on the hot-dip galvanized steel sheet is the hot-dip galvanized sheet. In addition to the protective effect of zinc, the organic coating on the outer surface also plays the role of isolation protection and preventing rust. The service life is longer than that of the hot-dip galvanized sheet. longer. The zinc content of the hot-dip galvanized substrate is generally 180g/m2 (double-sided).
The highest is 275g/m2.

Hot-dip galvalume substrate
Use hot-dip aluminum-zinc steel sheet (55%AI-Zn) as the newly coated substrate, usually with an aluminum-zinc content of 150g/m (double-sided). The corrosion resistance of hot-dip galvanized sheet is 2 to 5 times that of hot-dip galvanized sheet. Continuous or intermittent use at temperatures up to 490°C without severe oxidation or scale formation. The ability to reflect heat and light is twice that of hot-dip galvanized steel, and the reflectivity greater than 0.75 is an ideal building material for saving energy.

Color coated roll substrate characteristics

Hot-dip galvanized substrate:
The thin steel plate is immersed in a molten zinc tank to make a layer of zinc adhere to the surface. This galvanized sheet has good paint adhesion and weldability.

Hot-dip galvalume substrate
The product is plated with 55% AL-Zn and has excellent anti-corrosion performance. Its service life is more than four times that of ordinary galvanized steel sheets. Is the replacement product of galvanized sheet

PPGI Features:
(1) It has good durability and corrosion resistance, which is comparable to that of galvanized steel sheets.
longer than lifespan;
(2) It has good heat resistance and is less likely to change color at high temperatures than galvanized steel sheets
(3) Has good heat reflectivity
(4) It has the processing performance and sprayability similar to that of galvanized steel sheet able
5) Has good welding performance
It has a good performance-price ratio, durable performance and very competitive price. Therefore, whether it is architectural designers, engineers or manufacturers, galvanized steel sheets have been widely used in industrial buildings, steel structures and civil facilities, such as: garage doors, gutters and roofs, etc.
