What is PPGI Sheet In Coil?

PPGI Sheet are also called Pre-painted galvanized steel sheet in coil. Galvanized steel coils are used as the substrate..

They are treated on the surface by removing grease, cleaning, and applying chemicals. A product made by applying paint in a continuous method (roller coating), baking and cooling. Users can directly process the coil, which has a surface coating done in a factory, into products.

A zinc layer protects PPGI Sheet, which uses hot-dip galvanized steel coil as the base material. The organic coating on the zinc layer plays a covering and protective role to prevent the steel strips from rusting. The service life is longer than that of galvanized strips, about 1.5 times.

Production standards and materials of PPGI Sheet

Commonly used production standards and material information for PPGI Steel coils are as follows:

Categories and price of PPGI Sheet

The coated plate has the advantages of both organic polymers and steel plates. You can color, shape, and it is resistant to rust this material. It has a nice appearance similar to plastic.

Additionally, it is strong and easy to work with, similar to metal. It can be easily Carry out processing such as punching, bending, deep drawing, and welding. This makes products made of organically coated steel plates have excellent usefulness, decoration, processability and durability.

There are many varieties of Color coated steel sheet, about more than 600 types, but there is still no unified classification method, because it is difficult to find a standard to distinguish between the many varieties. At the same time, each manufacturer has its own unique equipment and processes, and there are many types of products.  Now we only classify them according to general habits.

1. Different techniques manufacture steel plates coated with organic material. It is have one coated and one baking, two coated with two Baking, Three coated with three Baking and four coated with four Baking technology..
2. According to different coating methods, there are organic coated steel plates made by roller coating, spray coating, powder method, lamination method, printing method, etc.
3. According to embossing or printing processing, it can be subdivided into wood grain board, marble grain, leather grain, cement mortar grain and other coated steel plates.
4. Painting Style:

Polyester (PE) exhibits excellent adhesion, a vibrant color range, extensive formability, and durability in outdoor conditions. It also offers moderate resistance to chemicals and is cost-effective.

Silicone modified polyester (SMP) possesses excellent hardness, resistance to abrasion and heat in the coating film. Outside, it has good durability, resists chalking, keeps gloss, is somewhat flexible, and has a moderate price.

Highly durable polyester (HDP) offers outstanding color stability and resistance to UV rays. It provides exceptional outdoor durability and resistance to chalking, along with excellent adhesion of paint film. It comes in a variety of vibrant colors and offers excellent value for money.

Polyvinylidene fluoride or polyvinylidene difluoride (PVDF) exhibits superior color retention and UV ray resistance. It boasts exceptional durability outdoors and resistance to chalking, as well as excellent resistance to solvents. It also has good formability and dirt resistance. However, it comes in limited colors and is relatively expensive.

The most commonly used coatings are PE, which have a relatively large price advantage. PVDF coatings, HDP coatings and SMP coatings have longer service life than PE coatings, but are more expensive. The paint brands we use include Nippon, Akzon-Nobel, KCC and so on. It is make ensure high-quality PPGI sheet  in coil.

Packaging of PPGI Sheet

The packaging of PPGI sheet in coil includes simple packaging, standard export package, Special Pakage.

Simple Package

A waterproof craft paper exterior safeguards basic packaging, which is ideal for short-range transport. It offers basic protection and is cost-effective.

Standard export package

3 layers of packing, inner side is anti-water craft paper, PVC plastic film is the middle and outer side covered by at least 0.45mm thick steel sheet, wrapped by minimum seven steel strapping strips with lock catch..

Special package

Special package includes vertical packaging or customer-required packaging. This packaging method can calculate the price based on the packaging cost. Vertical packaging is a roll with the core upward and the bottom fixed on a wooden pallet. This packaging method protects the steel coils from external forces to the greatest extent, but the packaging and labor costs are high.

Application of PPGI Sheet

PPGI Sheet in Coil are lightweight, beautiful and have excellent anti-corrosion properties, and can be processed directly. Commonly used colors are gray white, ocean blue and brick red. They are mainly used in the advertising industry, construction industry, home appliance industry, electrical appliance industry, furniture industry and transportation industry.

People Also Ask

What is the full form of the PPGI sheet?

The full form of PPGI sheet is “Pre-Painted Galvanized Iron Sheet” or “Pre-Painted Galvanized Steel sheet”.

What is the difference between PPGL sheet and PPGI sheet?

The difference between PPGL Sheet and PPGI Sheet mainly lies in the coating of the base material. The base material of PPGL sheet is Galvalume steel sheet. The base material of PPGI Sheet is galvanized steel sheet.

Which one is better for roofing, PPGI sheet or PPGL sheet?

PPGL sheet have better anti-corrosion and corrosion-resistant effects and have a longer service life than PPGI sheet.

They are very suitable as construction and facility materials in harsh environments. PPGL sheet will gradually enter more fields and get better applications
