What is PPGL Coil Prepainted Galvalume Steel PPGL Coil

What is PPGL Coil Prepainted Galvalume Steel PPGL Coil?

 

PPGL coil and ppgl sheet full form Prepainted Galvalume Steel PPGL Coil is made of Hop dipped Galvalume/Aluzinc Steel Coil (55% aluminum, 43.5% zinc, and 1.5% silicon) which is more corrosion-resistant than galvanized as the substrate and has been surface degreased, phosphate and complexed. It is a product made after acid treatment, coating with organic paint and baking.

PPGL Coil

Prepainted galvalume steel coil consists of the top coating layer, primer coating, pre-treatment coating, Al-Zn coating, based metal sheet(cold rolled sheet), Al-Zn coating, pre-treatment coating, primer coating and the bottom coating.

Advantaged features of Prepainted galvalume PPGL coil .

1.Long warranty period
At present, the AZ100-150 warranty letter of 55% galvalume sheet promises 10-15 years of non-perforation (in the absence of obvious pollution), while ordinary color coated steel only issue a promise of 8-10 years of color warranty.

 

2.Good thermal insulation effect
The thermal effect value of 55% aluminum-zinc plate is very high, which can reflect 70% of the heat energy in the sunlight. Therefore, prepainted galvalume steel coilis used in roof and wall materials.

 

3.Environmental protection
It is directly used in construction, home appliances and other fields, replacing the traditional electroplating industry to a large extent. Prepainted galvalume steel coil has the perfect color, and is easy to recycle and use without pollution.

 

4.Good processing performance of molding and forming
prepainted galvalume steel coilcan be directly molded without damage, without paint peeling, paint peeling, paint touch-up and other color board processing and molding problems, which are widely used in interior decoration.

Price of Prepainted galvalume steel PPGL  coil

The main influencing factors on the price of color-coated steel plates are raw materials (substrate)  thickness, coating thickness, Painting Styles, packaging method and color, etc.

 

  1. Thickness of substrate steel coil

The thinner of substrate steel coil with the higher the price. Because the thinner the substrate steel coil, that more meters per ton and the larger the area. It will use more painting and take longer processing time.

  1. Thickness of Galvalume/Aluzinc coating

The price depends on the different thicknesses of the galvanlume/aluzinc layer. The thicker coating, will have higher price with the longer lifetime.

 

  1. Paint thickness

Generally speaking, the thickness of the top coat film of a single-sided color coating is 11-30um, and back paint is 5-10um. The thickness of the double-paint top coat is 11-30um and back coat is also 11-30um. The price of a single-sided color coating is lower than that of a double-layer color coating.

 

4Painting Styles

Mainly Painting Styles include: Polyester (PE), Silicone modified polyester (SMP), Highly durable polyester (HDP), Polyvinylidene fluoride or polyvinylidene difluoride (PVDF)

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.

 

5 Package

The packaging of Prepainted Galvalume steel PPGL 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.

FAQ of Prepainted Galvalume PPGL Coil

 1.What is PPGI and PPGL coil?
PPGI is short for pre-painted galvanized steel while PPGL is short for pre-painted galvalume steel. PPGI is made of galvanized sheets as base metal while PPGL is galvalume sheet as substrate(55% aluminum, 43.5% zinc, and 1.5% silicon).

2.Which are betterfor PPGI and PPGL Coil?
Although the price of the PPGL is 2%-3% higher than that of the PPGI, PPGL have better in heat reflectivity, heat resistance, corrosion resistance and service life.

3.Which brand paint do you use?
Nippon, Akzo-Nobel and KCC brand paint.

4. How thick is Aluzinc coating?

The Galvalume/Aluzinc Coating thickness form AZ40 to AZ150.
