Product Details

Color Coated Steel Coils PPGI Prepainted Steel Coil Metal Roll Paint

Differences between PPGI and PPGL

1. Corrosion resistance:

Aluminized zinc has a stronger protective effect and better corrosion resistance than galvanized products. The corrosion resistance of the "55% aluminium-zinc plated steel coil" comes from the barrier protection function of aluminium and the sacrificial protection function of zinc. When zinc makes sacrificial protection in the cutting, scratch and coating scratch parts, aluminium forms an insoluble oxide layer to play the function of barrier protection.

2. Heat resistance:

The heat resistance of 55% Al Zn alloy steel plate is better than that of galvanized steel plate, which is similar to that of PPGI. PPGL steel plate can be used in high-temperature environments up to 315 ℃.

3. Reflectivity:

55% Al Zn alloy plated steel plate has high reflectivity, making it a heat resistant barrier; The thermal reflectivity of PPGL is almost twice that of PPGI. Therefore, it can also achieve an energy-saving effect by acting as a roof and panel without painting.

4. Paintability:

Due to the excellent adhesion between the zinc layer of PPGL and the paint, when used as a signboard for general purposes, it can be painted without pretreatment and weathering treatment; PPGI needs weathering treatment and pretreatment. So that the surface of the PPGL sheet is smoother than that of the PPGI sheet.

Resistance to acid rain:
Coating protection mechanism: It is very easy to form acid rain in the high level of industrial emissions or pollutants environment. Acidic penetration is formed in the surface of pre-painted steel, and accelerates the corrosion, forming blistering, peeling and so on.
Resistance ultraviolet rays:
Coating protecting Mechanism: pre-painted sheet in ultraviolet or strong sunlight conditions, the coating will exhibit chalking degeneration, manifested as discoloration and loss of gloss, lose paint quickly.
Resistance to humid heat:
Coating protecting mechanism: in hot and humid environments, high osmotic pressure of water vapor accelerates penetration, forming the degeneration of painting film, then the corrosion of the substrate, with the phenomenon of bubbles and peeling.
Resistance to low temperature:
Coating protecting mechanisms: most of the paint can keep stable processing performance above 0 degree, but at alpine region, the temperature will be below 20-40 degree, normal paint will become brittle,bend cracking, or even lose paint, thus protection function is lost totally.

Pre-painted metal is a metal on which a material such as paint has been applied by the coil coating process to form a

protective film. Coil coating is a continuous process in which a coil of metal (steel or aluminum are common substrates)

is unwound and both the top and bottom surfaces are cleaned, chemically treated, and then primed and /or painted and

oven cured. A wide range of coatings are in use, developed in order to provide different levels of durability and performance and to satisfy distinct aesthetic requirements.

Applications of Prepainted steel coil

1. Construction and building: roofing; ventilating duct; handrail; partition panel;etc.
2. Electric appliance: refrigerator; washing machine; refrigerator; DVD;etc.
3. Transportation: oil tank; road sign; etc.
4. Agriculture:barn; etc.
5. Others:vending machine; game machine; etc.

Quality Control:

The pre-painted galvanized steel coils are a product obtained by subjecting a hot-dipped galvanized steel sheet to a surface chemical treatment, applying organic coating on the surface, followed by baking and curing.

PPGI steel coil is a popular material for roofing sheets, wall panels, furniture, home appliances, automobile uses, etc. It keeps the strength of galvanized steel. Meanwhile, the organic coating offers various colors and attractive appearance.
