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.
Standard Ral Colors:
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.
