1. Base Material: PPGL coils are made from either galvanizedsteel (GI) or galvalume steel (GL). Galvanized steel is coated with zinc, whilegalvalume steel is coated with a combination of zinc and aluminum.
2. Preparation: Before coating, the steel undergoes surfacepreparation, including cleaning and chemical treatment, to ensure properadhesion of the coating.
3. Coating: PPGL coils are coated with a layer of paint orresin. This coating serves multiple purposes:
Protection: Itprotects the underlying steel from corrosion and other environmental damage.
Aesthetics: Thecoating provides a decorative finish, available in a wide range of colors andfinishes.
Durability: Thecoating enhances the durability and lifespan of the steel, making it suitablefor various applications.
4. Types of Coatings:
Polyester (PE)
Silicon ModifiedPolyester (SMP)
High-DurablePolyester (HDP)
PolyvinylideneFluoride (PVDF)
Others: Somespecialty coatings may offer specific properties like anti-graffiti orself-cleaning.
5. Applications :
Roofing: PPGLcoils are commonly used for roofing panels due to their weather resistance andaesthetic appeal.
Cladding: Theyare also used for wall cladding in commercial and industrial buildings.
Appliances: PPGLcoils find applications in manufacturing appliances like refrigerators andwashing machines.
Automotive: SomePPGL variants are used in automotive manufacturing for body panels and othercomponents.
6. Advantages:
CorrosionResistance: The zinc/aluminum coating provides excellent corrosion resistance,extending the lifespan of the steel.
AestheticOptions: PPGL coils offer a wide range of colors and finishes, allowing forcustomization to suit different architectural styles and preferences.
Formability: PPGLcoils can be formed into various shapes and profiles without compromising theintegrity of the coating.
Sustainability:The use of steel, along with its recyclability, makes PPGL coils a sustainablechoice for construction and manufacturing.
7. Quality Standards : PPGL coils are manufactured to meetspecific quality standards set by regulatory bodies and industry organizationsto ensure consistency and performance.
Overall, PPGL coils offer a versatile solution for various applications,combining the strength and durability of steel with the aesthetic andprotective properties of the coating.
