PPGL/ PPGI production process
PPGI stands for pre-painted galvanized steel coil. This is a material produced from galvanized steel that is then coated with a layer of paint on the surface. PPGI coil is commonly used in construction, roofing, wall cladding, and many other applications due to its durability, corrosion resistance, and high aesthetic appeal
PPGL stands for pre-painted galvalume steel coil. Similar to PPGI steel coils, this material is produced by galvanizing steel and then coating it with a layer of paint on the surface. This material has better corrosion resistance than regular galvanized steel, and is commonly used in construction, roofing, and other applications due to its durability and aesthetics.
The PPGI/PPGL production process is quite complicated and includes many steps. Next, let's learn about the production process with GNEE STEEL to produce PPGI/PPGL. The PPGI and PPGL production process includes the following steps:
- Material checking: Raw materials are carefully inspected before entering the production process.
- Surface finishing treatment: Steel needs to be cleaned to remove impurities and dirt, this is an important step to ensure the coating will adhere tightly to the product surface.
- Galvanized coating or galvalume coating: Once the surface has been cleaned, the steel is put through a galvanized or galvalume process. This plating layer has the effect of limiting corrosion of the product, helping to protect the product surface to the maximum.
- Anti-corrosion coating: After being coated with galvanized or galvalume, another anti-corrosion layer, usually a paint layer combined with antioxidants, is applied to the surface.
- Color coating: A color coating layer is applied to the plated and anti-corrosion coated surface. This process can be done using roll or spray painting methods.
- Collecting coils: After the color coating has been completed, the steel will be put into the furnace to dry the paint layer, then check and collect the coils.
