In steel manufacturing, coating materials play a vital role. Among them, PPGI, PPGL and PPGF are very common types. They differ in composition, performance and application scenarios, so they are worthy of our in-depth understanding.
PPGI (pre-painted galvanized steel):
- It is a product with a zinc layer on the surface of the steel plate.
- This coating can provide good corrosion resistance, protect the steel plate from atmospheric corrosion and extend its service life.
- PPGI is commonly used in construction, home appliances, automobiles and other fields.
PPGL (pre-coated galvalume steel sheet):
- Similar to PPGI, PPGL is also a product coated with a zinc alloy layer on the surface of the steel plate, but unlike PPGI, its coating contains not only zinc but also aluminum.
- This gives PPGL better corrosion resistance and longer service life, making it suitable for harsher environmental conditions.
PPGF (Precoated Glass Fiber Reinforced Plastic):
- Unlike the first two, PPGF is a plastic material reinforced with glass fiber rather than steel plate.
- This material has excellent strength and corrosion resistance and is often used to manufacture ships, storage tanks, wind turbine blades and other products that require lightweight and high strength.
