Distinguish between Prepainted Galvanized Steel and Color Coated Galvalume Steel Coil
Prepainted Galvanized Steel (PPGI) and Color Coated Galvalume Steel Coil (PPGL) are both pre-painted steel products, but they differ in terms of the base metal they are made from. Here's a comparison between PPGI and PPGL(Color Coated Galvalume Steel Coil)
Base Metal
PPGI: PPGI is made from a base metal of galvanized steel, which is carbon steel that has been coated with a layer of zinc. The zinc coating provides excellent corrosion resistance to the underlying steel substrate.
PPGL: Color Coated Galvalume Steel Coil is made from a base metal of Galvalume Steel, which is a zinc-aluminum alloy-coated steel. The coating on galvalume steel consists of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This zinc-aluminum alloy provides enhanced corrosion resistance compared to traditional galvanized steel.
Corrosion Resistance
PPGI: PPGI offers good corrosion resistance due to the zinc coating on the steel substrate. The zinc functions as a sacrificial layer, shielding the steel underneath from corrosion. However, in highly corrosive environments or exposure to harsh elements, the zinc coating on PPGI may degrade over time.
PPGL: Color Coated Galvalume Steel Coil outperforms PPGI in terms of corrosion resistance. The addition of aluminum in the coating forms a protective barrier that enhances the resistance to corrosion. The aluminum in the zinc-aluminum alloy coating provides self-healing properties, further protecting the underlying steel from corrosion.
Alloy Composition
PPGI: The zinc coating on PPGI typically ranges from 80 to 275 grams per square meter. The thickness of the zinc coating affects the durability and longevity of the corrosion protection.
PPGL: Color Coated Galvalume Steel Coil zinc-aluminum alloy coating on Color Coated Galvalume Steel Coil consists of approximately 55% aluminum, 43.5% zinc, and 1.5% silicon. This composition enhances the corrosion resistance and offers improved durability in challenging environments.
Applications
PPGI: PPGI is commonly used in applications where corrosion resistance and cost-effectiveness are essential factors. It is widely employed in roofing, cladding, garage doors, appliances, automotive components, and general construction.
PPGL: Color Coated Galvalume Steel Coil is preferred in applications where superior corrosion resistance and extended durability are required. It is often used in environments with high humidity, coastal areas, and industrial settings. Color Coated Galvalume Steel Coil finds applications in roofing, cladding, agricultural buildings, outdoor infrastructure, and other applications that demand enhanced protection against corrosion.
