PPGI PPGL Color Coated Steel Coil Galvanized Steel Coil Color Coated Steel Coil Z275/Metal Roofing Sheets Building Materials
Pre-painted galvanized steel combines utility with beauty. It consists of tin, chrome, zinc or paint, which are the extra finish applied to the natural steel surface. The application of coating is to protect the surface of steel from oxidation and it is also used to enhance requirements for visual appearance.
Before we start discussing the difference between the two, it’s important you know what the terms “PPGI” and “PPGL” expand to. PPGI, which refers to Pre-painted galvanized iron steel. While PPGL stands for Pre-painted galvalume steel. Both of these steel variants are also known by the name of color coated steel in the industry.
So, what’s the difference between PPGI Steel Coil and PPGL Steel Coil ? Below we will show you an answer.
The primary difference between the two types of steel coil is in the coating applied to each variant. PPGI or pre-painted galvanized iron steel coil is evenly covered with a layer of zinc. The zinc coating provides anodic protection to the base material, prolonging the product’s service life.
PPGL or pre-painted galvalume steel coil, on the other hand, is coated with a mix of aluminum, zinc and other trace elements. The usual composition of galvalume coating is 55% aluminum, 43.4% zinc and 1.6% trace elements.

Pre-painted Hot-dip Galvanized Steel Coil
Application of PPGI PPGL steel coils :
Pre-painted steel coils are used in roof structure, surface sheet of balcony, frame of window, folding screen and electrical equipment. Pre-painted steel can be formed into almost any shape, and it has excellent resistance to weathering, superior longevity and texture options.
Color coated steel coil/sheet (PPGI & PPGL) is widely used in:
- Building
- Roofing
- Transport
- Home Appliances, such as the side door plate of refrigerators, shell of DVDs, air conditioners and washing machines.
- Solar Energy
- Furniture
PPGI (Pre-Painted Galvanized Iron) steel coils are versatile materials with wide-ranging applications across numerous industries.
They are particularly favored for their corrosion resistance, aesthetic appeal, and ease of processing.
Construction: PPGI coils are extensively used in construction for roofing, wall panels, siding, and structural components like beams and columns. They offer durability, weather resistance, and can be customized in various colors and finishes.
Residential: PPGI is used for roofing, fencing, and decorative elements in residential buildings.
Commercial and Industrial Buildings: Applications include roofing, wall cladding, and interior design elements in commercial and industrial structures.
Agricultural: PPGI coils are utilized in agricultural buildings, such as sheds and greenhouses, due to their resistance to
environmental factors.
Home Appliances: The appliance industry uses PPGI for refrigerators, washing machines, microwave ovens, and other white and brown goods.
Automotive Industry: PPGI can be found in automotive parts, both exterior and interior, due to its strength and formability.
Signage: PPGI is a popular choice for signage and advertising displays due to its ability to be easily shaped and painted with various colors.
