PPGI/PPGL (pre-painted galvanized/galvalume steel coil) are two types of materials commonly used to construct buildings and structures. For each type of project, there will be different options.
In this article, MRS Steel will help you learn information about PPGI/PPGL and their advantages to help you make wise decisions for your construction project.
PPGI/PPGL are often used in construction projects
Some information about PPGI/PPGL
PPGI/PPGL is also known as color-coated steel. This type of steel is galvanized or galvalume and then coated with a layer of color plating on the outside. This color plating, in addition to increasing the aesthetics of the project, also reduces the ability to absorb heat from the sun. Currently, PPGI/PPGL is often applied in many fields in many industries.
What is PPGI?
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
What is PPGL?
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.
Therefore, in environments with harsh conditions and exposure to high salt concentrations, people often choose PPGL.
Differences between PPGI/PPGL

PPGI/PPGL production process
The PPGI/PPGL production process is quite complicated and includes many steps. Next, let's learn about the production process with MRS 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.

Advantages of Pre-painted/Color coated steel
Each type of material has its own advantages and disadvantages. To know why PPGI/PPGL is widely used in daily life, please join MRS Steel to learn about the advantages of PPGI and PPGL through the section below.
Corrosion resistance: PPGI/PPGL products are highly corrosion resistant thanks to being plated with a layer of galvanized or galvalume on the product surface. For particularly corrosive environments, PPGL is preferred over PPGI.
High aesthetics: Pre-painted/Color coated steel has quite high aesthetics because it is painted in many colors and patterns depending on the user needs. From there, it also contributes to increasing the aesthetics of your project.
High durability: In addition to being plated with an additional layer of paint to make the product more beautiful, PPGI/PPGL is made from galvanized steel and galvalume steel; these two materials are quite resistant to corrosion. This helps increase the durability of the product. Under normal conditions, the lifespan of PPGI and PPGL can last up to 50 years.

Application of PPGI and PPGL
Pre-painted/Color coated steel is commonly used in the construction industry. However, in addition to construction, PPGI/PPGL is also used in many different industries due to its durability, corrosion resistance and aesthetics. Below, join MRS Steel to learn about the applications of PPGI and PPGL.
Construction industry: PPGI/PPGL are often used as roofing sheets, partitions and wall cladding for buildings and structures. The material durability, corrosion resistance and aesthetics make it an attractive choice for architects and construction companies.
Automobile industry: For the auto industry PPGI and PPGL is used in the production of car bodies, spare parts and other auto components. The material rust resistance makes it ideal for the harsh conditions of the automotive industry.
Electrical industry: PPGI/PPGL color coating is used in the production of electrical appliances and devices such as refrigerators, air conditioners and washing machines. The material smooth surface and corrosion resistance make it ideal for these types of applications.
Furniture industry: For some furniture products that require sturdiness and aesthetics, this will be the top choice. Especially projects and products The material ability to withstand the elements and its attractive appearance make it a popular choice for furniture manufacturers.
Packaging industry: PPGI/PPGL is used in the production of cans and other packaging materials. The material corrosion resistance and strength make it ideal for packaging applications.
In Vietnam PPGI/PPGL is often used for roofing
