PPGI and PPGL are both types of pre-painted galvanized steel

PPGI and PPGL are both types of pre-painted galvanized steel. The difference is in the coating that each has. PPGI is coated with zinc, while PPGL is coated with a mixture of aluminum and zinc.
PPGI is made by applying one or several layers of organic coating to cold-rolled or galvanized steel. This is done through a continuous process that involves chemical pretreatment, coating, baking and cooling.
Cost
PPGI and PPGL are two types of steel coils that are used in many applications. They are similar in that they keep the strength of galvanized steel and add a layer of organic coating to protect it from corrosion. Both are popular choices for roofing sheets and wall panels, furniture, home appliances, and automobile components.
Compared to traditional galvanized steel, PPGL performs better in harsh outdoor environments. It has good heat resistance and a dense aluminum layer that helps prevent erosion. Its durability also makes it a popular choice for ovens and chimney pipes. The only drawback is that the cut edges are not as protected and require a coating to prevent rusting.
Besides the RAL color series, PPGI & PPGL can be produced with different patterns, such as wood grain, camouflage, brick, and flower pattern. Some of these patterns are more popular in fencing applications, while others are used for building materials. You can choose one according to your requirements.
Durability
PPGI and PPGL steel coils are durable construction materials that can be used for a variety of applications, including wall panels and roofing. Unlike traditional steel, they are less likely to rust and are a good choice for environments that experience high temperatures or cold conditions. They can also be used for a variety of other applications, such as ventilation ducts, equipment hoppers, and various stamping parts.
Depending on the application, PPGL and PPGI are available in different coating structures. Those with 2/1 structure are suitable for sandwich panels and high-durability roofs, while those with 2/2 structure are ideal for walls and partitions.
PPGI and PPGL are both galvalume-coated steels that have a combination of zinc, aluminum, and trace elements like silicon. They can be used in both hot and cold regions, but PPGL is more resistant to corrosion than PPGI. The aluminum-zinc coating on PPGL provides better protection against corrosion than the zinc on a galvanized steel sheet, but it is still prone to rust on cut edges.
Corrosion resistance
PPGI PPGL steel coil are corrosion-resistant, which makes them ideal for outdoor applications. They have a zinc and aluminum coating that protects them from harsh weather conditions. The aluminum-zinc alloy provides superior heat resistance, which allows PPGL to last three times longer than zinc-only galvanized steel.
The corrosion resistance of PPGI PPGL coils depends on the thickness of the coating. The appropriate coating thickness should be confirmed based on environmental corrosivity, service life and durability.
PPGI is also known as pre-coated steel or color coated steel, and it can be used in many different applications. It is usually made from hot-dip galvanized steel or electro-galvanized steel sheets as substrates, and it has a light weight, beautiful appearance and good corrosion resistance. It can be directly processed and is available in a variety of colors. It is often used for advertising, construction, household appliances, furniture and transportation industry. Compared to other steel coils, it has the advantages of high corrosion resistance, oxidation resistance and weldability.
Appearance
PPGI & PPGL are widely used in building, product packaging and household manufacturing. They are light in weight, beautiful in appearance and have good corrosion resistance. However, it is important to choose the right PPGI & PPGL sheet for your application based on its production organization, color, use time and use environment.
Generally, a PPGI & PPGL sheet is made from annealed cold rolled steel coil and then Chromated. It is then coated with zinc, forming galvanized steel. After this, it is re-Chromated and then painted with an organic coating.
PPGI & PPGL sheets are usually available in various colors, including gray, sea blue and brick red. They can also be printed with different patterns, such as camouflage, wood grain, flower print and brick. Their appearance is appealing to contractors, and they can be a great choice for construction projects. They also provide a protective layer to prevent rust and moss from growing on the surface.
