PPGI is pre-painted galvanised iron, also known as pre-coated steel, coil coated steel, color coated steel etc., typically with a hot dip zinc coated steel substrate.

The term is an extension of GI which is a traditional abbreviation for Galvanized Iron.

Today the term GI typically refers to essentially pure zinc (>99%) continuously hot dip coated steel, as opposed to batch dip processes. PPGI refers to factory pre-painted zinc coated steel, where the steel is painted before forming, as opposed to post painting which occurs after forming.

The hot dip metallic coating process is also used to manufacture steel sheet and coil with coatings of aluminium, or alloy coatings of zinc/aluminium, zinc/iron and zinc/aluminium/magnesium which may also be factory pre-painted. While GI may sometimes be used as a collective term for various hot dip metallic coated steels, it more precisely refers only to zinc coated steel. Similarly, PPGI may sometimes be used as a general term for a range of metallic coated steels that have been pre-painted, but more often refers more precisely to pre-painted zinc coated steel.

Zinc coated steel substrate for PPGI is typically produced on a continuous galvanizing line (CGL). The CGL may include a painting section after the hot dip galvanized section, or more commonly the metallic coated substrate in coil form is processed on a separate continuous paint line (CPL). Metallic coated steel is cleaned, pre-treated, applied with various layers of organic coatings which can be paints, vinyl dispersions, or laminates. The continuous process used to apply these coatings is often referred to as Coil Coating.

Manufacture process:

It is a prepainted, prefinished and ready for further processing into finished products or components to use material.

Pre-Painted Galvanized Steel Coil(PPGI) Industry knowledge

What is the role of Pre-Painted Galvanized Steel Coil (PPGI) in the transportation industry?

Pre-Painted Galvanized Steel Coil (PPGI) plays an important role in the transportation industry. The following are the main roles of PPGI in the transportation industry:
Vehicle manufacturing and decoration: PPGI is widely used in the manufacturing of cars, trucks, buses and other transportation vehicles. It can be used as an exterior covering material for car bodies, providing a beautiful appearance and excellent corrosion resistance. PPGI’s colorful coatings not only add appeal to vehicles, they can also be customized as needed to achieve different designs and branding.
Carriage and container manufacturing: In the fields of railway transportation and shipping, PPGI is often used to manufacture the shells of train carriages, containers and other transportation tools. Its rugged and durable features can withstand severe weather and collisions during transportation, ensuring the safe transportation of goods.
Vehicle interior components: In addition to exterior covering materials, PPGI can also be used to manufacture certain components inside vehicles, such as interior panels, partitions, etc. Its smooth surface and corrosion resistance make it suitable for use where beauty and durability are required.
Weather Resistance and Safety: PPGI’s weather resistance enables it to maintain its appearance and performance for extended periods of time in outdoor environments. In the transportation industry, this means vehicles and vehicles can operate in a variety of climate conditions without fear of corrosion or damage to materials. In addition, PPGI's ruggedness also contributes to the overall safety of the vehicle.
Cost-Effectiveness: Compared with other materials, PPGI has relatively low manufacturing costs and maintenance costs. This makes it a cost-effective option in the transportation industry, especially for large-scale production and batch manufacturing.
To sum up, Pre-Painted Galvanized Steel Coil (PPGI) plays an important role in the transportation industry, providing reliable solutions for the manufacturing, decoration and safety of vehicles and transportation vehicles.
