Introduction
Color-coated coil is a product of hot galvanized plate, hot aluminum plated zinc plate, electrogalvanized plate, etc., after surface pretreatment (chemical degreasing and chemical conversion treatment), coated with one or several layers of organic coating on the surface, and then baked and cured. Because coated with a variety of different colors of organic paint color steel coil named, referred to as color coated coil.
Color-coated roll has light weight, beautiful appearance and good corrosion resistance, but also can be directly processed, the color is generally divided into gray, blue, brick red, mainly used in advertising, construction, home appliance industry, electrical appliance industry, furniture industry and transportation industry.

Color-coated Steel Coil Substrate Classification:
There are three main types of color-coated coil substrate: hot galvanized substrate, hot aluminized zinc substrate and electroplated zinc substrate. Hot-dip galvanized substrate is prepared by dipping hot-dip galvanized sheet into hot-dip galvanized solution and forming zinc coating on its surface. Hot plated aluminum zinc substrate is made by hot dipping a mixture of zinc and aluminum (such as 55% aluminum and 45% zinc) in hot plated aluminum zinc solution on the hot galvanized substrate, and then baking and curing the hot galvanized substrate after hot dipping.
Color-coated Steel Coil Coating Structure:
Color coated coil coating structure is mainly divided into two types: 2/1 and 2/1M. 2/1 coating structure refers to the upper and lower surfaces are coated twice and baked twice. 2/1M coating structure refers to the upper and lower surfaces are coated twice and baked once. The choice of coating structure depends on the environment and application.
Color-coated Steel Coil Advantages
1. Corrosion Resistance
The aluminum-zinc alloy coating provides excellent protection against corrosion even in highly corrosive environments near coastlines or industrial areas.
2. Durability
When combined with a durable paint finish, PPGL steel sheets can last over 25 years with only nominal maintenance under normal weather conditions.
3. Strength and Support
PPGL steel is strong yet lightweight. It can support heavy loads and withstand high wind loads making it suitable for roofing and cladding applications in commercial buildings.
Color-coated Steel Coil Applications:
1. Roofing
PPGL steel is widely used for roofing purposes in industrial, commercial and residential construction due to its corrosion resistant properties and durability.
2. Cladding
The material is also commonly applied as exterior wall cladding/facades thanks to the long lasting color coated finishes that retain aesthetics over decades.
3. Rainwater Goods
PPGL profiles are commonly used to manufacture rain gutters, downpipes, flashings and other rainwater accessories around buildings.
4. Industrial Siding
PPGL panels are a practical choice for warehouses, factories, agricultural sheds due to their non-combustible properties and ability to withstand impacts.
5. Agricultural Buildings
Farm buildings like sheds, barns and stables can be economically constructed using PPGL sheets that withstand all weather conditions.
Standard Seaworthy Export Packing:
Color-coated coils are typically packed and shipped in a way that ensures their protection during transportation and handling. Common types of packing include coil packaging with edge protectors and VCI (volatile corrosion inhibitor) paper, followed by secure bundling with steel straps or wrapping with plastic film.
