Color Coated Steel Coil
Prepainted Steel Coil
The prepainted steel sheet in coil is a product obtained by subjecting a hot-dipped galvanized steel sheet, and galvalume steel sheet, or an aluminum sheet to a surface chemical treatment (coating), followed by baking and curing.
The total thickness of the pre-panted galvanized steel coil is composed of the base steel – coating -primer – top paint – protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm. The thinner the base

PPGI Coil Price Reference
The prepaint galvanized steel coil prices keep changing, which is calculated based on raw material(Hot rolled sheet), width, thickness, paint, and zinc. Here is the only reference price, Please email us to get the precise price.
PPGI Sheet
The decoiler machine unwinding, leveling, fixed-length, cut the prepainted galvanized steel coil into a flat PPGI sheet of the required length and width and is processed into a PPGI roofing sheet of various styles by a roll forming machine, such as corrugated steel sheet, wave tile, roman longtime profile.
Type Of Coating
The coating types currently used for PPGI/PPGL steel coil include PE, PVDF, SMP, acrylic, PVC, etc.
PE
The PE-coated color-coated steel sheet is easy to be processed and formed because of its good adhesion, and the price is relatively cheap. But the other degree of UV resistance and chalking resistance is relatively low. PE color coated steel can be used for the roof of ordinary civil buildings.
SMP
SMP steel plate has better durability, and the cost is higher than the PE coating. Silicone is not as good as PE in terms of adhesion and processing formability to materials,
High Durable Polyester (HDP)
It is better than ordinary SMP coatings, and its outdoor weather resistance reaches 16 years. Its flexibility and weather resistance are higher.
PVC
PVC coating has nice anti-chemical and anti-water, and the coasting is relatively thick, which can well protect the substrate.
The PVC coating is rarely used because they pollute the environment.
PVDF
PVDF coatings have great color retention and corrosion resistance. Among the PPGI sheet coating for construction, it is the highest grade.
Acrylic
The comprehensive performance is good, the price is expensive, and it is only used in specific fields (such as containers).
Prepainted Steel FAQ
The Reasons For The Color Difference Of The PPGI Sheet:
The color difference of the paint itself;
The drying process;
Paint coating thickness;
Glossy of paint;
How To Choose Prepainted Steel Coil
Choosing a prepainted steel coil needs to consider the natural environment, use environment, design life, and structural characteristics of the building to match the appropriate steel grade, specifications, Metallic coating, and coating.
The performance of color coated steel sheet mainly includes the mechanical properties of the material (tensile strength, yield strength, elongation), Metallic coating performance (Metallic coating type, thickness, and adhesion), and coating performance (coating species, color, gloss, durability, Processability, etc.)
The main consideration for the selection of color-coated steel sheets in different regions is the local wind and snow load and corrosive environment.
Non-ferrous metal smelters (zinc, copper, lead, etc.) are the most challenging service life of color coated steel.
The beauty and durability of civil buildings are the primary considerations for the prepainted steel sheet. Therefore, it is very important that the coating resists discoloration, pulverization, and the coating surface is complete and fin
