Product Description
Prepainted galvanized steel coils (ppgi) are one of the most popular types of steel coils used in the industry today. They are coated with a layer of zinc and then painted with a layer of paint on top. This gives them a very strong resistance to corrosion and makes them last longer than other types of steel coils. Paint is applied on top of the zinc coating to give the ppgi coil its color. The most popular colors used for ppgi coils are white, black, and gray. However, there are many other colors available as well. The paint used on ppgi coils is usually a polyester or acrylic based paint.

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).
