Details of PPGL 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 steel thickness, the higher the price of the ppgi steel coil, because the processing cost becomes higher.
Usually, the paint coating material is polyester (PE) and the color of the back paint is white grey. The color can be customized according to the RAL color card or customer samples. Special patterns can be made, such as wood grain, flower print, camouflage, brick.

1) PPGI is also known as prepainted galvanized steel coil and color coated steel coil, with a hot dip zinc coated steel sheet substrate.

2) PPGL is also known as prepainted galvalume steel coil, with a galvalume steel sheet as a substrate.

Mechanical Properties Of The Substrate

Mechanical properties of PPGI(pre-painted galvanized) steel coil substrate.

Substrate Selection

The substrate of the prepainted steel coil has a cold-rolled substrate, hot-dipping galvanized substrate and, aluzinc substrate.

Cold-Rolled Steel Substrate

prepainted steel sheets produced from cold-rolled substrates have the processing properties of cold-rolled sheets.

If the coating is scratched, the cold-rolled substrate will be directly exposed and will quickly rust. It can only be used for temporary barriers that are not demanding. It has the lowest price and is not recommended for civil buildings.

Hot-Dipping Galvanized Steel Substrate

In addition to the protective effect of zinc, the prepainted galvanized steel sheet also has coating protection, and the service life is longer than that of the hot-dipping galvanized steel sheet.

Hot-Dipping Galvalume Steel Substrate

Hot-dipping galvalume steel (55% AI-Zn) is used as the prepainted galvalume steel coil substrate.

The corrosion resistance of hot-dipping galvalume steel sheets is 2 to 5 times that of hot-dipping galvanized steel sheets.

PPGL STEEL COIL PARAMENTERS

Here comes several frequent-used PPGL steel coil products:

• Color coated roofing sheets
• Car steel sheets
• household electric appliances steel sheets

PPGL STEEL COIL DESCRIPTION

PPGL STEEL COIL APPLICATION

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).
