PPGI is the abbreviation of Pre-Painted Galvanized, that is, pre-painted galvanized steel. Usually refers to PPGI Coil (color-coated galvanized coil), PPGI Sheet (color-coated galvanized sheet) and other steel products. It is based on galvanized coils and then covered with color coatings to give the product more Color, and this rich and beautiful surface makes it more versatile in use.

PPGL is the abbreviation of Pre-Painted Galvalume, which is covered with a layer of color coating on the basis of galvalume coils.

Type of coating structure

2/1: Apply twice on the upper surface, once on the lower surface, and bake twice.

2/1M: Coat the upper and lower surfaces twice and bake once.

2/2: Coat the upper and lower surfaces twice, and bake twice.

Uses of different coating structures:

2/1: The corrosion resistance and scratch resistance of the single-layer back paint are poor, but it has good adhesion and is mainly used in sandwich panels;

2/1M: The back paint has good corrosion resistance, scratch resistance and processability, and has good adhesion. It is suitable for single-laminated panels and sandwich panels.

2/2: The corrosion resistance, scratch resistance and processing formability of the double-layer back paint are good, and most of them are used for single-layer laminates, but their adhesion is poor, so they are not suitable for sandwich panels.
