Anti-corrosion PPGL PPGI 275g/㎡ 180g/㎡ Prepainted Color Galvanized Steel Coils
PPGI Steel Coil Introduction
Color-coated coils are based on hot-dip galvanized sheet, hot-dip galvanized sheet, electro-galvanized sheet, etc. After surface pretreatment (chemical degreasing and chemical conversion treatment), one or several layers of organic coatings are applied on the surface, and then A product that has been cured by baking. It is also named after the color steel coils coated with organic coatings of various colors, referred to as color coated coils.
The color-coated steel strip using hot-dip galvanized steel strip as the base material is protected by the zinc layer, and the organic coating on the zinc layer plays a covering and protective role to prevent the steel strip from rusting, and the service life is longer than that of the galvanized strip. 1.5 times.

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, mainly
To be applied to 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 processability of the double-layer back paint are better, and most of them are used for single-layer paint.
Laminated board, but its poor adhesion, not suitable for sandwich panels.
Applications of PPGI Coils
Pre-painted galvanized steel combines utility with beauty. It consists of tin, chrome, zinc, or paint, which are the extra finish applied to the natural steel surface. The application of the coating is to protect the surface of steel from oxidation and it is also used to enhance requirements for visual appearance.
Color-coated coil is a method of roller coating on hot-rolled substrates, galvanized substrates, aluminum-zinc-plated substrates, cold-rolled substrates, tin-plated substrates, stainless steel substrates and other substrates after surface pretreatment (degreasing and chemical treatment). Coated with one or more layers of liquid paint, the obtained plate after baking and cooling is a coated steel plate, which is made into a color-coated coil, which is mainly used in building roofs, walls, steel structure workshops, home appliance boards, purification Clean workshop and other fields.
