1. Prepainted Galvanized Steel Coil description:
Prepainted Galvanized Steel Coil is a process that involves coating metals such as steel and iron with a thin layer of zinc. Since the zinc interacts more readily with oxygen than iron or steel do, it will tend to corrode first and protect the underlying metal. Prepainted Galvanized Steel Coil is typically a multiple step process that requires a metal work piece to be fluxed in molten or aqueous zinc ammonium chloride before a layer of zinc is bonded to it. The pure zinc layer then turns into zinc oxide when it is exposed to oxygen, and finally zinc carbonate after exposure to carbon dioxide.

2. Prepainted Galvanized Steel Coil technical process
After cleaning and acid pickling, the steel coil is submerged in melted zinc, a chemical reaction permanently bonds the zinc. The zinc actually permanently becomes a part of it and the successive
Layers are a mixture of zinc and iron. Prepainted Galvanized Steel Coil is a special type of steel coil used
In a number of different applications within fabrication and manufacturing environments

4. Prepainted Galvanized Steel Coil main usage scope:
Prepainted Galvanized Steel Coil is widely used in home appliances, kitchen utensils, handicrafts, construction formwork, granary, revealed rain, chimneys, roof tile, fire shutter doors, construction
Industry, as raw material for the production of corrugated panels, fencing products, drywall
Panel profiles, ventilation systems etc.


5. Prepainted Galvanized Steel Coil advantages:

1) Low iron loss, high magnetic flux strength, comes up to the international advance standard
2) Slight thickness difference between the horizontal and the longitudinal direction, promising the high lamination factor
3) Processing Performance: Easily punched and cut, high dimensional accuracy
4) Insulating coating: Uniform color, good insulation, strong adhesively, high heat resistance, high imputrescibility
5) Smooth surface, no rust, no rolling marks, no cold lap, no crease, no bubble cell, no delaminating defects
