Cold Rolled Spark Free Smooth Surface Galvanized Sheet Coil Used For PPGI

Cold Rolled Spark-free Smooth Surface Galvanised Steel Coil Used For PPGI

Description

According to the surface morphology of the coating:

Conventional zinc spangle: Formed naturally by the solidification of molten zinc, with a distinct crystalline pattern.

Small zinc spangle: Developed through special treatment to inhibit spangle growth, resulting in a more uniform surface.

Spark-free (smooth surface): Rolled on a finishing machine, resulting in a mirror-like smooth surface, ideal for color coating.

Alloyed galvanized sheet (GA): Surface is a uniform dark gray zinc-iron alloy layer.

According to substrate type:

Commercial grade (CQ): For general use.

Stamping grade (DQ): Used for general stamping.

Deep drawing grade (DDQ), extra-deep drawing grade (EDDQ), ultra-extra-deep drawing grade (SEDDQ): Used for complex parts with increasingly demanding formability requirements.

High-strength structural steel (HSLA), duplex steel (DP), etc.: Provides corrosion resistance while ensuring strength.

Based on coating weight (unit: g/m², total for both sides):

Common standards: Z60, Z80, Z120, Z180, Z275, etc. (The numbers represent the grams of coating per square meter). The higher the number, the thicker the coating, the stronger the corrosion resistance, and the higher the price.

ADVANTAGES:

Low processing cost: 
The cost of hot-dip galvanizing and rust prevention is lower than that of other paint coatings;

Multi-faceted protection: 
Each part of the plated parts can be plated with zinc, even in recesses, sharp corners and hidden places
 an be protected in many ways;

The inspection is simple and convenient: 
The hot-dip galvanized layer can be tested visually and with a simple non-destructive coating thickness table.
