Zinc Coated Ral Hot Dipped Galvanized Coil Regular Spangle Little Spangle

Zinc Coated Hot Dipped Ral Galvanized Coil Regular Spangle Little Spangle 

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.
