Superior Surface Finish Surface Electro Galvanized Steel Coil EG Material
Electro galvanized (EG) steel coil refers to cold-rolled steel that has been coated with a layer of
zinc through an electrochemical process. This process allows for precise control
over the coating thickness and produces a very smooth, uniform surface.
3 Kinds Different Product Surface
1 Zero Spangle: smooth and uniform, without visible zinc patterns.
2 Electro-galvanize: smooth, bright, and uniform, with a fine metallic luster and no visible spangles.
3 Regular Spangle: visible zinc crystal patterns with a slightly textured metallic appearance.
distinct, visible zinc crystal patterns with a textured metallic appearance.

Quality Control
Our company introduced testing equipment,for product testing,raw materials,semi-finished products,
finished products.
a) Dimensional and Surface Measurement
thickness, width, length, zinc coating quantity,paint adhesion,surface roughness etc.
b) Mechanical Properties Testing
Room-temperature and high-temperature mechanical tests, Brinell hardness, HRC hardness,
micro-hardness, expansion, flattening, cupping, bending, compression.
C) Metallurgical & Corrosion Resistance
Macrostructure analysis, fracture detection, density, grain size, residual stress,
dezincification corrosion, salt spray, annealing.
Ocean Shipping
There are two ways to reinforce color coated steel coils: standard reinforcement and special
reinforcement.
standard reinforcement :
We protect the coils by adding cushioning materials and tightening them with lashing straps,
non-slip wooden blocks underneath to prevent movement, meanwhile, we use waterproof
package,and add desiccants to prevent against moisture.
Special Reinforcement
Based on standard reinforcement, we made impact-resistant frames to provide stronger
protection against impact, suitable for long-distance sea freight or harsh conditions.
Key Advantages
Superior Surface Finish: Provides a smooth, consistent, and aesthetically pleasing surface
that is perfect for subsequent finishing processes like painting or chromating.
Excellent Paint Adhesion: The clean, uniform surface ensures strong adhesion for paint and
organic coatings, preventing peeling or blistering.
Precise Coating Control: The electroplating process allows for exact and differential coating
weights on each surface.
