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.

Our Factory

to our products and customers by supplying the best quality product.

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.
