ASTM A879 2x1219mm Electrogalvanized Steel Coil Automobile Field Application
Electrogalvanized steel's combination of formability, surface quality, and corrosion resistance
makes it ideal for products where appearance and precise fabrication are critical.
3 Kinds Different Galvanized Steel Product
a) Zero Spangle: smooth and uniform, without visible zinc patterns.
b) Electro-galvanize: smooth, bright, and uniform, with a fine metallic luster and no visible spangles.
c) Regular Spangle: visible zinc crystal patterns with a slightly textured metallic appearance.
Our Factory
1) Company philosophy : “Making friends sincerely and developing with reputation” The quality

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.
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
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.
Primary Applications
♦ Electrogalvanized steel's combination of formability, surface quality, and corrosion resistance makes
it ideal for products where appearance and precise fabrication are critical.
♦ Automotive Industry: Interior panels, body parts that require excellent paintability, and various brackets
and components.
