  • Enhanced Surface Protection – The fingerprint-resistant galvanized steel plate provides an additional protective coating that effectively prevents fingerprints, sweat, and corrosion, maintaining a clean and glossy appearance.

  • Versatile Application Options – Available in multiple types such as fingerprint-resistant, phosphated, and passivated plates, offering flexibility to meet different industrial and aesthetic requirements.

  • Improved Corrosion and Wear Resistance – Phosphating and passivation treatments strengthen surface durability, enhancing resistance to oxidation, rust, and environmental factors.

  • Excellent Processing Performance – Both ordinary and fingerprint-resistant galvanized steel plates feature stable mechanical properties and good formability, making them ideal for use in components that require no further surface treatment.

Product Description

Galvanized sheet refers to a steel plate coated with a layer of zinc on its surface. Galvanizing is one of the most economical and effective methods for preventing corrosion, with approximately half of the world’s zinc production used for this purpose. The primary function of galvanizing is to protect the steel plate’s surface from rust and extend its service life by applying a layer of zinc coating, resulting in what is known as a galvanized steel plate.

Plating Definition

(1) Normal Spangle Coating
In the natural solidification process of the zinc layer, zinc crystals grow freely, forming a coating with a distinct spangled pattern.

(2) Small Spangle Coating
During the zinc layer’s solidification, the growth of zinc crystals is artificially controlled to produce the smallest possible spangle structure.

(3) Zero Spangle Coating
By adjusting the chemical composition of the plating solution, a coating without visible spangle patterns is obtained, resulting in a smooth and uniform surface appearance.

(4) Zinc-Iron Alloy Coating
After the steel strip passes through the galvanizing bath, it is heat-treated to form a zinc-iron alloy layer throughout the coating. This type of coating appears dark gray with no metallic luster and can be directly painted after simple cleaning, without additional treatment.

(5) Differential Coating
This process applies different zinc layer weights to each side of the galvanized steel sheet according to specific application requirements.

(6) Skin Pass (Smoothing)
A light cold-rolling process performed on galvanized steel sheets to:

  • Improve surface appearance or coating adhesion;

  • Prevent slip lines (Lüders lines) or creases during subsequent processing;

  • Temporarily minimize surface irregularities.
