Skin Pass Zinc-Coated Galvanized Steel refers to hot-dip galvanized steel coil/sheet that has undergone a “skin pass” (temer rolling) process. This treatment enhances the surface smoothness, flatness, and stamping/formability while preserving the excellent corrosion resistance of the zinc coating. It is the preferred base corrosion-resistant material for industries requiring complex processing or high surface quality, such as automotive panels, high-end home appliance casings, and complex stamped parts.
Skin Pass Zinc-Coated Galvanized Steel Products
Wanzhi Group supplies Skin Pass Zinc-Coated Galvanized Steel, encompassing a full range of base materials including coils, sheets/plates, and strips. Specifications can be customized according to requirements, suitable for various high-end processing scenarios, and compliant with international standards such as JIS G3302, ASTM A653, EN 10346, and GB/T 2518.
- Skin Pass GI Coil: Undergoes continuous skin pass processing, resulting in a uniformly smooth surface. It can be used directly as raw material for continuous stamping and roll forming, and is convenient for storage and transportation.
- Skin Pass GI Sheet/Plate: Produced from GI Coil through skin passing, leveling, and cutting. It features regular dimensions, flat shape, no wave edges, and no warping, suitable for direct processing of appearance parts.
- Skin Pass GI Strip: Produced from GI Coil through precision slitting combined with skin pass processing. It has smooth edges, precise dimensions, and a fine surface, often used as raw material for complex deep drawing processes like stamping and bending.
Advantages of Skin Pass Zinc-Coated Galvanized Steel
Skin Pass Zinc-Coated Galvanized Steel possesses excellent surface quality, superior formability, excellent shape flatness, and a reliable corrosion-resistant foundation.
- Smooth and Uniform: The skin pass roll imparts a uniform matte finish or specific roughness to the galvanized steel surface, resulting in high surface flatness and even gloss.
- Easy to Coat/Paint: The surface treatment enhances the adhesion of subsequent painting, coil coating, or film lamination, ensuring a smooth and flawless final paint finish.
- Excellent Mechanical Properties: The skin pass process optimizes the material’s internal structure, lowers the yield point, and improves the steel’s elongation and plasticity.
- Stable Corrosion Resistance: The skin pass treatment does not damage the zinc coating, so its corrosion and rust resistance are not compromised.
- No Wave Edges: The skin pass process relieves internal stresses, eliminating shape defects such as edge waves or center buckles that may occur during galvanizing.
- High Precision: Shape, dimensions, thickness, and width tolerances are precisely controlled, providing a stable and reliable dimensional guarantee for subsequent processing.
- Premium Surface Finish: Compared to standard galvanized steel, skin-passed galvanized steel offers a superior, non-rough surface texture suitable for high-end applications.
