Comprehensive Guide to Galvanized Color Coated Embossed Steel Sheet

I. Product Definition

II. Core Production Process

1. Substrate Preparation: Select cold-rolled or hot-rolled steel sheet as the raw material, then conduct cutting, leveling and impurity removal on the surface.
2. Hot-dip Galvanizing: Immerse the substrate into molten zinc solution to form a uniform and dense zinc layer, which isolates air and moisture to achieve basic rust prevention.
3. Surface Pre-treatment: Perform degreasing, phosphating and passivation on the galvanized sheet to enhance the adhesion between the coating and the substrate, preventing coating peeling.
4. Color Coating Application: Adopt roll coating or spray coating technology to apply primer and topcoat on the substrate surface. Customized colors are available, and the coating features excellent weather resistance and acid-alkali resistance.
5. Embossing Forming: Use dedicated embossing molds to roll the steel sheet after coating curing, creating embossed surfaces with various patterns (such as rhombus, lentil and circle) to improve anti-slip performance.
6. Post-treatment & Inspection: Conduct drying, cooling, slitting and film laminating on the finished products. Test key indicators including coating thickness, adhesion and embossing definition to ensure compliance with quality standards.

III. Advantages and Disadvantages Analysis

(I) Advantages

1. Dual Anti-corrosion Protection & Long Service Life: The combined protection of zinc layer and color coating improves corrosion resistance by over 30% compared with ordinary galvanized sheets, suitable for harsh environments such as high humidity, coastal salt spray and industrial acid-alkali exposure.
2. Anti-slip, Wear-resistant & High Safety: The concave-convex embossed surface increases friction coefficient, preventing slipping during walking or cargo stacking. Meanwhile, the embossed structure disperses external impact, enhancing surface wear resistance.
3. Aesthetically Pleasing & Highly Decorative: Supports customization of various colors and embossed patterns, and can be directly used as exposed decorative surfaces without additional painting, reducing subsequent construction costs.
4. Excellent Processability & Wide Adaptability: Can be subjected to bending, cutting, stamping and welding processes without coating cracking or peeling, meeting processing requirements of building envelopes, home appliance casings and other scenarios.
5. Cost-effective & Eco-friendly: More affordable than stainless steel sheets, 100% recyclable and free of heavy metals in the coating, complying with environmental protection standards.

(II) Disadvantages

1. Coating Wear Susceptibility on Embossed Areas: The coating on raised embossed parts is more prone to wear and substrate exposure under long-term friction or impact compared with flat areas.
2. Limited Processing Precision: Complex embossed patterns may affect high-precision stamping forming, requiring additional mold adjustments for some precision processing.
3. Moderate High-temperature Resistance: The temperature resistance range of conventional color coatings is -50℃ ~ 120℃; exceeding 150℃ may cause coating discoloration and aging.
