Prepainted Metal Package details

SGCC is a hot-dip galvanized cold-rolled steel sheet. Superior Corrosion Resistance The zinc coating thickness can reach 50–100 microns. An alloy layer forms between the coating and the steel substrate, ensuring strong adhesion; combined with the mechanism of electrochemical sacrificial protection, this provides long-term rust prevention. Anti-corrosion performance typically lasts 30–50 years, making it ideal for long-term outdoor exposure. Cost-Effective and Reliable Supply It utilizes SPCC cold-rolled steel—a low-cost material with mature processing characteristics—as its base. With a well-established production process and abundant market supply, it requires minimal maintenance over time, making it the most economical choice for long-term anti-corrosion applications. Excellent Workability It inherits the workability of SPCC cold-rolled steel, offering good ductility and plasticity. It is suitable for standard forming processes such as bending and pressing, and supports spot welding for easy assembly, meeting the requirements of most engineering projects. Outstanding Coating Adhesion The dense surface alloy coating adheres strongly and resists impact and abrasion. Subsequent paint coatings bond securely without peeling, allowing for enhanced aesthetics and durability.
