Cold Rolled Spark Free Smooth Surface Galvanized Sheet Coil Used For PPGI

Cold rolled spark-free smooth surface galvanized steel coil specifically designed for PPGI (Pre-Painted Galvanized Iron) applications, featuring mirror-like smooth surface finish ideal for color coating.

• Conventional Zinc Spangle: Natural solidification pattern with distinct crystalline appearance
• Small Zinc Spangle: Uniform surface achieved through special treatment to inhibit spangle growth
• Spark-free (Smooth Surface): Mirror-like finish produced by finishing machine rolling, perfect for color coating
• Alloyed Galvanized Sheet (GA): Uniform dark gray zinc-iron alloy layer surface

• Commercial Grade (CQ): Standard grade for general applications
• Stamping Grade (DQ): Suitable for general stamping operations
• Deep Drawing Grades: DDQ, EDDQ, SEDDQ for increasingly complex formability requirements
• High-Strength Grades: HSLA, DP (duplex steel) providing corrosion resistance with enhanced strength

Common coating weight standards (g/m² total for both sides): Z60, Z80, Z120, Z180, Z275. Higher numbers indicate thicker coatings, providing superior corrosion resistance.

• Low Processing Cost: Hot-dip galvanizing provides more economical rust protection compared to other coating methods
• Comprehensive Protection: Complete zinc coverage including recesses, sharp corners, and hidden areas
• Easy Inspection: Simple visual and non-destructive coating thickness testing methods

Customized packaging available according to customer requirements and factory standards.
