ASTM SGCC Large Medium Small Grain Wrinkle PPGI Prepainted Galvanized Steel Coil

Premium Matt Wrinkle Texture: Features an elegant, low-gloss suede finish that effectively eliminates light glare and reflective pollution on building facades.

Enhanced Scratch & Wear Resistance: Micro-textured coating structure provides superior surface hardness, minimizing abrasion during roll forming and transport.

High Weathering Coating Protection: Formulated with advanced PE/PVDF paint systems for excellent UV resistance, preventing chalking and color fading over time.

Galvanized Corrosion Barrier: Hot-dip galvanized base coil (Z40-Z275) delivers dual protection against edge creep, atmospheric rust, and moisture.

Superior Cold Roll Forming Ductility: Flexible paint formulation maintains strong inter-coat adhesion during sharp 90-degree bending and profiling without micro-cracking.

Versatile RAL Color Customization: Available in full RAL color spectrums with controlled wrinkle grain size to match distinct architectural design demands.

Strict Thickness & Paint Film Control: Precise top coat (20-25um) and back coat (7-10um) application ensure consistent quality and extended service life.

Ideal for Premium Roofing & Cladding: Widely used for high-end residential roofing, villa siding panels, sandwich panels, and architectural wall systems.

ASTM & EN Standard Compliance: Fully certified to ASTM A755 and EN 10169 specifications, supplied with complete MTC 3.1 material quality certificates.

Heavy-Duty Ocean Export Packaging: Reinforced with eye-to-sky/eye-to-side steel strapping, plastic inner lining, and moisture-proof outer paper for ocean shipping.
