Z80 RAL9016 24 Gauge PPGI Steel Coil with Regular Spangle for Roofing and Wall Panel Applications

１．Product Overview

Z80 RAL9016 24 Gauge PPGI Steel Coil is a pre painted color coated steel coil used for roofing sheets, wall panels, building components, and general metal fabrication. The product combines galvanized or galvalume steel substrate with color coating to provide corrosion resistance, decorative appearance, and processing performance.

The RAL9016 color provides a clean white surface appearance for architectural and industrial panel applications. Regular spangle substrate supports a typical galvanized surface structure under the pre-painted coating system.

２．Technical Solution

The product uses galvanized steel coil or galvalume steel coil as the base material. The metallic coating provides corrosion protection, while the color coating improves surface appearance and weather resistance.

The color coating structure includes a 5–20μm top coating and a 5–10μm back coating, or adjusted according to client requirements. Surface treatments such as chromating, oiling, bright finishing, and fingerprint resistance can be selected based on storage, forming, and appearance requirements.

ASTM, GB, JIS, and DIN standards support different market and project requirements.
