RUNYING Steel Group is a leading manufacturer and direct supplier of Pre-Painted Galvanized Steel Coils (PPGI) and Pre-Painted Galvalume Steel Coils (PPGL). Engineered with a multi-layer baked coating system (primer, topcoat, and backing) over high-grade GI or GL substrates, our color-coated steel coils offer 15 to 30+ years of maintenance-free service life.

Compliant with global standards (EN 10169, ASTM A755, JIS G3312), our PPGI/PPGL coils eliminate the need for onsite painting and are widely used for architectural metal roofing, sandwich panels, cold storage, and home appliance manufacturing.
