PPGL Coil
PPGL coil is based on aluminum-zinc alloy coated steel, combined with durable pre-painted finishes. Compared with PPGI, PPGL provides enhanced corrosion resistance and longer service life, especially in harsh environments such as coastal, industrial or high-humidity areas. It is widely used for high-end roofing, exterior cladding and long-life building systems where durability and weather resistance are critical.
