PPGI stands for “Pre-Painted Galvanized Iron,” which refers to steel coils that have been coated with a layer of paint or primer before being formed into various products. PPGI steel is commonly used in construction for roofing, siding, gutters, and other applications where corrosion resistance and aesthetic appeal are important.

PPGI gutter steel specifically refers to gutters made from pre-painted galvanized steel. Gutters are used in buildings to collect and divert rainwater away from the structure, preventing water damage to walls, foundations, and landscaping.
