Product Description: Deep Processed Corrugated Prepainted Galvanized Steel Coil (PPGI)
Our deep processed corrugated prepainted galvanized steel coil (PPGI) is a high-performance building material engineered for precision roofing and wall cladding applications. Crafted from premium hot-dip galvanized steel substrate with a durable multi-layer organic coating, it undergoes advanced cold rolling and corrugation pressing to form standardized or custom-profile roof sheets, wall panels, and structural components.
Available in thicknesses from 0.12mm to 1.5mm and widths of 600–1250mm, our corrugated PPGI coils can be pressed into popular profiles such as trapezoidal, corrugated, and interlocking panels, tailored to meet specific structural and aesthetic requirements. The metallic coating (Z30–Z275g/m² or AZ60–AZ180g/m²) delivers exceptional corrosion resistance, while the 20–45μm total organic coating ensures long-lasting color fastness, weather resistance, and scratch protection, even in harsh outdoor environments.
Ideal for industrial warehouses, agricultural buildings, commercial roofing, and residential construction, our deep processed corrugated PPGI sheets offer excellent structural strength, lightweight installation, and easy maintenance. We support custom corrugation patterns, color matching (RAL/Pantone), and slitting/cutting services to fit precise project dimensions.
With strict quality inspection and standard export packaging, our corrugated PPGI products comply with international standards (ASTM A653, JIS G3302) and are ready for global delivery. Whether for large-scale construction projects or small-batch custom orders, our deep processed corrugated PPGI provides reliable performance, cost-effectiveness, and aesthetic appeal for roofing and cladding solutions worldwide.
