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.
