Prime PPGI Color Coated Steel Sheet - Mill Supplier
Prime quality PPGI color coated steel sheet stands as one of the most versatile and performance-driven materials in modern construction and manufacturing industries. PPGI — Pre-Painted Galvanized Iron — combines a hot-dip galvanized or galvalume substrate with a factory-applied polymer coating system, delivering outstanding anti-corrosion properties alongside a broad spectrum of aesthetic options. From roofing panels and wall cladding to household appliances and automotive components, this material finds extensive application in environments that demand both structural integrity and visual appeal. As a mill-direct supplier, we offer certified prime-grade PPGI sheets with zinc coating weights ranging from Z60 to Z275 g/m², paint film thicknesses from 5 µm to 25 µm, and a full RAL/Pantone color palette. Our products comply with ASTM A755, EN 10169, and JIS G3312 standards, ensuring consistent quality across every coil and sheet we dispatch to global markets.
What is Prime Quality PPGI Color Coated Steel Sheet?
Prime quality PPGI color coated steel sheet is a cold-rolled, hot-dip galvanized steel substrate that undergoes a continuous coil coating process, applying primer and topcoat layers to both surfaces before forming. The result is a corrosion-resistant, UV-stable panel with a yield strength typically ranging from 280 MPa to 550 MPa, a base metal thickness of 0.13 mm to 1.5 mm, and coil widths up to 1,500 mm. It serves critical roles in roofing, façade systems, garage doors, and light-gauge steel framing.
Prime Quality PPGI Color Coated Steel Sheet Manufacturing Process
Production begins with prime cold-rolled galvanized coils entering a continuous coating line at speeds up to 180 m/min. The strip is chemically cleaned, passivated, and pre-treated with a chromate-free conversion layer before a roller-applied polyester, SMP, or PVDF primer is cured in a thermal oven at 230°C–260°C. A topcoat — typically 15 µm to 25 µm dry film thickness — is then applied, followed by a back coat of 5 µm to 12 µm, ensuring balanced performance on both faces. Finished coils are tension-leveled and slit to customer specifications.
Prime Quality PPGI Color Coated Steel Sheet Technical Specifications
Our PPGI color coated steel sheet is produced to the following verified parameters: base metal thickness 0.13 mm–1.5 mm (±0.02 mm tolerance); coil width 600 mm–1,500 mm; zinc coating Z60–Z275 g/m² per ASTM A653; topcoat dry film thickness 15–25 µm; pencil hardness ≥ 2H; T-bend flexibility T1–T2; 60° gloss value 30–85 GU; salt spray resistance ≥ 1,000 hours per ASTM B117; and tensile strength 280–550 MPa depending on grade. Available coatings include standard polyester (PE), high-durability silicon-modified polyester (SMP), and premium PVDF for extreme-weather applications.
