Production Process
Cold rolled steel coil → degreasing → pickling → galvanizing → passivation → primer coating → top coating → curing → cooling → testing → winding and packaging
- Raw material for cold rolled steel coils: we have stock in our factory.
- Hot-dip galvanizing: Continuous hot-dip galvanizing process, according to the demand of the steel surface coated with a uniform layer of zinc (zinc layer thickness z30-350g / m²).
- Pre-treatment: Chemical conversion treatment
- Coating process: Apply a primer and a topcoat on the passivated hot-dip galvanized steel surface using a roller coating process.
- Baking, curing, and cooling: The coating is cured on the galvanized steel surface in a curing oven and then cooled.
- Quality Inspection: PPGI is produced in rolls and randomly selected PPGI coils are tested for coating thickness, adhesion, color difference, and salt spray resistance.

Prepainted Galvanized Steel Coil Advantages and Applications
Prepainted galvanized steel coil has excellent corrosion resistance, decorative properties, durability, and lightweight, and is an ideal material for construction, home appliances, automotive, agriculture, education, and other applications.

Corrosion Resistance | Galvanized (30-275g/m²) + Organic Coating (Polyester/Fluorocarbon), Salt Spray Life 500-3000 hrs (ASTM B117) | Roofing/Wall panels for buildings (Coastal, Industrial), Automotive (Fuel Tanks, Chassis Protection), Agricultural facilities (Greenhouses, Farms) |
---|---|---|
Decorative | Support RAL/Pantone full-color system, surface can be customized with wood grain, stone grain, and other textures (ΔE ≤ 1.5) | Appliance panels (refrigerators, air conditioners), commercial building curtain walls, interior decorative panels (light luxury style) |
Lightweight | Base material thickness 0.12-1.5mm, 70% lighter than concrete, reducing transportation and installation costs | Temporary buildings (sheds, showrooms), logistics containers, solar panel racking |
Economical | Low full cycle cost: initial price 600-900 USD/ton, maintenance cycle 10–15 years (no frequent painting) | Large industrial plants, low-cost housing projects, infrastructure (noise barriers, bus stops) |
Processing convenience | Direct stamping, bending, welding, compatible with automated production lines (yield rate ≥ 98%) | Ventilation ducts, cable bridges, machinery, and equipment shells (agricultural machinery, construction machinery) |
Environmental friendliness | Chrome-free passivation process, VOC emission ≤50g/L, steel recycling rate ≥95% (in line with LEED standards) | Green buildings (zero-carbon parks), medical facilities (antimicrobial coatings), food factories (easy-to-clean surfaces) |
