Color Coated Steel Coil (PPGI and PPGL)

Color coated steel coil, known as PPGI and PPGL prepainted coil, adopts hot-dip galvanized or galvalume base metal with organic polymer paint coating. , it integrates anti-corrosion performance, decorative color and easy forming. We supply multi-paint, multi-color coated coils, support custom color, coating thickness and slitting service for construction, home appliance and architectural decoration industries.

Available Grades

  • PPGI Prepainted Galvanized Coil: Zinc-coated base color steel coil, cost mainstream grade, great inland anti-rust performance, the most popular material for ordinary factory roofing and wall cladding.
  • PPGL Prepainted Galvalume Coil: Al-Zn alloy substrate coated coil, 2-3 times longer service life than PPGI, excellent salt corrosion resistance for coastal and high-humidity outdoor projects.
  • PE Polyester Coated Coil: Standard economy paint grade, good color adhesion, easy bending processing, ideal for general indoor decoration and low-budget building projects.
  • HDP High Durability Polyester Coil: Weather-resistant upgraded paint, strong UV anti-fading ability, fit long-term outdoor exposed building exterior usage.
  • PVDF Fluorocarbon Coated Coil: Premium anti-aging grade, ultra anti-fading, acid and alkali resistant, customized for high-end facade and corrosive industrial plant exterior.

Product Features

  • Dual-layer Anti-corrosion Protection: Combined metal substrate + organic paint double protection, effectively isolate air, moisture and chemical medium to avoid steel rusting.
  • Rich Custom Color Matching: Support RAL standard color, customized matte/glossy finish, uniform surface color, no color difference for batch finished products.
  • Excellent Cold Forming Performance: Flexible integrated coating, no peeling or cracking during bending, stamping and profiling, adapt secondary profiling processing.
  • Strong Weather & UV Resistance: High-grade paint resists sunlight aging, rain erosion and temperature alternation, keep original color for 15-30 years outdoors.
  • Lightweight & High Structural Strength: Low unit weight reduces building load, stable base steel mechanical strength, easy transportation and on-site installation.
  • Fire-retardant & Easy Maintenance: Standard fireproof coating grade optional, smooth surface dust-proof, easy daily cleaning without extra anti-rust maintenance.

Applications

  • Industrial Building Envelope: Processed into roof panel, wall panel and corrugated sheet for factory, warehouse, logistics park outer enclosure construction.
  • Civil Prefab House Material: Sandwich panel surface material for temporary villa, container house, movable prefabricated building exterior decoration.
  • Home Appliance Shell: Interior coated steel for refrigerator, washing machine, air conditioner outer shell, beautiful surface and anti-scratch performance.
  • Architectural Exterior Decoration: High-end PVDF coated coil for commercial mall, office building facade, outdoor curtain wall decorative profiling board.
  • Agricultural & Breeding House: Anti-ammonia special coated coil for farm breeding barn, greenhouse outer plate, adapt peculiar corrosive gas environment.
  • Automotive & Container Parts: Light color coated steel for carriage outer board, logistics container side plate, lightweight anti-corrosion auxiliary parts.

Product Advantages (Customer Value)

  • Cut Long-term Maintenance Cost: Integrated factory painting eliminates later on-site painting work, save manual painting, anti-rust repair and renovation expense.
  • Short Project Construction Period: Finished colored coil can be directly profiled for installation, simplify construction procedure, greatly speed up building enclosure progress.
  • Improve Product Market Competitiveness: Uniform high-grade color improves finished panel appearance, help downstream processors raise product selling price and brand grade.
  • Adapt Complex Application Environment: Diversified substrate and paint grades match inland, coastal, chemical plant, breeding farm different corrosive working scenes.
  • Stable Batch Color Consistency: Automatic roller coating production, unified color formula, guarantee zero color difference for repeat order and batch project supply.

FAQ

  1. Q: What is the core difference between PPGI and PPGL coil?
    A: PPGI uses pure zinc galvanized base for inland common use; PPGL adopts aluminum-zinc substrate, owns 3 times longer anti-corrosion life, ideal for coastal salty environment.
  2. Q: How long is the outdoor service life of color coated coil?
    A: PE coating 8-12 years, HDP coating 15-20 years, PVDF fluorocarbon coating can reach 25-30 years outdoor anti-fading service life.
  3. Q: Can you customize non-standard RAL color?
    A: Yes, we support customized special color, matte/gloss surface finish, meet personalized architectural decoration design needs.
  4. Q: What width and inner diameter can you supply?
    A: Common width 600mm-1250mm, default inner diameter 508mm/610mm, support custom slitting any narrow width size.
