Overview
The RAL Color Card PPGI Color Coated Corrugated Roofing Sheet merges structural robustness with design flexibility, featuring a corrugated profile and precise RAL color matching. Constructed from pre-painted galvanized steel (PPGI), this sheet combines the protective benefits of a zinc-rich coating with the aesthetic versatility of the RAL color system, offering over 200 standardized shades for seamless integration with building exteriors.
The classic corrugated design enhances load-bearing capacity and water drainage, while the polyester or PVDF topcoat ensures long-lasting color retention. Available in standard wave profiles (e.g., 31-1000, 25-900) and customizable lengths, it caters to both traditional pitched roofs and modern architectural designs, providing a balance of functionality and visual appeal.
Features
Architectural Color Precision: Leverages the RAL color card system to achieve exact color specifications, enabling architects to match historical building palettes or create bold contemporary statements.
Enhanced Weather Performance: The PPGI substrate with 20-25μm coating thickness resists rust in humid climates, UV degradation in tropical zones, and thermal shock in regions with extreme temperature fluctuations.
Structural Efficiency: Corrugated waves increase rigidity, allowing spans up to 3 meters without additional purlins, reducing framework costs while supporting snow loads up to 250 kg/m².
Installation Flexibility: Lightweight design (6-12 kg/m²) and interlocking profiles enable fast installation with standard roofing tools, compatible with wooden, steel, or concrete structures.
Low Maintenance Finish: The smooth, anti-static coating repels dust and prevents mold growth, requiring only annual rinsing to maintain appearance—ideal for hard-to-access roofs.
Application
Residential Architecture: Ideal for single-family homes, cottages, and townhouses, where color consistency enhances neighborhood aesthetics and curb appeal.
Commercial & Public Buildings: Used in schools, museums, and office parks to create iconic roofscapes, with RAL colors facilitating brand alignment or compliance with local building codes.
Industrial Roofing: Provides durable protection for factories and warehouses, with darker RAL shades (e.g., RAL 7016 Anthracite) hiding dirt in polluted environments while maintaining heat absorption control.
Heritage Restoration: Matches historical metal roofing colors for heritage buildings, combining modern corrosion resistance with authentic visual replication.
FAQ
Q: Can I get a physical RAL color sample before ordering?
A: Yes, we provide free color swatches (100x100mm) with actual coating finish for accurate on-site color evaluation.
Q: How does PVDF coating differ from polyester?
A: PVDF (Kynar 500) offers 50% longer color retention (20+ years) and better resistance to chemical pollution, suitable for coastal or industrial areas; polyester is cost-effective for mild climates.
Q: Are these sheets suitable for green roofs?
A: Yes, the corrugated profile supports lightweight vegetation systems when paired with waterproof underlayment, with RAL colors complementing rooftop gardens.
Q: What warranty covers color fading?
A: Polyester coatings carry a 10-year warranty, PVDF a 20-year warranty, guaranteeing ΔE ≤3 color difference under standard exposure conditions.
