RAL 9002 is a grayish white. This color is commonly used for pre-painted steel coils (PPGI/PPGL), and when combined with GI and GL steel substrates, it achieves an excellent balance of functionality, durability, and visual appeal.

Production Video
RAL 9002 is applied to the surfaces of galvanized steel coils and galvanized-aluminum steel coils to produce PPGI and PPGL coils. The entire process can be summarized as follows: substrate preparation → chemical pretreatment → precision coating → baking and curing.
RAL 9002 PPGI and RAL 9002 PPGL
Definitions of the Two
RAL 9002 PPGI Definition: The full name is RAL 9002 Pre-Painted Galvanized Steel. The substrate is cold-rolled steel sheet, coated with a layer of zinc (typically 30–275 g/m²), followed by degreasing and chemical conversion treatment. It is then spray-coated with RAL 9002-colored paint (typically PE/HDP/PVDF) and cured through baking.
RAL 9002 PPGL Definition: The full name is RAL 9002 Pre-Painted Galvalume Steel. The substrate is also cold-rolled steel sheet, but the surface coating is an aluminum-zinc alloy (approximately 55% aluminum and 43% zinc, with a coating weight of 30–150 g/m²). The subsequent coating process is identical to that of PPGI, making it suitable for highly corrosive environments.
Performance Comparison
Performance Indicators
RAL 9002 PPGI
RAL 9002 PPGL
Corrosion Resistance
Medium strength, suitable for indoor or light outdoor environments (such as factories in dry areas).
Excellent, resistant to corrosive environments such as humidity, coastal areas, and industrial exhaust gases.
Heat Resistance
Generally suitable, long-term operating temperature ≤120℃; prone to aging in high-temperature environments.
Excellent, long-term operating temperature ≤315℃, high heat reflectivity, suitable for outdoor high-temperature scenarios such as rooftops.
Processability
Good strength, easy to shear, bend, and stamp; suitable for complex shaping processes (such as appliance panels).
Good, toughness slightly better than PPGI, but care must be taken during processing to avoid damaging the coating; suitable for large building components.
Cost
Lower strength, price per ton is 10%-15% lower than PPGL.
Higher, due to the high cost of aluminum-zinc alloy coating.

RAL 9002 Color Steel Coil
RAL 9002 Matt Color-Coated Steel Coils
The matte finish enhances the visual and tactile experience of RAL 9002.
Reduces light pollution: The matte finish does not reflect light intensely, effectively reducing glare and creating a softer visual appearance.
Hides imperfections: Compared to glossy finishes, the matte coating better conceals minor scratches or unevenness on the substrate surface.
Excellent Weather Resistance: High-quality matte powder coatings offer superior weather resistance and color retention, ensuring that the RAL 9002 color remains stable even after years of outdoor exposure.
Versatile Design Compatibility: Suitable for a variety of design styles, including modern minimalist, industrial, and high-end commercial aesthetics. It can be paired with the glossy RAL 9002 or other color codes to create a sense of depth and dimension.
High Corrosion Resistance: Both RAL 9002 PPGI and RAL 9002 PPGL feature corrosion-resistant substrates; combined with the protective barrier provided by the paint coating, they offer even greater corrosion resistance.
Excellent Color Stability: Using high-quality coatings (PE/SMP/HDP/PVDF) combined with a rigorous baking process, RAL 9002 offers outstanding weather resistance, with no noticeable fading or discoloration for up to 10 years of outdoor use.
Clean and Consistent Appearance: The low-saturation tone of RAL 9002 effectively conceals minor surface imperfections while complementing modern minimalist design styles. It is widely used in applications such as industrial buildings, office buildings, and home appliance panels.
Easy Maintenance: The smooth surface coating is stain-resistant and easy to clean, eliminating the need for frequent sanding or touch-ups and reducing long-term maintenance costs.
