Ensure product quality and transportation
RAL 7030 (Stone Grey) is a commonly used color in the RAL color system. When used on PPGI (pre-coated galvanized steel coil), it produces a soft, matte grey finish, suitable for both consumer products and industrial panels. Our RAL 7030 color steel coil customers are mainly from the home appliance and construction industries.
This color is highly practical for the home appliance industry: it resists fingerprints, is not glaring under kitchen lighting, and pairs well with various trim pieces and seals. It belongs to the same material system as color-coated steel (PCM steel) used in home appliances.

Applications
This gray PPGI coating is highly durable. It is most commonly used on home appliances and also covers many building and electrical panels.
- Home Appliance Industry: Washing machines, dryers, dishwashers, refrigerators/freezers, water heaters, and small kitchen appliances.
- Electrical Equipment: Electric meter boxes, distribution panels, control cabinets, etc.
- Construction Industry: Roofing panels, wall panels, shelving, partitions, etc.


RAL 7030 Advantages
- Dual Protection and Corrosion Resistance: The zinc coating protects the base material, while the surface paint film provides an additional barrier; this dual-layer protection ensures excellent corrosion resistance.
- Good Formability: By selecting base materials of different grades (DX52D, SGCC), the formability of PPGI can be enhanced, ensuring that paint does not peel off on curved corners of home appliances or embossed door panels.
- Fingerprint-Resistant and Anti-Glare: The “stone gray” finish is more stain-resistant than white or glossy black, and its controlled gloss reduces glare under workshop and kitchen lighting.
