RAL Colour and Surface Options for Aluminium Aluminium Systems.

RAL Classic Colour Range\n\nThe RAL Classic colour system provides over 200 standardised colours for powder-coated aluminium. Popular architectural colours include RAL 7016 Anthracite Grey (the most specified colour for modern aluminium systems), RAL 9005 Jet Black, RAL 9016 Traffic White, and RAL 8017 Chocolate Brown. QUALICOAT-certified powder coating ensures minimum 60-micron coating thickness and guarantees colour stability for the rated exposure period. All PONARC systems are available in any RAL Classic colour with standard 3-4 week lead time.\n\n## Anodised Finish Options\n\nAnodising produces distinctive metallic finishes that cannot be replicated by powder coating. Standard anodised colours include natural silver (C0), light bronze (C31), medium bronze (C32), dark bronze (C33), and black (C35). QUALANOD Class AA20 certification ensures minimum 20-micron oxide layer thickness suitable for external architectural applications. The anodised surface provides superior scratch resistance compared to powder coating.\n\n## Wood-Effect Sublimation Finishes\n\nSublimation technology transfers photographic wood-grain patterns onto pre-coated aluminium surfaces. The resulting finish is virtually indistinguishable from natural timber at conversational distance. Available patterns include European Oak, American Walnut, Siberian Larch, and Italian Stone Pine. The sublimated finish retains full aluminium durability with zero wood maintenance requirements.\n\n## Custom and Special Finishes\n\nCustom colour matching services can replicate any physical colour sample within Delta E 1.0 accuracy. Bi-colour configurations with different colours on internal and external faces accommodate varied architectural requirements. Metallic and pearlescent effects add premium visual quality for high-end residential installations. Textured finishes including fine sand, medium texture, and coarse grain provide tactile variation and improved fingerprint resistance.
