UV-Resistant Stone Tiles

UV-resistant stone tiles utilize ceramic-coated basalt granules with UV-absorbing additives, achieving ΔE≤3 color shift after 10,000 hours of accelerated weathering (ISO 4892-3) – critical for equatorial regions like Indonesia and Saudi Arabia. The 0.45mm AZ150 steel base is pre-treated with chromate-free passivation layer, reflecting 92% of UV radiation to prevent binder degradation. Combined with acrylic resin containing HALS (Hindered Amine Light Stabilizers), tiles maintain color integrity for 50 years under 2000W/m² solar exposure, outperforming traditional clay tiles by 300% in fade resistance. Hail impact resistance passes UL 2218 Class 4 standard (25mm ice ball at 140km/h), while the hydrophobic surface reduces dust adhesion by 70% in arid zones.

Installation integrates reflective underlayment (SRI≥85) to lower attic temperatures by 12°C, cutting AC costs by 25% in tropical warehouses. Our factory employs spectral matching technology to replicate historic building hues (e.g., Moroccan terracotta) with RAL color archives. Projects include Dubai’s Palm Jumeirah villas and Australian outback resorts, where tiles endured UV index 11+ for 8 years with zero fading.
