Core Advantages 

1. Lightweight & High Strength

   Only 1/6 the weight of cement tiles or clay tiles, it adds little load to buildings and is highly suitable for old house renovation.
2. Sound Insulation & Noise Reduction

   The sand layer cushions the impact of rainwater, eliminating the loud dripping noise common with plain metal roofs.
3. Weather & Corrosion Resistance

   Double protection of aluzinc steel substrate and mineral stone chips prevents rust in coastal salt fog and rainy regions, with a service life of over 50 years.
4. Heat Insulation & UV Resistance

   Matte granular surface reflects ultraviolet rays to cool indoor spaces and cut energy costs, while resisting color fading.
5. Wind & Waterproof Performance

   Interlocking overlapping structure withstands Grade 12 strong winds and prevents leakage under heavy rain.
6. Easy Installation

   Large single sheet size, cuttable and bendable, enabling fast dry installation on steep-slope roofs.
7. Fireproof & Eco-friendly

   Class A fire resistance, fully recyclable materials and zero formaldehyde pollution.
