Crafted from premium black slate, this roof tile shows a deep charcoal-black tone with light-grey transitions for a calm, unified look. Its natural cleft matte surface preserves slate's characteristic foliated layering for a rustic, handcrafted feel. Each 20x30cm tile is shaped with a rounded fish-scale bottom; laid in a staggered, overlapping pattern, it forms a layered fish-scale texture full of dimension and rhythm. At a slim 0.5-0.7cm thickness, it lightens roof loads and installs flexibly. Waterproof, weather-resistant, frost-proof, durable, and fade-resistant, slate suits villa pitched roofs, pavilions, and feature facades. Its natural fish-scale overlap is rustic and elegant, an ideal decorative material for Chinese, neo-Chinese, and European architectural roofs.
