This decorative wall panel adopts a regular woven grid embossed structure formed by interlaced horizontal and vertical raised strips. Horizontal rib segments carry fine parallel shallow striations with uneven rough granular surfaces, intersecting vertically with slender vertical grooved strips to form repetitive square lattice units. Each raised woven band presents subtle uneven tactile undulations, with consistent staggered interweaving across the whole slab, combining neat geometric grid order with coarse hand-finished granular relief texture.
