Square paving tiles are a type of wear-resistant tile. They are mainly used in public places with high foot traffic, such as recreational plazas, municipal engineering projects, landscaping areas, roof gardens, garden balconies, shopping malls and supermarkets, schools and hospitals, and car 4S dealerships. The tiles feature simple colors, small surface dimensions, and often a textured or raised/relief pattern. They offer the advantages of slip resistance, wear resistance, and ease of repair.
