In the world's tile industry, products with durability, safety and design flexibility are popular. Our matte light grey indoor-outdoor porcelain tile is a top choice for home and commercial projects. It has the classic look of concrete. It also has the practical benefits of high-quality porcelain. Let's explain the key industry facts about this versatile product.

Core Material & Basic Specifications

This tile is made of full-body porcelain. It is not cheap glazed ceramic. Full-body porcelain means the color and texture go through the entire tile. It is not just on the surface. It is 10mm thick. This thickness gives it strength for heavy use. The standard size is 24"x48" (a 2:1 ratio). This is a popular large format in modern tile design. It comes in three neutral colors: dark grey (anthracite), pure grey (concrete look), and sandy (beige-grey mix). The surface has a true matte finish. It does not reflect light. It has no fake "satin" coating. This finish looks sleek. It also serves practical purposes for safety and maintenance.
