Double charge tiles are a type of ceramic tile that is made using a special manufacturing process. They are produced by pressing two layers of different colored clay together under high pressure, resulting in a tile with a double-layered design. The top layer is thicker than a typical glazed ceramic tile, giving it greater strength and durability.

Double charge tiles are often used in high-traffic commercial areas, such as shopping malls, airports, and hotels, due to their strength, durability, and resistance to wear and tear. They are also a popular choice for residential flooring and walls, as they offer a more luxurious and sophisticated look than standard ceramic tiles.
