Architectural Glazed Products Testing

Glazed tiles are made from high-quality mineral raw materials through processes including crushing and screening, high-pressure forming, and high-temperature firing. They exhibit significant advantages such as high strength, good flatness, low water absorption, high flexural resistance, freeze-thaw resistance, acid and alkali resistance, and color permanence. Widely used in industrial and civil buildings such as factories, residences, hotels, and villas, glazed tiles are highly regarded by architects for their diverse shapes, simple yet colorful glazes, environmental friendliness, and durability.
