Classification by Manufacturing Process
Physically Tempered Glass: Made from standard soda-lime-silicate glass; it is heated to approximately 600°C and then rapidly cooled with high-speed air. It is the most widely used type in construction due to its low cost and high production capacity.
Chemically Tempered Glass: Also made from silicate glass, but utilizes an ion-exchange process to create compressive stress on the surface. It is suitable for thin glass (2–4 mm), offers high flatness with no significant warping, and is commonly used in electronic products and precision instruments.
Classification by Appearance and Light Transmission
Transparent Tempered Glass: The most basic type; it features high light transmission and is commonly used for standard doors, windows, and partitions.
Ultra-Clear Tempered Glass: Made from low-iron silicate glass, it has nearly colorless edges, superior light transmission, and excellent color fidelity; it is often used for high-end display cabinets and architectural features.
Tinted Tempered Glass: Produced by adding coloring agents during manufacturing (common colors include gray, bronze, and blue); it offers both decorative appeal and shading capabilities.
