Tempered glass and Heat Strengthened glass are glass products with strong and uniform compressive stress on the surface obtained by special heating and rapid cooling treatment of float glass.

The surface stress of tempered glass is as high as 90 MPa or more, which significantly increases the strength of tempered glass compared to ordinary glass, up to 4 to 5 times. In addition, tempered glass also has extremely high impact resistance and weather resistance, which can effectively resist external impacts and the influence of harsh environments. After being broken, tempered glass will form small obtuse angle particles like honeycomb shapes, which greatly reduces the risk of harm caused by glass fragments to the human body and ensures the safety of users.

The surface compressive stress of heat strengthened glass is between 24-69 MPa, and its mechanical strength is 1.6 to 2 times that of ordinary annealed glass, while its thermal stability is excellent. In terms of flatness and transparency, heat strengthened glass is closer to ordinary annealed glass, and at the same time, it’s without the risk of glass spontaneous breakage. When heat strengthened glass breaks, it will present large radial fragments, which may have sharp edges and hurt people.

Application: Tempered glass is widely used in multiple fields due to its excellent strength and safety. These fields include glass doors, building curtain walls, facade windows, indoor partitions, and furniture, among others. Additionally, they are often used near heat sources or in locations that may be subjected to severe thermal shocks.

Glass partition use tempered glass

We offer tempered glass of different thicknesses according to demand, such as 3mm, 4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 15mm, and 19mm. The maximum size can reach 3200mm × 17000mm, and there are also minimum sizes of 200mm × 300mm for you to choose from.

Heat strengthened glass is widely used in industries that require high thermal stability, such as glass curtain walls, greenhouses, and warm rooms. It overcomes the self explosion problem of tempered glass and is suitable as a structural material that requires durability and safety. The maximum thickness of semi tempered glass is 10mm. For thicknesses exceeding 10mm, we recommend using tempered glass.
