China Heat Strengthened Glass
SERENE As a leading manufacturer of heat strengthened glass, we focus on production and R&D, providing customized solutions to meet specific customer needs.
what is Heat Strengthened Glass
Heat strengthened glass is also called semi tempered glass. Heat strengthened glass is a type between ordinary flat glass and tempered glass. It has some advantages of tempered glass, and its strength is higher than that of ordinary float glass, which is twice that of ordinary float glass. At the same time, it avoids the unsatisfactory weaknesses of tempered glass, such as poor flatness, easy self-explosion, and overall shattering once damaged.
types of Heat Strengthened Glass
Insulating glass can be made of 3, 4, 5, 6, 8, 10, 12mm thick original glass, and the air layer thickness can be 6, 9, 12mm.

Heat Strengthened Glass Specification
Semi-tempered glass has a wide range of sizes, with the maximum size reaching 2440mm×6000mm and the minimum size being 200mm×300mm.
The maximum size of flat tempered glass can reach 10000mm×3300mm, and the size range of bent steel is 2800mm×2200mm.
Thickness range: The thickness of semi-tempered glass is generally between 3-19mm.
Advantages of Heat Strengthened Glass
1. High strength: A compressive stress layer is formed on the surface of heat-treated glass, which significantly improves the overall strength of the glass. Heat-strengthened glass is not easy to break when subjected to external forces. The impact strength and bending strength are 3-5 times that of ordinary glass.
2. Impact resistance: Heat-strengthened glass has high impact resistance and can effectively resist the impact and extrusion of external forces. The heat resistance is 3-5 times that of ordinary glass, which makes heat-strengthened glass have a wide range of application prospects in the fields of automobiles, construction, etc.
3. High safety: When heat-strengthened glass is damaged by external forces, it will show a network of cracks, but it will not collapse and scatter immediately, but maintain the overall structure, thereby reducing the risk of injury to people and property.
Heat Strengthened Glass producing process
- Heating: Heating the glass to a temperature close to the softening point (usually over 620 degrees).
- Cooling: Rapidly cooling the heated glass so that the surface hardens while the interior remains softened, thereby forming compressive stress on the surface and tensile stress inside
Heat Strengthened Glass applications
1. Construction: Heat-strengthened glass is often used as building doors and windows, curtain walls, and partitions due to its high strength and safety. It not only improves the overall aesthetics of the building, but also effectively protects personnel safety.
2. Automobile: Heat-strengthened glass is widely used in the automotive industry, such as car windshields and side windows. It can effectively improve the driving safety of vehicles and reduce accidents caused by glass breakage.
3. Home appliance: Heat-strengthened glass is also widely used in home appliances. For example, the observation windows of home appliances such as ovens and microwave ovens are usually made of heat-strengthened glass to ensure the safety of users during use.

FAQ
Is heat strengthened glass a composite material?
Heat strengthened glass is not a typical composite material, but a single material that has undergone special heat treatment. The rapid cooling process improves the strength and thermal shock resistance of the glass.
Is heat strengthened glass semi-tempered glass?
Yes
Heat strengthened glass and semi-tempered glass are the same type of glass, also known as heat-strengthened glass. They are both types between ordinary flat glass and tempered glass, combining some of the advantages of tempered glass while avoiding some of the disadvantages of tempered glass
Is heat strengthened glass physically tempered?
No
Heat-strengthened glass is not physically tempered. Although both heat-strengthened glass and physically tempered glass are strengthened by heat treatment, they differ in processing, stress distribution and application scenarios.
Physical tempering is achieved by heating the glass to a point close to the softening point and then rapidly cooling it, usually by blowing air on both sides of the glass. This cooling method causes compressive stress to form on the surface of the glass and tensile stress to form inside.
How toxic is heat-strengthened glass?
Heat-strengthened glass (i.e. tempered glass) is non-toxic under normal use conditions and will not have a direct impact on human health. Tempered glass is made from ordinary glass that has been heat-treated and cooled. Its main components are oxides such as silicon dioxide and aluminum oxide. These components are stable under normal conditions and will not release harmful substances.
