Tempered float glass is a type of safety glass that is widely used in construction and automotive industries. It is made by heating annealed float glass to a high temperature and then rapidly cooling it, resulting in a glass that is much stronger and more resistant to breakage than standard float glass.

Tempered glass is used for safety reasons because it is more resistant to impact, thermal stress, and wind pressure than regular glass. It is commonly used for windows, doors, shower enclosures, and other architectural applications where safety is a primary concern.

China is a major producer of tempered float glass, with a significant portion of the world’s tempered glass supply coming from Chinese manufacturers. This is due to China’s advanced manufacturing technologies, low labor costs, and abundant raw materials, which enable it to produce large quantities of tempered glass at a competitive price point.

In terms of production, tempered float glass is typically made by heating annealed float glass to around 600°C and then rapidly cooling it with air jets, which creates a surface compression that makes the glass more resistant to breaking. The resulting tempered glass is then cut and polished to the desired size and shape.

Overall, tempered float glass is a critical component in the construction and automotive industries, and China’s competitive production capabilities make it a key player in this global market.
