China's Tempered Glass Industry BY QYResearch

Published Date: 2022-09-04
Tempered glass/Reinforced glass is safety glass. Tempered glass is actually a kind of prestressed glass. In order to improve the strength of the glass, chemical or physical methods are usually used to form compressive stress on the surface of the glass. When the glass is subjected to external force, the surface stress is first offset, thereby improving the bearing capacity and enhancing the resistance of the glass itself. Wind pressure, cold and heat, impact, etc. Pay attention to distinguish it from glass fiber reinforced plastic.

After tempering, uniform compressive stress is formed on the surface of the glass, while tensile stress is formed inside, which improves the bending and impact strength of the glass, and its strength is about four times that of ordinary annealed glass. The tempered glass that has been tempered cannot be cut, ground, etc. or damaged, otherwise it will be "shattered" due to the destruction of the uniform compressive stress balance.

In the context of accelerated urbanization, my country's construction industry has ushered in good development opportunities, and the demand for new composite functional materials has become increasingly prominent. In 2021, China's tempered glass output will be 620 million square meters, a year-on-year increase of 13.1%.

my country is one of the major glass manufacturing countries, and the export volume of tempered glass is greater than the import volume. In 2021, China's toughened glass exports will be 2.239 million tons, a year-on-year increase of 3.61%; China's toughened glass imports will be 107,000 tons, a year-on-year increase of 296.30%.


With the development of construction, automobile, decoration, furniture, information industry technology and other industries and the improvement of people's requirements for living space environment, functional processing products such as safety glass and energy-saving insulating glass have been widely used. The supply and demand pattern and consumption structure of flat glass are changing. The upgrading of residents' consumption structure, the encouragement of independent innovation of enterprises, the construction of new rural areas and the process of urbanization will ensure that the growth trend of the domestic market's medium and long-term demand for glass products will remain unchanged.

According to the data from the National Bureau of Statistics: China's tempered glass output in May 2022 was 50 million square meters, down 12.9% year-on-year; from January to May 2022, China's cumulative output of tempered glass was 220 million square meters, down 9.8%; 2016- In 2021, China's tempered glass production will increase year by year since 2018, and will reach the highest in 2021.

Tempered glass is widely used in high-rise building doors and windows, glass curtain walls, indoor partition walls, furniture, sightseeing elevator passages, etc. In recent years, there has been an overproduction of low-end steel cover glass. According to the company's data, in the first half of 2020, more than 400 steel and glass-related enterprises were newly registered, a year-on-year decrease of 22.66%.

In 2021, the export volume of tempered safety glass for vehicles in China is 129,273 tons, an increase of 27.21% year-on-year; the import volume of tempered safety glass for vehicles in China is 919.4 tons, an increase of 5.42% year-on-year. In 2021, the export volume of tempered safety glass for vehicles in China is 129,273 tons, an increase of 27.21% year-on-year; the import volume of tempered safety glass for vehicles in China is 919.4 tons, an increase of 5.42% year-on-year.

According to the data, in the first half of 2022, China's tempered glass export volume was 73,900 tons, and the export value was 166 million US dollars. From January to June 2022, the national cumulative output of tempered glass was 270.216 million square meters, a decrease of 23.983 million square meters compared with the same period of the previous year, and the cumulative output decreased by 9.7% year-on-year; the average monthly output was 45.036 million square meters.

In terms of "guiding the healthy development of the green building materials industry and promoting the transformation and upgrading of the building materials industry", the Ministry of Industry and Information Technology and the Ministry of Housing and Urban-Rural Development have selected glass as a green building material due to the large share of glass in green building materials, obvious results, and high industry maturity. The first variety of building materials standard work, tempered glass will develop into a green industry in the future.
