Building Glass Market Analysis

It is reported that in 2003, the new building area was 1.8 billion m2, from which the estimated window glass usage area was about 360 million m2. In addition, the flat glass output was extrapolated.

In addition to flat glass, the Chinese architectural glass market has historically been difficult to count, especially for deep processing glass, such as tempered glass, insulating glass, coated glass, laminated glass, and glazed glass, which is difficult to count. The purpose of this paper is to analyze the development trend of the market, so instead of pursuing the accuracy of statistical data, we pay more attention to the comparison of years of data collection using the same statistical method, taking into account the impact of national policy guidance, and thus the future trend of architectural glass. With a view to providing reference for practitioners.

Estimated Market Capacity of China Construction Glass Market

The amount of glass used is calculated based on the building area completed each year, and the glass usage area is estimated based on the value of 20% of the building area:

In 2003, the new building area was 1.8 billion m2, and the estimated area of ​​window glass usage was approximately 360 million m2. In addition, the estimated glass plate production volume was estimated: In 2003, the area of ​​original glass used for construction was approximately 520 million m2. Including the use of the old house renovation, and then taking into account the need for double glass composite glass products such as hollow glass, which can also be roughly the total capacity of about 360 million m2, basically consistent with the above results.

Domestic high-grade glass usage statistics in recent years

Due to the existing data, only accurate statistical data for insulating glass and monolithic coated glass can be given. If the final product is in the form of coated insulating glass, the coated glass and insulating glass are counted separately. The following is the trend of statistical results in the past 5 years. Illustration.

The statistical results show that the average annual growth rate of the use of insulating glass in the past 5 years is greater than 40%, and the average annual growth rate of the use of coated glass (including Low-E glass) is greater than 13%. Today's focus is:

That is, the growth rate of the insulating glass is much larger than that of the coated glass, and it can be inferred that the use amount of the transparent hollow glass or the colored hollow glass is increasing rapidly.

Distribution of glass usage in each grade

According to the total capacity of the market and the amount of high-grade glass used, the distribution of glass usage in different grades was analyzed.

The analysis results show that the use of high-grade glass only accounts for about 3% of the total use of architectural glass, while the use of mid-range glass only accounts for 12% of the total use of architectural glass, and most buildings still use a lot of energy-saving properties. Poor low-grade glass.

Market demand for major products in 2007

Based on the above statistical results and predicting a conservative annual growth rate, the market capacity in 2007 is as follows: The amount of transparent insulating glass is more than 50 million m2, and it will be mainly used for residential houses. Due to the limitation of the national standard “Energy Efficiency Design Standards for Public Buildings” promulgated on July 1, 2005, public buildings projects will restrict the use of such glass except for remote areas and hard-to-monitor areas. The amount of newly-added coated glass (including Low-E glass) will be about 6 million m2, which will be mainly used for public building projects, and some will be used for civil residential buildings. This amount will be the output of 4 to 5 large coated glass production lines.

China's architectural glass market development trend

The author believes that the following factors can affect the development trend of the architectural glass market: the user's demand for comfort and awareness of energy-saving glass products; the support of national energy conservation policies, standards and regulations; the purchasing power support provided by the national economic development level; high-grade glass It is generally accepted that the price of products will be reduced to the market.

User demand trends

As the standard of living improves, the user's requirements for the building also increase. The requirements and expectations can be attributed to the following points: Energy efficiency is good - The used glass can save the cost of heating and air conditioning; The comfort is strong - The glass used has Good sound insulation performance, sufficient indoor lighting, summer solar radiation heat insulation, adequate insulation performance in winter, reliable quality - regular appearance, stable performance, and safety; reasonable price - reasonable price and can withstand. For the rich, comfort is more important, but for the general public, the low price is still extremely important.

National energy policy

The goal of building energy conservation proposed by the state is that by 2010, 1/3 of the nation’s newly added buildings will achieve the goal of energy conservation by 50%; by 2020, all new buildings in China will achieve the goal of energy saving of 65%. According to the 2010 target, an additional 3 billion m2 of energy-saving building area will be added in the next five years, involving an energy-saving glass area of ​​approximately 600 million m2, an average annual increase of approximately 120 million m2 of energy-saving glass, and the growth of insulating glass and Low-E glass. The rate will be pulled up. The trend of future usage of insulating glass that has been pulled up due to policy factors:

Whether the high growth of energy-saving glass (hollow) can be achieved depends on the government's supervision measures. Wu Yong, deputy director of the Department of Technology of the Ministry of Construction, proposed that energy-efficient buildings should use existing organizations to check on design audits, construction permits, completion acceptance certificates, and sales licenses, and they should be evaluated by professional organizations. Those that failed will not be issued. certificate. Qiu Baoxing, vice minister of the Ministry of Construction, pointed out at the press conference of the State Council in early 2006 that construction design and construction units that do not implement energy conservation standards will be punished and even cleared out of the construction market. The Ministry of Construction will supervise the construction process. However, the current supervisory implementation rules have not been perfected.

Glass variety development trend analysis

There are two possibilities for speculating the distribution of future varieties from the existing species distribution. The first is the average growth of glass grades of various grades. Obviously this is limited by policies; the second is the formation of energy-saving growth under the guidance of energy-saving policies.

According to energy-saving growth model, the future of insulating glass will increase dramatically, and the trend of application of specific glass products is: monolithic transparent glass, which currently accounts for 80% of the market. In the future, it will be replaced by a higher-level glass variety; Glass, with an annual growth rate of more than 40%, is projected to grow by more than 60% after 2007, becoming the mainstream product for growth, and the basis for further upgrading of glass usage; monolithic coated glass is restricted to parts of the economically underdeveloped regions. The use of public buildings will reduce their use year by year; heat-reflective coated insulating glass will replace monolithic coated glass in the field of public buildings and will continue to develop in the future, but the annual growth rate will gradually reduce and eventually be hollowed out by Low-E. Replaced by glass; Low-E insulating glass will become the preferred and mainstream product for public buildings. With the reduction of manufacturing cost, it will be widely used in residential residential buildings instead of transparent hollow glass and colored hollow glass.

The Direction of Development of Architectural Glass in China

China's architectural glass manufacturing industry has its own advantages

China's glass manufacturing industry has made considerable progress in recent years. In particular, the technological progress in the field of deep-processed glass is even more pronounced. The introduction of new production equipment and the local production of some equipment have laid the foundation for the future development of the entire glass industry. . At present, there are 125 production lines for float glass products, and the production capacity is huge. Insulating glass has formed a high- and mid-scale scale production pattern. Coated glass has enough production space to meet the market's needs. In addition, the production of various glass types is fully equipped and produced. Basically, raw materials can be used locally. In terms of technology, the Hardware is synchronized with the international production equipment. The software has the same level of technology as the international one. The overall advantages are obvious.

Current situation and problems

Despite the overall manufacturing advantages, the problems are also very prominent. First of all, the level of production and processing technology is uneven, high-quality products can be exported into the international market, low-quality products do not even meet national standards; Second, large-scale deep processing products are concentrated in the field of public buildings, the entire industry for residential energy-saving glass The cultivation of the market is not enough, and the backbone enterprises have insufficient investment in the residential energy-saving glass market. Third, the export volume of high-grade building glass products is limited and the export scale has not yet been formed.

Response measures and direction of development To meet the needs of the future development of the architectural glass market, the Building Glass Industry Association should provide a platform to strengthen the technical exchanges and cooperation among production companies and improve the production technology level of the entire industry, especially small and medium-sized enterprises. Accelerating the shift of high-end energy-saving products - Low-E hollow glass to civilian residential areas, utilizing the advantages of large-scale glass manufacturing enterprises for large-scale production of Low-E glass, small and medium-sized glass processing companies have the advantage of manufacturing large quantities of hollow glass, and taking the form of cooperation to scale Expanding the production capacity of Low-E hollow glass, the advantages complement each other to reduce the cost and scale, and accelerate the energy-saving glass to the civilian residential area. In order to avoid the disorderly competition in the domestic market, large-scale glass manufacturers should enhance the competitiveness of the international market, and create a large-scale composite glass products to the international market.
