Market analysis of building glass industry development guess of energy-saving varieties

1.8 billion m2 of new building area was added in 2003. Therefore, it is estimated that the use area of window glass is about 3. 600million m2. In addition, the output of flat glass is calculated

except for flat glass, it has always been difficult to make statistics on China's construction glass market, especially on the production and sales of deeply processed glass, such as tempered glass, insulating glass, coated glass, laminated glass, colored glaze glass, etc. The purpose of this paper is to analyze the development trend of the market. Therefore, it does not pursue the accuracy of statistical data, but pays more attention to the comparison of data collected by the same statistical method for many years, and takes into account the impact of national policy guidance, so as to obtain the future trend of architectural glass, in order to provide reference for practitioners

estimation of market scale and total market capacity of China's building glass

the use of glass is calculated based on the building area completed each year, and the glass use area is estimated by 20% of the building area:

1.8 billion m2 of new building area was added in 2003, so the use area of window glass is estimated to be about 3. 600million m2. In addition, based on the output of flat glass, the area of the original glass used for construction in 2003 was about 5. 200million m2, including the use of old house renovation. Considering that the use of composite glass products such as insulating glass must be doubled, the total capacity can be roughly 3. 600million m2, basically consistent with the above results

statistics of domestic consumption of high-grade glass in recent years

limited by the existing data, only more accurate statistical data can be given for hollow glass and coated glass that only achieves upgrading. If the final product form is coated hollow glass, the coated glass and hollow glass are counted respectively. The following is the trend chart of statistical results in recent 5 years

the statistical results show that the average annual growth rate of the use of insulating glass in the past five 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:

that is, the growth rate of insulating glass is much greater than that of coated glass. Therefore, it can be inferred that the use of transparent insulating glass or colored insulating glass is growing rapidly

distribution of glass consumption of different grades

according to the total market capacity and the consumption of high-grade glass, the distribution of glass consumption of different grades is obtained through analysis

the analysis results show that the use of high-grade glass only accounts for about 3% of the total use of building glass, while the use of medium-grade glass only accounts for 12% of the total use of building glass. The vast majority of buildings are still hard and brittle: the tensile strength and elastic modulus are relatively high, and a large number of low-grade glass with poor energy conservation is used

market demand of main products in 2007

according to the above statistical results and the conservative annual growth rate, the market capacity in 2007 is predicted to be: the consumption of transparent insulating glass is more than 50million m2, which will be mainly used for civil residence. Due to the restrictions of the national standard "design standard for energy efficiency of public buildings" issued on july1,2005, the use of this kind of glass in public building projects will be restricted except in remote areas and areas difficult to monitor. At that time, the consumption of newly added coated glass (including Low-E glass) will be about 6million m2, which will be mainly used in public building projects, and some will be used in civil residential buildings. This amount will be the output of 4 ~ 5 large coated glass production lines

development trend of China's building glass market

the author believes that the following factors can affect the development trend of the building glass Market: users' demand for comfort and their cognition of energy-saving glass products; Support of national energy conservation policies, standards and regulations; Purchasing power support provided by national economic development level; The price of high-grade glass products can be generally accepted by the market

demand trend of users

with the improvement of living standards, users' requirements for buildings have also increased. Their requirements and expectations can be summarized as follows: good energy saving - the glass used can save the cost of heating and air conditioning; Strong comfort - the glass used has good sound insulation performance, sufficient indoor lighting, can isolate the solar radiation heat in summer, and can have sufficient heat preservation performance in winter; Reliable quality - regular appearance, stable performance and safety; Reasonable price - reasonable and affordable. Comfort is more important for the rich, but low prices are still extremely important for the general public

national energy conservation policy

the national goal of building energy conservation is that by 2010, 1/3 of new buildings in China will achieve the goal of 50% energy conservation; By 2020, all new buildings in China will achieve the goal of 65% energy saving. According to the target of 2010, about 3billion m2 of energy-saving building area will be added in the next five years, involving about 600million m2 of energy-saving glass, with an average annual increase of about 1. 200million m2, the growth rate of insulating glass and Low-E glass will be increased. Trend of future usage of insulating glass raised due to policy factors:

whether the high growth of energy-saving glass (hollow) can be realized depends on the government's supervision measures. Wu Yong, deputy director of the science and Technology Department of the Ministry of construction, proposed that energy-saving buildings should use the existing organizations to check the design review, commencement permit, completion acceptance certificate and sales permit. It is planned to be evaluated by professional institutions, and those unqualified will not be issued. Qiu Baoxing, Vice Minister of the Ministry of construction, pointed out at the press conference of the State Council at the beginning of 2006 that building design and construction units that do not implement energy-saving standards will be punished or even cleared out of the construction market. The Ministry of construction will supervise the whole construction process. However, the detailed rules for supervision and implementation are not yet perfect

analysis on the development trend of glass varieties

there are two possibilities to predict the future distribution of varieties from the distribution of existing varieties. First, the average growth of glass varieties of all grades is obviously restricted by the policy; The second is to form energy-saving growth under the guidance of energy-saving policies

according to the energy-saving growth mode, insulating glass will grow by an extraordinary large margin in the future. The application trend of specific glass varieties is: monolithic transparent glass, which currently accounts for 80% of the market, will be replaced by higher-level glass varieties in the future; Transparent insulating glass, with an annual growth rate of more than 40%, is expected to grow by more than 60% after 2007, becoming the mainstream product of growth and the basis for the re upgrading of glass usage; Single coated glass is limited to some public buildings in economically underdeveloped areas, and its use will decrease year by year; The heat reflective coated insulating glass will replace the single coated glass in the field of public buildings and will continue to develop in the future, but the annual growth rate will gradually decrease and eventually be replaced by Low-E insulating glass; Low-E hollow (1) computer is the control core glass of the whole device, and will become the preferred and mainstream product of public buildings. With the reduction of manufacturing cost, it will also be widely used in civil residential buildings instead of transparent hollow glass and colored hollow glass

the development direction of China's building glass

the existing advantages of China's building glass manufacturing industry

China's glass manufacturing industry has made considerable development in recent years, especially the technical progress in the field of deep-processing glass is more obvious, including the introduction and updating of production equipment, localized manufacturing of some equipment, etc., which have laid a foundation for the development of the whole glass industry in the future. At present, there are 125 production lines for float glass, with a huge production capacity; Insulating glass has formed a large-scale production pattern of high and medium grade; The coated glass has enough capacity space to meet the market demand; In addition, the production facilities of various glass varieties are complete, and the raw and auxiliary materials for production can be basically localized. In terms of technology, the hardware has production equipment synchronized with the international level, and the software has the same process and technology level as the international level, with obvious overall advantages

current situation and existing problems

although it has overall manufacturing advantages, the existing problems are also very prominent. First, the level of production and processing technology is uneven, high-quality products can be exported to the international market, and low-quality products do not even meet national standards; Secondly, large-scale deep-processing products are concentrated in the field of public buildings. The whole industry is not enough to cultivate the residential energy-saving glass market, and the backbone enterprises are not enough to invest in the residential energy-saving glass market; Thirdly, the export quantity of high-grade building glass products is limited, and the export scale has not yet formed

countermeasures and development direction in order to meet the needs of the future development of the building glass market, the building glass industry association should provide a platform to strengthen technical exchange and cooperation among manufacturers and improve the production technology level of the whole industry, especially small and medium-sized enterprises. Speed up the transfer of high-grade energy-saving products Low-E insulating glass to the field of civil housing, take advantage of the large-scale production of Low-E glass by large-scale glass production enterprises and the large-scale manufacturing of insulating glass by small and medium-sized glass processing enterprises, expand the production capacity of Low-E insulating glass in the form of cooperation, reduce the cost and form the scale by complementary advantages, and accelerate the promotion of energy-saving glass to the field of civil housing. In order to avoid disorderly competition in the domestic market, large glass production enterprises should strengthen the competition in the international market and create a situation in which high-grade composite glass products go to the international market on a large scale
