Analysis of the downstream industry chain of metal carved panels
Section 1 Analysis of Upstream Industry Development Status
The main raw materials of metal carved panels are polyurethane and alloy steel plates.
1. Polyurethane
1) Overview
Polyurethane (PU) resin is a polymer with repeating structural units of urethane segments made by the reaction of isocyanates and polyols. PU products are divided into two categories: foam products and non-foam products. Foam products include soft, rigid, and semi-rigid foam; non-foam products include coatings, adhesives, synthetic leather, elastomers and PU elasticity. fiber, etc. Polyurethane materials have excellent properties, are widely used, and have many types of products. Among them, polyurethane foamed plastics are the most widely used.
2) Production status
my country's polyurethane industry started in the late 1950s and developed slowly in the following 20 years. In the 1990s, with the introduction of 10,000-ton-scale large-scale isocyanate and polyether equipment, my country's PU industry entered a stage of rapid development. By 1998, the output of PU raw materials reached 298,000 tons, and the total output of products reached 650,000 tons. From 1989 to 1998, the output of PU raw materials increased by an average of 28% annually, and the output of PU products increased by an average of 23%. The variety of raw materials and products has increased to more than 200, and the quality, application scope, scientific research and development level and ability have been comprehensively improved. At or close to international standards.
In 2001, the output of raw materials was 430,000 tons, and the output of finished products reached 1 million tons. The PU industrial system has been initially formed. In 2007, China's polyurethane output reached 3.4 million tons, of which foam output accounted for 56% of the medium output, exceeding 1.9 million tons. From 2000 to 2007, China's polyurethane industry developed rapidly, with an average annual growth rate of 35%.
3) Demand situation
Five aspects will drive future development:
In the future, the development of my country's polyurethane industry will be mainly driven by five aspects, namely total population, automobile industry, building energy saving, environmental protection requirements, and leisure and entertainment industry.
In terms of population, my country is a country with a population of 1.3 billion. The increase in per capita consumption will inevitably bring about a larger increase in the total consumption of polyurethane.
In the automotive industry, the development of the automotive industry has promoted the technological progress of polyurethane, and polyurethane has continuously provided newer and better materials for the automotive industry. According to statistics, in 2005, my country's automobile production was 5.7 million, and the proportion of cars had reached 48.49%. Experts predict that my country's auto industry will continue to maintain steady development, with a growth rate of 10% to 15%. By 2010, China's auto output will reach 9.81 million units, surpassing Japan's annual output of 9.6 million units. By then, China will become the world's second largest auto producer after the United States. The rapid and stable development of my country's automobile industry can greatly promote the development of the polyurethane industry.
In terms of building energy conservation, according to statistics, 65% of the consumption of MDI in the United States is used for building insulation, while the MDI used for building insulation in my country accounted for less than 10% of the total consumption of polymerized MDI in 2004, which is far lower than the global and international consumption. average for developed countries. Due to the requirements of energy and environmental protection, the Chinese government has enforced building energy conservation codes and standards, requiring that the total energy consumption of urban buildings in 2010 should be reduced by 50%; in 2020, the total energy consumption of urban buildings should be reduced by 65%. To achieve this goal, the polyurethane material with the best thermal insulation performance must be used, which is undoubtedly a great opportunity for the promotion and application of polyurethane rigid foam.
With the improvement of environmental protection requirements, the development of the polyurethane industry requires the reduction or elimination of 'three wastes' pollution, the renewable utilization of resources, especially the reduction or elimination of the use of organic solvents. At present, the use of organic solvents in polyurethane is mainly concentrated in the fields of coatings, adhesives, synthetic leather slurries, etc. Therefore, the use of water instead of organic solvents to make water-dispersible coatings, adhesives and synthetic leather slurries has become the research and development of today's polyurethane industry. hot spot. With the increasingly strict national environmental protection regulations and standards and the improvement of people's awareness of environmental protection, water dispersible polyurethane will be widely used in the fields of ecological adhesives for wood, leather pulp, adhesives for shoes, textile coatings and treatment agents, coatings, etc. application and have broad prospects for development.
In terms of leisure and entertainment, statistics show that my country's consumption of MDI for leisure and entertainment has increased from 115,000 tons in 1997 to 240,000 tons in 2005, with an average annual growth rate of 9.6%. In the future, with the development of society and economy, it is expected that the application of polyurethane in the leisure and entertainment industry will develop rapidly.
2. Alloy steel plate
With the development of science, technology and industry, higher requirements are put forward for materials, such as higher strength, high temperature, high pressure, low temperature, corrosion resistance, wear resistance and other special physical and chemical properties. To meet the requirements, alloy steel plates appeared.
According to statistics from relevant authoritative departments, the demand for hot-dip galvanized steel sheets in my country is increasing every year, but the self-sufficiency rate is only about 50%, and the remaining 50% is solved by imports. For example, in 2000, my country produced 1.7 million tons and imported 1.85 million tons. . In 2001, 2 million tons were imported. According to the statistics of the Marketing Department of the State Metallurgical Bureau, the domestic demand for coated steel sheets in 2005 reached more than 4 million tons. The aluminum-zinc alloy coated steel plates are all imported from abroad. By 2007, only Baosteel produced aluminum-zinc alloy steel plates in China.
The development of aluminized steel sheets can be traced back to the 1930s. In 1930, the United States first used the hot-dip method to produce aluminized steel sheets. In 1939, the Sendzimir production line of Amco Steel Company in the United States was put into production, and the product name was set as "Ahim-zin. steel" at that time. This technology has been adopted in various countries since then. In 1962, the British Iron and Steel Research Association (BISRA) proposed the electrophoretic aluminum plating method, and in 1972, the British Steel Corporation (BSC) built the first continuous electrophoretic aluminum plating production line for strip steel. Since the 1970s, with the development of the automobile industry, the production technology of aluminized steel sheets has developed rapidly, and some new methods and technologies have emerged, such as electroplating, spray plating and vacuum evaporation, etc. The main method of producing aluminized steel sheets in various countries, because this method is more economical. In order to further improve the corrosion resistance of aluminized steel sheets, the American Bethlehem Company developed Galvalume in 1964 and put it into industrial production in 1972.
Since aluminized steel plate has both the strength of steel and the corrosion resistance, oxidation resistance and heat reflection properties of aluminum, it has been widely used in the automotive industry, construction industry, household appliances and other fields. Subfloors and embossed interior panels, used as unpainted corrugated roofing panels for metal buildings, box panels for various home appliances such as ovens, dryers, and air conditioners.
Section 2 Analysis of the Development Status of Downstream Industries
Downstream Industry - Construction and Real Estate Industry
Since the 16th National Congress of the Communist Party of my country, investment in the construction of basic industries and infrastructure projects in China has grown rapidly. From 2003 to 2006, the total investment in fixed assets in basic industries and infrastructure construction was 12,027.1 billion yuan, nearly double the amount from 1978 to 2002; the average annual growth rate was 26.1%, 15.7 percentage points higher than the average annual growth rate of the national economy over the same period.
Since the 16th National Congress of the Communist Party of China, the central government has increased investment in basic industries and infrastructure in the central and western regions. In 2006, the basic industries and infrastructure construction projects in the central and western regions increased by 6.4 percentage points compared with 2002;
In recent years, a number of super-large projects such as the West-East Gas Pipeline, the South-to-North Water Transfer Project, the Qinghai-Tibet Railway, and Olympic venues have been completed or are under construction, marking that the construction capacity of my country's construction industry has reached a new level. The construction of residential projects and municipal infrastructure has been accelerated, greatly improving the appearance of the city and meeting the needs of the people for housing. All localities attach great importance to the reform and development of the construction industry. At present, nine provincial and municipal governments have successively issued policy opinions to promote the development of the construction industry. The pace of structural adjustment of large and medium-sized construction enterprises has been accelerated, the efficiency of enterprises has been gradually improved, the comprehensive strength has been continuously improved, and the international competitiveness has been significantly enhanced, which has promoted the rapid development of my country's construction industry. From 2002 to 2006, the total output value of the construction industry increased from 1,852.7 billion yuan to 4,097.5 billion yuan, with an average annual growth rate of 120%, and the added value of the construction industry exceeded 1 trillion yuan for two consecutive years. Among the 20 industries in the national economy, the construction industry ranks 5th. The role of the construction industry as a pillar industry in the national economy is more obvious. In addition, my country's construction industry has grown continuously, and the number of migrant workers in rural areas accounts for one-third of the total number of rural migrant workers, which has become an important channel to solve farmers' employment and increase farmers' income, and promote the coordinated development of urban and rural areas. The total amount of foreign project contracting business, market scope, and professional fields are constantly expanding, and its business covers more than 160 countries and regions around the world.
In the first half of 2007, due to the acceleration of urbanization, the construction of new socialist countryside, the upcoming Olympic Games, the official start of energy conservation and emission reduction, and the completion of the main road framework before the year, the investment and development momentum was further released. Local governments and enterprises are actively investing in urbanization construction and energy conservation and emission reduction construction. Affected by the above factors, the construction industry has also developed rapidly. According to statistics from the National Bureau of Statistics, in the first half of this year, the total output value of China's construction industry was 1,821.3 billion yuan, a year-on-year increase of 22%. Statistics show that in the first half of this year, the construction area of housing construction enterprises in the national construction industry was 3.08 billion square meters, a year-on-year increase of 16.9%.
In the first half of 2007, due to the accelerated growth of my country's macro-economy and fixed asset investment, the construction industry is still booming. It is expected that in the second half of the year, under the influence of factors such as rapid economic development, growth in fixed asset investment, accelerated urbanization, "three rural" work, and energy-saving construction, my country's construction industry will maintain a relatively rapid development momentum. Attention should be paid to important construction markets such as urban infrastructure construction, transportation construction, real estate construction, and water conservancy facilities construction.
In 2008, the construction industry maintained a high level of prosperity, and various indicators of the industry grew steadily. As an industry highly related to fixed asset investment, the state's policy of stimulating economic growth with investment will drive the growth of the construction industry.
As one of the country's pillar industries, the construction industry is also a typical investment-driven industry. In the annual fixed asset investment composition, the proportion of construction and installation projects has always been stable at more than 60%. With the fluctuation of the national economic cycle and the implementation of macro-control policies, the construction industry is characterized by cyclical fluctuations. In the current context of economic growth driven by investment, the construction industry has ushered in a rare opportunity for development.
In the first three quarters of 2008, the total output value of the construction industry completed by the national construction enterprises was 3,755.2 billion yuan, a year-on-year increase of 22.8%. National construction enterprises completed housing construction area of 4.372 billion square meters, a year-on-year increase of 15.6%. The construction industry realized a total profit of 83.5 billion yuan, a year-on-year increase of 26.8%. The whole industry realized the newly signed contract value of 4,183.62 billion yuan this year, a year-on-year increase of 25.2%. The industry maintained steady and rapid growth. In the past few years, the construction industry climate index and industry entrepreneur confidence index have maintained an upward trend. In the second half of 2008, due to the impact of the international financial turmoil, the industry climate index and entrepreneur confidence index declined slightly.
As one of the pillar industries of the country, the construction industry is also a typical investment-driven industry. In the annual fixed asset investment composition, the proportion of construction and installation projects has always been stable at 60%. Running at a high level of industry prosperity, the construction industry's contribution to GDP Contribution was stable at around 6%. It can be seen from this that most of the investment in fixed assets must be transformed through the construction industry, and the scale of investment in fixed assets largely determines the scale of the construction industry.
In 2008, the global financial crisis caused by the subprime mortgage crisis in the United States continued to spread, resulting in a sharp decrease in overseas market demand and a sharp contraction in export volume. Domestic consumption is also difficult to achieve rapid growth in the short term. In this case, in order to achieve the policy goal of "maintaining growth", investment has become an important means of stimulating economic growth. From increasing investment in railway construction to the rumored 5 trillion yuan To complete the project construction in these measures, it is estimated that an investment of about 4 trillion yuan will be required by the end of 2010. At the same time, the central government emphasized that "expanding investment must be quick, heavy, accurate, and solid," fully demonstrating the government's strength and determination to increase infrastructure investment. With the increase in investment, the construction industry has ushered in a rare opportunity for development.
In 2008, under the influence of macro-control, the real estate industry entered a downturn area, the growth rate of the purchased land area and the newly started area both declined, and the sales area and sales of commercial housing also showed a downward trend year-on-year, showing that the real estate industry is still facing a very difficult situation. Severely, there is still uncertainty about whether the industry can get out of the trough in 2009. Affected by the real estate industry, there is uncertainty about the trend of the housing construction industry in 2009.
