In the 21st century, the steel structure industry has been developing rapidly and shows great vitality. Steel structures are widely used in industrial buildings because of their unique anti-seismic capability, fast construction speed, economic and practical advantages, which meet the requirements of green environmental protection. With the rapid increase of the permanent resident population and the foreign population, it is urgent for China to develop low-energy buildings, residential buildings and industrial buildings.
At present, the industrial construction industry has been faced with three major difficulties. First, the irrational initial planning leads to the blind demolition. Second is the quality issue of the industrial building itself, and third is the sustainability of the building itself. In industrial buildings, energy saving, land saving, water saving and material saving are very important. It is not only related to the problem of industrial energy consumption, but also related to the rational utilization of the limited resources on the earth. At present, more than 95% of the existing industrial buildings in Shanghai are high-energy buildings. Every year there is still more than 90% in the new industrial building belongs to the high energy consumption construction, if get promoted energy-saving and ground-saving steel structure, it has a positive effect to its social economic benefits and resources reuse of Shanghai. At present, China advocates to develop energy-saving and emission-reduction buildings.
Steel structure is with light weight, strong earthquake resistance, and the materials can be 100% recycled, truly green and pollution-free; The steel structure adopts high-efficiency energy-saving wall, which can reach 50% energy saving standard. The small area of the foundation reduces the large amount of land energy consumed in excavating the mountain. The fully industrialized manufacture of steel structure dry construction saves a lot of investment of water, electricity and human resources. And so on, a series of advantages of steel structure is the best choice for chemical industry construction, especially in Shanghai, where there are more people, less land and less industrial economy, and relatively developed industrial economy.
At present, European and American countries are constantly accusing China of being a user of high-energy buildings, and China should vigorously develop low-energy steel structure buildings, playing a role as a model for China. Under the current international situation and domestic policy adjustment, vigorously developing steel structure industry is a good way to solve high energy consumption industrial buildings in China.
