What is the current situation of space frame structure houses?

In the first 30 years of the 21st century, China will maintain a certain scale of new housing every year. At present, the quantity, variety and quality of construction steel in China can meet the needs of space frame steel structure residential buildings. Now, the state has strengthened its policy guidance and support for steel structure housing, and the technology of space frame steel structure housing has been developing day by day. In China, the conditions for the development of space-framed steel structure residences are already available. Although energy-saving, environmentally-friendly, and land-saving space-framed steel structure residences have received increasing attention in China, there is still a big gap in the degree of promotion compared with developed countries in the world. According to the person in charge of the relevant industry association, the current proportion of steel structure housing in China is less than 5%, while in developed countries it is generally more than 40%. More than 50% of China's steel is used in the construction industry. The total amount of steel used in construction last year reached about 170 million tons, most of which were used in traditional reinforced concrete structures, and more than 10 million tons were used in steel structure residential buildings. The space frame steel structure house with new wall materials can increase the energy saving efficiency by half, increase the effective use area by 6% to 8%, shorten the construction period, save construction water, conform to the development direction of the national industrial policy, and achieve the most energy saving and land saving. One of the best housing forms.
