An important indicator of the energy consumption of the retractable door, for example, the current standard in Europe is K = 1.1-1.3w / m2.k, while China's highest standard of Beijing is K = 2.8w / m2.k, only the equivalent of Europe in 1984 Of the standard, while most provinces and cities have not developed the relevant standards, behind nearly three decades, the gap is amazing.

One has to admit the reality is that the vast majority of China's retractable door business is still hand-style workshop, low-end production status for many years has not changed. In Europe and the United States developed countries, the use of high-grade energy-saving retractable door has reached the proportion of the total expansion of 67% (the rest of the ordinary energy-saving retractable door), and China, the implementation of the highest technical standards in Beijing and developed countries, ordinary energy-saving retractable door difference of 15 years , High-end energy-saving retractable door use only 0.5% of the total amount of retractable door.

In addition, developed countries in Europe and America, has long been formed a number of retractable door professional market, such as Germany Nuremberg, Hannover, Las Vegas, the United States, the annual turnover of up to 200 billion US dollars. In China, retractable door industry has not yet a professional market, still remain in the initial stage of short-term exhibition, and the rapid development of retractable door industry and market demand is very inconsistent.
