t is obvious that aluminum profiles for doors and windows bring us energy-saving benefits. At present, in the vast majority of buildings in China, more than 90% are high energy consumption buildings, and in high energy consumption buildings, the energy consumption of doors and windows accounts for nearly half. Therefore, it is not only the objective requirement of China's energy situation, but also the inevitable trend of market development to adopt energy-saving bridge broken aluminum doors and windows and carry out bridge broken aluminum transformation for existing building door and window manufacturers.
As a keen catch of aluminum profile manufacturers, in order to alleviate the contradiction of energy constraints and environmental pressure, the state will increase support in the field of energy saving and low carbon. For example, the national development and Reform Commission issued a medium and long-term special plan for bridge broken aluminum, which is a medium and long-term plan for bridge broken aluminum formulated in China since the reform and opening up.
Therefore, a large number of energy-saving and environment-friendly aluminum profile products such as bridge broken aluminum profile, profile doors and windows are constantly emerging, new products emerge one after another, long service life and good decorative effect are also the reasons why they are more and more favored by consumers. The commonly used door and window profiles are aluminum alloy profiles, wood profiles, plastic profiles, steel profiles and glass profiles. Wooden doors and windows are easy to manufacture and suitable for manual production, which has been a popular choice. Steel doors and windows have strong hardness, small cut-off surface, less shading, and can prevent fire. Through continuous improvement, steel doors and windows materials can produce a variety of specifications and products.
Moreover, China is in the peak period of construction, with nearly 2 billion square meters of housing area built every year, which is more than the total annual building area of all developed countries. However, it can not be ignored that more than 97% of the buildings are high energy consuming buildings. If we calculate based on this, it is estimated that by 2020, the national high energy consuming building area will reach 70 billion square meters (the above estimation is only for reference). Therefore, Shangzhi aluminum believes that if we do not pay attention to the design of building broken bridge aluminum, it will directly aggravate China's energy crisis.
