In recent years, many new building materials such as aluminum alloy materials and plastic steel materials have gradually emerged and quickly occupied the building materials market. In recent years, whether it is a commercial house developed by a real estate developer or a house built by ordinary people, the choice of door and window materials has made the choice of alloy products rich, the quality is complete, the wooden doors and win dows are gradually replaced by alloy doors and windows, now in addition to decoration In addition, the proportion of wooden doors and windows is getting smaller and smaller. That is why, why the doors and windows that the Chinese have used for thousands of years will be replaced by alloy doors and windows made of alloy aluminum sheets for several years. The reason is very simple, that is, the doors and windows made of alloy materials are more than the wooden doors and windows. There are many advantages, specifically the following two main points:
First, the alloy doors and windows made of alloy aluminum plate are relatively clean and have good sealing performance. In the north of China, the winter is cold and hot in summer, and warmth has become the primary consideration for people to design houses. In the past, wooden doors and windows were not only cumbersome, but also had poor thermal insulation performance. Competition with alloy doors and windows with extremely tight sealing would naturally fail. Therefore, house builders will naturally choose alloy doors and windows that have better warmth.
Secondly, the cost of alloy doors and windows is low and the raw materials are wide. The wooden doors and windows are made of high-quality wood, which is costly and will cause damage to the forest. Alloy doors and windows, especially aluminum alloy doors and windows, are less expensive and have a wide range of raw materials, which is welcomed by merchants.
