Application of heat insulation aluminum plate in construction field

Insulation aluminum plates have been used in the construction field for more than 100 years. The main advantage of aluminum plate is that the use of thermal insulation aluminum plate in the building can reduce the weight of the building structure; reduce the transportation cost of building materials and the workload of building installation; improve the low temperature reliability and service life of the structure; expand the utilization rate of the house by aluminum plate; achieving high building quality. Therefore, the construction industry at home and abroad is also increasingly using 3mm china insulation aluminum sheets and aluminum alloy materials.

At present, in some countries, the construction industry has become one of the three major users of aluminum (container packaging, construction, transportation), which accounts for more than 20% of the world’s total aluminum consumption. In recent years, China’s construction industry has developed rapidly. The proportion of aluminum structures in buildings is increasing. The aluminum for building structure mainly includes the light structure of the building, the envelope structure of the roof and the wall, the skeleton, the door, the window, etc., as well as the decorative and functional application of the ceiling, the veneer and the sun visor. Scaffolding, pedals and cement prefabricated formwork for building factories often use aluminum and aluminum alloys to reduce weight. Removable, mobile temporary buildings and facilities more favor aluminum alloys.

The most important high quality insulation sheets used in the construction field are: extruded profiles of Al-Mg-Si alloys, accounting for about 80% of all aluminum and aluminum alloy profiles. The main grades involved are 6063 and 6061 aluminum sheet. In recent years, low-component Al- Extruded profiles of Zn-Mg alloys (7003 and 7005) are also being promoted. The various sheets are mainly Al-Mn and Al-Mg alloys, such as 3A21 and 3004 alloy cold rolled sheets and industrial pure aluminum sheets. In addition, other series of alloys and grades are also used in the construction sector, depending on the requirements of use.
