Galvalume sheet is an alloy structure. Its main components are aluminum, which accounts for about 55%, and zinc is 43.4%. In addition, 1.6% of silicon is added, and zinc is 43.4%. In addition, 1.6% of Silicon is added, and then a sheet is formed after high temperature. Its corrosion resistance is very outstanding, and its durability is also very excellent.
It has thermal reflectivity and good heat resistance. Compared with galvanized sheet, the price is slightly more expensive, but the service life is longer, so the cost performance is also very high.
The thermal reaction performance of galvalume sheet is very high, more than twice that of galvanized steel sheet, so it can be used as a thermal insulation material. In addition, it can withstand high temperatures of more than 300 degrees, and can be used in chimney pipes or fluorescent lampshades, etc.
In addition, it is easy to paint, has good adhesion, and can be painted without weathering treatment, so it can be painted directly on the board. In addition, the processing performance and spraying performance are very superior, and can be used in construction, including automobiles, home appliances, etc.
The difference between galvalume sheet and galvanized sheet
1. The main difference between the two is the difference in the coating. A layer of new material is distributed on the surface of the galvalume sheet, which can play a protective role and increase its corrosion resistance.
2. The surface of the galvalume sheet is composed of aluminum, zinc, and other elements, and it is honeycomb-shaped, which can also play a protective role in this case. Once it is cut, the problem of corrosion is likely to occur, so if you choose this kind of plate, you must cut as little as possible, so as to prolong the service life.
3. If you want to cut, you need to protect the edge, such as brushing anti-rust paint, so that the service life can be longer and corrosion is not easy to occur.
