In terms of material production, they are different. The painted keel is made of iron. The aluminum alloy keel is made of aluminum. In terms of technology, they are also different. Baking keel is simpler than aluminum alloy, but the machine it is made of is very strict, beautiful and supportive. As a ceiling material, it is matched with calcium silicate board.
Which of the two is more advantageous, obviously the aluminum alloy keel, because the aluminum alloy keel does not change color, rust, change color, corrosion resistance and erosion resistance after painting. Even if it is used for the ceiling of outdoor corridor, there is no quality problem. The raw material of painted keel and painted keel is iron, which is easy to rust, taste and paint. After a long time, all the problems will appear, especially if it can't be used in wet places. Therefore, the aluminum alloy keel is used as a matching with the calcium silicate board in the general bathroom. Because aluminum alloy keel can also be waterproof and moisture-proof.
But the only thing is, you can't deny the advantages of painted keel! The price of painted keel is cheaper than that of aluminum alloy keel, ranging from 6- 12 pieces per square meter, and the lowest price of aluminum alloy keel ranges from 6.5- 15 pieces. In contrast, each has its own advantages!
Characteristics of painted keel; Moisture-proof, anticorrosive and colorfast; The product precision is high, the main keel and the secondary keel are strictly symmetrical and closely matched; Strong bearing capacity, no deformation, no fracture; Convenient installation, saving installation time and reducing labor cost; The models and specifications are complete, which can meet the diversified needs of customers; The products are good in decoration and rich in decorative colors, and the colors such as crescent white, Pacific white and black meet the personalized design.
Product classification: plane painted keel: the decorative surface is made of matt coated steel strip with fine texture and no color difference; Multi-roll forming, smooth surface; High strength, simple and quick installation. Narrow-edge plane painted keel: simple and generous in shape, excellent in seismic performance; Light weight, simple and quick installation. Trough-shaped painted keel: there are two kinds of trough shapes, black and white, which have a strong three-dimensional sense; The installation is convenient and the system is firm, which can replace the T-shaped aluminum alloy keel. Three-dimensional groove painted keel: using double-sided painted steel strip as raw material, the color is soft, the lines are clear and the three-dimensional effect is strong; With high dimensional accuracy and close cooperation, it can be used with metal ceiling and mineral wool sound-absorbing board, and it is a classic product of indoor ceiling in modern buildings.
The above is Bian Xiao's detailed answer. I wonder if you are satisfied with our introduction.
