It is very similar to aluminum alloy keel in appearance and is also a commonly used material for suspended ceilings. Its function is the same as that of aluminum alloy keel, which is also for beauty and plays a supporting role. It is matched with calcium silicon board and mineral wool board, etc.
In daily life, the so-called paint keel refers to the iron paint keel, and the aluminum alloy keel can also be called aluminum alloy paint keel, but for convenience, a few words are omitted, just like American English, which likes abbreviations. So the paint keel refers to the iron paint keel, and the aluminum alloy paint keel is called aluminum alloy keel.
In terms of material production, the two are different. The raw material of the paint keel is iron. The aluminum alloy keel is made of aluminum. In terms of craftsmanship, the two are also different. The paint keel is simpler than the aluminum alloy process, but the requirements for its production machine are very strict. It is also beautiful and supportive. As a suspended ceiling material, it is matched with calcium silicon board.
Which one has more advantages? Obviously, it is the aluminum alloy keel. The reason is that the aluminum alloy keel is processed and does not fade, rust, or change color after baking paint. It is resistant to corrosion and erosion. Even if it is used for the ceiling of the outdoor corridor, there is no quality problem. The raw material of the baking paint keel is iron, which is easy to rust, change, and lose paint. All problems will appear over time, especially it cannot be used in humid places. Therefore, aluminum alloy keels are generally used in bathrooms as a match with silicon calcium board. Because aluminum alloy keels are also waterproof and moisture-proof.
But the only point is that the advantages of baking paint keels cannot be denied! The price of baking paint keels is cheaper than that of aluminum alloy keels, ranging from 6 to 12 yuan per square meter, while the price of aluminum alloy keels ranges from the lowest 6.5 to 15 yuan. In comparison, each has its own advantages!
