The substrate of metal ceiling is generally aluminum plate, steel plate, galvanized plate, etc. The most common is aluminum alloy, which is called aluminum gusset plate by most building materials manufacturers. It is characterized by rich and bright colors, durable colors, good oxidation resistance, light weight, no mildew, no discoloration, high flatness, no cracking problems, detachable replacement and so on.
At present, there are strip-shaped aluminum gusset plates, square-shaped aluminum gusset plates and metal grids on the market, among which strip-shaped aluminum gusset plates have the widest application range and many manufacturers, and different specifications can be seen. The approximate specifications of strip-shaped aluminum gusset plates are as follows: the length is generally 3 meters and 4 meters; There are many specifications with a width between 3 cm and 30 cm; The thickness of the plate is generally between 0.4 and 0.9 mm, and the market price is 50 ~ 400 yuan/m2.
Generally, there are two places to install aluminum buckle ceiling in home decoration, one is bathroom and the other is kitchen. At this time, it is necessary to carefully consider the choice of aluminum button ceiling.
■ There are many kinds of aluminum gusset plates on the market, but generally there are only two kinds: color flat plates and white hollowed-out patterns. So, what problems should we pay attention to when choosing?
The bathroom ceiling should be hollowed out.
After installing the ceiling in the bathroom, the space height of the house will be reduced a lot (the sewer pipe upstairs will be sealed on the ceiling). When taking a bath, especially in winter, water vapor will spread around. If the space is narrow, people will soon feel oppressed, and people with poor health may even be in danger, but it will undoubtedly be too cold to circulate air with a fan.
At this time, the hollow ceiling will play a very good role, it will make water vapor evaporate upward without obstacles, and at the same time, because of its thin pattern isolation layer, there will be a temperature difference between the air in the upper and lower spaces. After the water vapor rises to the ceiling, it will quickly condense into water droplets, and it will not drip down and fall on people. It can be said that it has a dual role.
The ceiling of the kitchen should be flat.
First, there are many color choices, which can make your kitchen have different charm and give yourself a good mood; The second is good cleanliness, which is the most important. In the kitchen, there will inevitably be a lot of lampblack. Even if you cook less, you will obviously find that the color of the kitchen is dim after one or two years. When you want to clean, the ceiling is a very important part, and there will be almost 70% to 80% oil smoke on the ceiling.
If you choose a hollow ceiling in your home decoration, you can't clean it, because the lampblack has penetrated into the hollow ceiling, and the flat ceiling does not have this problem. Wipe it with a cloth or brush it, and it will be fine soon.
■ Make clear the types to be purchased, and then purchase the building materials market. So how to judge the quality of aluminum gusset plate?
1 Judging the base material: Take two different aluminum gusset plates, beat the base material, listen carefully and compare their sounds. The crisp sound means that the bottom material is good, and the muffled sound means that there are many impurities.
2. Judge the surface: find a short sample and break it repeatedly to see if its paint surface falls off or peels off. A good aluminum gusset plate only has cracks on the paint surface, and no large pieces of paint will fall off; In addition, a good aluminum gusset plate has paint on both sides, because the back is often worse and wetter, and the aluminum gusset plate with paint on the back has a longer service life.
3. Judging the keel: The material of the keel is generally galvanized steel plate, mainly depending on the flatness and smoothness of its processing; You can also check the keel accuracy marked in the manual. The smaller the error range, the higher the accuracy and the better the quality.
■ Friendly reminder: When buying aluminum gusset plates, you should also know that good manufacturers often provide perfect after-sales service. You should pay attention to:
1. Ask the manufacturer whether the ruler processing is negative. Because the length of domestic strip aluminum gusset plate is generally 3 ~ 4 meters, there will be a certain waste of materials if it is not cut to length; Cut-to-length processing is customized by sales staff according to the size of your home, and there is no wave.
2. Determine whether the factory charges for on-site measurement. In addition, the complete design should take into account your pipeline, ventilation and lighting problems, and make construction drawings to ensure the construction quality.
3. Determine whether the manufacturer delivers the goods to the door to solve the transportation problem.
4. Determine whether the manufacturer charges for on-site installation.
5. Determine the warranty of the manufacturer's products.
