What should I pay attention to when buying an aluminum plate?
Aluminum slab plate thickness of the optimistic, do not be out of the bag. There are no stains on the paint surface
(1) to view its aluminum thickness. The thickness should not be less than 0.6 mm, or likely to cause the phenomenon of collapsed waist. When choosing to pay attention to whether the business through the thickening of the paint layer to increase the overall thickness, this aluminum plate do not buy. (2) check the true quality of the material to prevent illegal manufacturers of stainless steel fake aluminum, pure aluminum or impure aluminum or stainless steel iron, you can use the magnet to verify that pure aluminum does not magnetize, and times Quality aluminum or false aluminum can absorb magnetic. (3) to identify the aluminum plate in addition to pay attention to the surface finish, but also to observe the thickness of the board is uniform, whether double-sided paint, pinch the board feel, flexibility and toughness is good enough.
1, aluminum plate quality is not good in its thick thickness, but rather the texture of aluminum. Some of the no-name products are used in the aluminum cans, because the aluminum is not good, the board can not be evenly thin, can only do some thick. To prevent bad businessmen deliberately deceive, not thick aluminum plate on a certain quality.
2, home decoration with aluminum plate thickness of 0.6 mm is enough to use, because home improvement with the aluminum plate, the length of less than 4 meters, and there is no heavy furniture on the ceiling. Only in the project with the aluminum plate will be longer, which is mainly to prevent deformation, so use thicker (0.8 mm above), the hardness of some of the aluminum plate.
3, take a sample beat a few times, if the sound is brittle, indicating that the product substrate is good; if the sound boring, indicating that the product more impurities.
4, take a sample repeatedly broken off to see if it is off the paint, from the skin. If it is a good quality aluminum plate, the paint will only crack, there will not be large pieces of paint off. Good aluminum slabs are on the back of the paint, because the back of the environment is generally more humid, with lacquered aluminum slab plate life than only single-sided aluminum slab longer.
5, to prevent the business "gnawing column." Coated film and roller coating from the appearance of the difference is not good, but the price is very different.To prevent some bad business to take roller coated board plaster board, available lighter will Board blackened, covered with easy to wipe the black stains, and rolling board no matter how rub will leave traces.
6, aluminum buckle keel material is generally galvanized steel, to see its flatness, the degree of smooth processing, keel the higher the accuracy, the better the quality.
