How about the quality of the ceiling
Aluminum cords board ceiling quality is good, buy aluminum slab ceiling, look at the aluminum, film, back cover, from these three aspects to test the quality of aluminum gusset, AIA integrated ceiling quality in this area.
First, check the aluminum material, because the average consumer is difficult to see the aluminum material, it is recommended that consumers look at the hardness of the buckle plate, and then check the paint is smooth, no burr, with or without color.
Second, look at the film, the consumer can pull the edge of the board, if the phenomenon occurs from the film that is, this film is not close with the buckle plate; again look back cover (buckle back), which is a lot of consumers Ignore a part. Back cover generally have to be anti-corrosion treatment, hand to pull, if the back cover can pull out the description of its material is not good; and the general manufacturers will be in the back of the inkjet manufacturers logo and production date, through the presence of these words, Consumers can also identify the product is good or bad. If there are, that it is a regular factory of the machine production, is different from the small workshop, the quality is relatively guaranteed.
The second generation of PVC is the first generation of the product.
While the metal ceiling aluminum plate is better, the current market is also divided into the following points:
The first type of aluminum-magnesium alloy, which contains some of the manganese, the biggest advantage of the material is good antioxidant capacity, and because adding the right amount of manganese, the strength and stiffness to improve, is the best material ceiling.
The second type of aluminum - manganese alloy, the strength and stiffness of the plate is slightly better than the aluminum - magnesium alloy, but the antioxidant capacity is slightly inadequate;
The third type of aluminum alloy, the plate contains manganese, magnesium less, so its strength and stiffness are significantly lower than the aluminum-magnesium alloy and aluminum-manganese alloy, antioxidant capacity in general.
