At present, the domestic market for aluminum buckles is mixed and disorganized. Many manufacturers and sellers often use consumers' lack of knowledge about metal ceilings. Many sellers will be selling a brand name but it is another inferior product, shoddy, and tampered with. Because most of the factors consumers are most concerned about ceiling materials are: brand, price, style, quality; quality is at the end! The price of aluminum coated ceilings ranges from tens to hundreds of yuan, and the price difference is very large. Therefore, it is very necessary for consumers to understand some common knowledge about aluminum buckling. What should you pay attention to when purchasing ceilings?
Recognized aluminum plate brand: All large companies produce home improvement aluminum surface has a layer of its own brand of protective film (no brand is just a layer of transparent white protective film can determine it is not brand goods or even inferior products).
Recognize brand stamp: To avoid the ceiling and keel from different manufacturers, affecting the installation accuracy. All large enterprise production of different structural shapes have self-supporting keel, and each type of home plate keel, hanging parts, square aluminum, bottom or edge will have a brand of imprinting, is the use of machine pressure wipe Can't afford it. (No embossing is likely to be a sign that vendors sell themselves to low-quality materials by small-scale processing plants because they can reduce costs.) Without brand protection film and brand imprinting, it can be quite sure that it is the product of a small-scale processing plant. . Because these two years have seen small and small processing plants in various parts of the country, prepare materials containing chromium, lead, mercury and other harmful substances for recycling scrap aluminum, (the price of such substrates is low) in the vicinity of the decoration market. Processing. Convenient for those who hung a brand name dealer, or those who do not have a brand to order.
Look at the material: It depends on the quality of the aluminum plate, not the thicker the aluminum plate, the better. Nowadays, most of the 0.8-thick aluminum plate is the inferior product produced by a small-scale processing factory. Inferior aluminum gussets are often used on aluminum substrates and aluminum gussets. Usually, the thickness of aluminum substrates is reduced, and a very thick coating is used on aluminum substrates. Even aluminum gussets on the market have only aluminum substrates. 0.43mm, there is 0.3mm coating. (Though it is 0.8 in the face of the Consumer), the excessive thickness of the aluminum buckle plate substrate will also degrade the performance of the aluminum buckle plate. Because of the low cost of this type of aluminum pinboard substrate, and this thickness can cater to the unknowing consumer psychology, it is very deceptive, and many consumers are very easy to do so. In fact, taking into account the installation span requirements of home improvement products, under the premise of using high-quality aluminum materials, experts recommend that the use of aluminum buckle plate thickness of 0.6-0.7 is enough, because this thickness of aluminum buckle plate is the best cost-effective, completely To meet the bearing strength. If the thickness is thickened, it will not only waste resources, but also increase the senseless economic burden on consumers. A good quality aluminum plate has a certain degree of hardness, elasticity, good toughness, bending to a certain degree to restore the original shape, long-term use will not be aging deformation. Fingers strike the aluminum gusset plate, and the material of the aluminum gusset plate with better material is relatively clear and crisp, and the material is relatively poor in boring, and the metal sound is not obvious.
Look at the color of the film: mainly to see the process of the film covered by the ceiling, the film is not the brighter the surface the better, the general good quality film surface is smooth and smooth, good reflective, long-term use of the surface will not change Wrinkle, discoloration. (The good film thickness is only 0.10 mm-0.15 mm)
Look at the keel: The quality of the keel is a problem many consumers ignore. The material of the keel is generally divided into aluminum, iron and non-fingerprint steel. Aluminum keels do not rust, but sales are very low because of the relatively high cost. The iron keel is easy to rust, although the keel is usually hidden behind the ceiling, but the rust is scattered on the ceiling and is not good for the ceiling. Over time, it will also affect the stability of the ceiling. The fingerprint-free steel keel is less prone to rust than the iron keel and is currently the most commonly sold item in home improvement tooling.
