The material of the aluminum gusset material and the method to identify the quality!

        After more than ten years of development, the material of aluminum gusset board is constantly updated, and the first generation product is gypsum board and mineral wool board; the second generation product is PVC; the third generation product is metal ceiling. Among the metal ceilings, aluminum gussets come in behind and emerge as a new force. At present, the aluminum gussets on the market are also divided into the following grades: the first type of aluminum-magnesium alloys also contain part of manganese. The biggest advantage of this material is that it has good oxidation resistance. At the same time, due to the addition of an appropriate amount of manganese, the strength and stiffness have been improved, and it is the best material for the ceiling; The second type of aluminum-manganese alloy, the strength and stiffness of the plate are slightly better than that of the aluminum-magnesium alloy, but the oxidation resistance is slightly insufficient; the third type of aluminum alloy, the plate contains less manganese and magnesium, so its strength and stiffness are obvious It is lower than aluminum-magnesium alloy and aluminum-manganese alloy, and its anti-oxidation ability is general.
        The key to choosing an aluminum gusset is not its thickness, but the material used. A household plate of 0.6MM is enough, because the aluminum gusset does not have the same span problem as the plastic plate. The key to the choice is the elasticity and toughness of the board, followed by the surface treatment. .
        At present, many merchants use the thickness of the gusset as a reason to sell high prices, and consumers are convinced of this. As everyone knows, the quality of the aluminum gusset has nothing to do with the thickness, but completely depends on the material. Since inferior aluminum gussets cannot be made thin, they are easy to corrode and peel off, which greatly affects future use. Therefore, the first step in purchasing an integrated ceiling is to know the material of the gusset plate.
        A. Laminated board: Generally, the national standard aluminum is used. The board is treated with anti-oxidation, and the surface is treated with imported peritoneal membrane. It has many colors and effects. This type of board is the most common and most popular on the market, and its sales price is also According to the grade of each brand and the substrate used, it is difficult for non-general professionals to distinguish.
        B. Roller coated board: The price per square meter of the national standard product is tens of higher than that of the peritoneal board. The basic contrast characteristics are roughly the same as the film coated board, and the base material is the same, but the board surface has been repeatedly treated with high temperature baking paint and anti-oxidation technology. Finally polished. Generally, single-color products are more effective, and there are also some brands of bright color panels that are processed by roller-coated finished panels (spray paint and color printing).
        C. Anodized plate: It is the legendary brushed aluminum, and the plates are made of high-quality alloy base aluminum containing aluminum and manganese. Generally, the silver products of the base material can also be imported color board modeling boards processed by the anti-oxidation technology of baking paint. Such products have high-quality features such as wear resistance, fouling resistance, corrosion resistance and high temperature resistance, and are also commonly used substrate aluminum for mid-to-high-end products. , There are also many categories of products: anti-scratch series, nano-plate series, anti-fouling series, etc. High-end products of this material are generally difficult to oxidize and discolor after 30 years of normal use.
        D. Imported titanium alloy: The base material aluminum adopts imported titanium alloy plate which is often used in manufacturing aircraft and aviation high-end equipment technology. (The production process is cost-effective in production technology, so few brands generally use this material), the double-sided gusset plate has been finely plated and brushed, and its hand-feeling, visual texture, texture strength and 0.5 international standard thickness are beyond the reach of ordinary materials. reflect. The general product price is above 600/square, so there is no need to worry about its quality.
        There are two main points to see if an aluminum gusset is good or bad. 1. The texture of the aluminum gusset and 2. The quality of the cladding. How about the texture? Bend the board a big bend to see if there are any cracks in the middle of the board. 2. Looking at the lamination, the lamination is divided into imported and domestic ones. Most of the laminations have high brightness and can maintain 25-30 years without fading and molting. Domestically produced ones generally fade within a few years.
        Tell everyone clearly that 0.6mm is enough. Take a well-known imported brand aluminum gusset plate as an example, its price is more than 300 yuan per square meter, but what is its thickness? 0.5 mm, which is not as good as 0.6 mm! Why, the quality of the board is not good or bad It's the thickness, it's the base material. In fact, if the aluminum gusset you are consulting is a famous brand, most of them are 0.6 mm in the mid-range.
        As for why some brands of 0.8 mm are not good, and some miscellaneous brands use aluminum from cans, because of the quality of the aluminum itself, it is impossible for them to make the aluminum gusset very thin, because Aluminum is not good, and there is no way to evenly thin the board, so they can only make it thicker, and make the peritoneum thinner while the cost remains the same.

    Therefore, in order to identify the aluminum gusset, in addition to paying attention to the surface finish, it is also necessary to observe whether the thickness of the board is uniform. Pinch the board with your hand to feel whether the elasticity and toughness are good.
