Comparison Of Aluminum Veneer And Aluminum Composite Panel(1)

The application of metal panel curtain wall has a history of decades, and now there are three types of Acp Aluminium Sheet, Aluminum Composite Panel For Sale and Aluminum Honeycomb Panel. Among these three materials, the most commonly used are aluminum veneer and aluminum-plastic panel. Aluminum veneer was the first to appear. Later, in the late 1960s and early 1970s, Aluminium Honeycomb Composite Panel were invented in Germany and quickly became popular all over the world. What is the difference between Aluminum Composite Panel Home Depot and aluminum veneer? Here I will make a simple comparison of these two materials:

1. Material and cost Aluminum veneer generally adopts 2-4mm thick AA1100 pure aluminum plate or AA3003 aluminum alloy plate. In China, 2.5mm thick AA3003 aluminum alloy plate is generally used; aluminum-plastic composite plate generally adopts 3-4mm three-layer structure. Including two upper and lower 0.5mm sandwiched PVC or PE. We can see from the materials that the cost of aluminum-plastic composite panels is definitely much lower than that of aluminum single panels. The current market is about 4mm thick Aluminium Composite Panel Sheet are more than 120 yuan/square lower than 2.5mm thick composite panels. For a 10,000 square project, the use of aluminum composite panels will reduce the cost of 1.2 million yuan compared with aluminum veneers. .

2. Processing process

There are currently two types of aluminum veneers in the world: fluorocarbon sprayed aluminum veneers and roll coating. There is no stick coating production line in China for the time being, so the veneer processing process here is mainly about fluorocarbon spraying production. Spraying production of aluminum veneer is divided into two major steps: the first step is sheet metal processing. This process is mainly to process the aluminum veneer into the shape and size required for construction by cutting, folding, arcing, welding, and polishing the flat plate. The second step is spraying. Spraying is spraying paint on the processed sheet metal. There are two types of spraying, one is manual spraying and the other is machine spraying. Machine spraying is generally only suitable for regular flat plates, but this type of aluminum veneer is rarely used in actual use, and most domestic manufacturers use manual spraying. Manual spraying is a dangerous job, because paint is relatively volatile and toxic, and it is easy to cause chronic benzene poisoning, which seriously affects human health. A major advantage of manual spraying is that the color can be chosen regardless of the amount, while the roll coating of aluminum-plastic panels must reach a certain amount before processing. The processing process of Alucobond Acp Sheet is more complicated than that of aluminum veneer. There are four major processes: forming, coating, compounding and trimming. These four processes are all automated production except for trimming. It can be seen from the processing process that aluminum-plastic panels have certain advantages in environmental protection and safety. Coupled with the simplicity of the sheet metal processing of aluminum veneers, some private workshops have also begun to get involved, which has seriously affected the stability of the market quality of aluminum veneers.

3. Product appearance quality and physical properties items 2.5mm aluminum veneer 4mm thick aluminum-plastic composite panel appearance quality The flatness of the flat plate is not high, it looks like there are local unevenness, the flatness of the flat plate is relatively high, but the processing shape is limited; but Brushed Aluminium Composite Sheet can be processed into various irregular shapes; the spray roller coating has good visual quality, and the color difference and film thickness deviation are not obvious due to the instability of artificial technology, but the damage cannot be repaired locally. Deviation from film thickness; local damage can be repaired. Tensile strength 130/mm 38-61N/mm2X Elongation 5%-10% 12%-17%.Bending strength 84.2N/mm 34N/mm2 Elastic modulus 70.00N/mm2 26.136-49.050N/mm2 can be from the table It can be seen that the appearance of aluminum veneer is a little worse than that of aluminum composite panel, but its mechanical properties are significantly better than that of aluminum composite panel, and its wind resistance performance is also better than that of aluminum composite panel. However, in most areas of our country, the wind pressure value of Plastic Aluminium Composite Panel is completely bearable. Therefore, the use of aluminum veneers in projects is a bit overkill.
