The aluminum composite panel is composed of a variety of materials, one of which is an aluminum composite sheet. Aluminum composite sheet is mainly used for exterior wall decoration. Some people call it embossed aluminum sheet. There are many types of alloys. Aluminum composite sheet can be 1100 aluminum sheet, 1050 aluminum sheet, 1060 aluminum sheet, 3003 aluminum sheet, 3005 aluminum sheet, 5005 aluminum sheet and so on. Regarding the thickness, 1100 aluminum sheets with a thickness of 2-4mm or 3003 aluminum sheets with a thickness of 2.5mm are generally used. The specific choice of alloy type depends on your end use. Aluminum composite sheet generally adopts 3-4mm three-layer structure, including two 0.5mm sandwich PVC or PE. It can be seen from the materials that its cost is definitely higher than that of ordinary aluminum sheets. But don't worry, if you don't have any requirements for functions and features, then 1000 series aluminum sheet is the most suitable, because its price is the lowest compared to other series.
Introducing aluminum composite sheet color coating. At present, the commonly used color coating methods include fluorocarbon spraying and roller coating. Let's talk about spraying first.
There are two main steps for spraying:
One is the processing of aluminum sheets. The processing process can be divided into the following steps: cutting, folding, bending, welding, and polishing. The purpose is to process the aluminum panel into the shape and size required for construction.
The second is spraying. After the processed sheet metal of step 1, paint is sprayed on it. Spraying can also be divided into two types, one is manual spraying and the other is machine spraying. Machine spraying is not suitable for all types, only for regular flat panels, but this kind of aluminum panel is rarely used in actual use.
There are some steps in the processing of aluminum composite sheet. There are mainly four major processes: chemical conversion, coating, compounding and trimming. These four processes are all automated production except for trimming. It can be seen from the processing process that this material has certain advantages in environmental protection and safety.
The structure of aluminum composite sheet determines its purpose. The upper and lower layers are relatively thinner and coated with decorative paint, and then composited with plastic or other materials in the middle. The building materials we usually see are made in this way. Aluminum composite sheet has a wide range of uses. It can be used on the exterior walls of buildings, and can also be used in some advertising signs and other places. Building decoration materials are its most common application, and it is also its most typical use.
