Aluminum composite panel is essentially a structure or a panel made up of two flat aluminum panels. Normally, two flat aluminum panels held together tightly with a non-aluminum core to make it lightweight, durable and compact in features. It is made from low-density polyethylene.Aluminum composite panels come in different shapes and sizes to meet various industry needs. However, the standard size A2 core coil production line is the four millimeters panel. It is made up of 3-millimeter core and ½ millimeter aluminum exterior.The layers can be divided into two distinct categories. The first one is the internal layer which is basically the core of the entire structure. The second one is the external layer.Unlike the common type metal sheets, the Aluminium composite panels are lightweight, extremely durable and lightweight. This is why people like to use these to make different types of stronger structures quickly. These are very easy to install.
