1. Sheet metal processing
This process is mainly through the flat plate after cutting, folding, bending, welding, grinding and other processes, the aluminum plate into the construction of the required shape and size.
2. Spray coating
Spraying is to spray paint on the finished sheet metal. Spraying is divided into two types, one is manual spraying and the other is machine spraying. Machine spraying is generally only suitable for regular slabs, but this kind of aluminum veneer is used less in actual use, and most domestic manufacturers use manual spraying.
3. Processing and forming
Aluminium plate curtain wall processing adopts high-quality high-strength aluminum alloy plate, its common thickness is 1.5, 2.0, 2.5, 3.0 MM, model 3003, and the state is H24. The maximum size of conventional materials is 1220mm×2440MM. Its structure is mainly composed of panels, ribs and corners. The corners can be bent or stamped directly from the panel, or corners can be riveted on the small edge of the panel. The ribs are connected to the welding screws behind the board to make it a solid whole.
