[0002] The aluminum alloy grid is a net-shaped material made of aluminum alloy, which can not only have a good decorative effect, but also participate in the stress of the structure, has a higher tensile strength and rigidity, thereby effectively resisting buckling deformation. It is usually used in the field of building for lighting, ventilation and the like. It has the characteristics of light weight, corrosion resistance, wear resistance, easy installation, etc., prolongs the service life of the grid, reduces the maintenance cost, and enhances the appearance quality.

[0003] At present, the technical conditions of domestic and foreign factories are limited, and large-section grid materials cannot be processed. It is very difficult to make and process the mold. The mold is too large, which leads to the fact that most profile manufacturers cannot process and produce, which brings great hidden troubles to the on-time supply of materials. The rod of the large-curvature grid system is too long, and the installation space is limited. For most aluminum alloy grids, aluminum square tubes are generally used, and the grid size is small. During installation, a mechanical connection method is usually used, and the top and bottom connection structures are exposed, which makes the facade effect not beautiful enough.
