From the specification aluminum veneer is divided into two types: the thickness of 1.2mm or less in aluminum veneer called Lvkou (also called aluminum square plate), thickness of 1.5mm or more of aluminum called aluminum veneer veneer. Aluminum curtain wall veneer of high quality high-strength aluminum alloy sheet, its thickness commonly 1.5,2.0,2.5,3.0MM, model 3003, the status of H24. Its structure consists of panels, stiffeners and angle code components. Corner directly, press molding by a panel bending, but also in small panel edge Corner shaping riveting. Welded screw ribs and the board after (the screws are welded directly in the back of the board) connections, making it a solid overall, greatly enhances the strength and rigidity of the aluminum curtain wall veneer, to ensure the long-term use of the flat degrees and wind and seismic capacity. If you need noise insulation, install efficient noise insulation material on the inside of an aluminum plate. Modeling ceiling Non-standard board: 1, is expected to open: the sheet by drawing good start to expand the size of the material; 2, Cutaway: A good start by folding the sheet material highly cut and angle; 3, forming: by bending molding machine according to the drawings FIG folding and forming; 4, Welding: the four corners of the plate forming a good weld; 5, put the ribs: required in the back plate mounted aluminum bars, in order to strengthen stability and surface smoothness; 6, polishing: the spraying the surface of polished fine and welding mouth polished smooth; 7, Inspection: according to the drawing size and corporate standards or line marked inspection; 8, pre-treatment: the qualified products to lay the technology holes for hanging, then surface chromium treatment; 9, spraying: the processing sector put good spray coating line, to ensure consistent color without color, smooth surface without flow marks; 10. Packing: qualified products affixed with a protective film, and then the paper or foam skin plastic wrap.
