The metal sheets are joined by welding to create a robust composite structure. The sheets are then subjected to a grinding stage to eliminate surface imperfections, improving the overall finish. The production line aims to produce high-quality welded metal sheets without defects, suitable for applications requiring both strength and refined appearance. A vacuum mechanism is used to perform the rotations, allowing for rotation up to 180 degrees. This technology allows safe lifting, transporting, and positioning of sheet metal using a crane equipped with a vacuum attachment. The vacuum creates a suction force that securely holds the sheet metal during lifting and moving, preventing slipping and damage. The combination of welding, grinding, and turning ensures that the finished products meet strict standards of structural integrity and aesthetics.
