LIXIN® multi-wall hollow sheet is a reinforced sheet that adds diagonal support on the basis of the rectangular section of the hollow sheet to improve the overall pressure-bearing capacity of the sheet. This kind of sheet can support larger purlin spacing, reduce the amount of installation profile used, so that the designer can have more room to play when selecting materials. The increased diagonal support effectively enhances the lateral stability of the sheet, making the main structure more reasonable. The cavity formed by the multi-layer structure increases the thermal insulation performance, and has a lower U value than ordinary sheets of the same thickness. LIXIN provides a variety of hollow structures, and can optionally add multiple functions such as infrared light control, UV matte surface, anti-drip, and easy-to-clean. It has a wide range of applications and is a light-weight and high-intensity lighting solution.
