Process for rendering a metal sheet suitable for lighting applications and sheet produced thereby

摘要: Non-directional and diffuse reflecting photometric properties may be imbued to a metal sheet stock, particularly aluminum alloy by directly creating textured surface on one or more surfaces of the stock through mechanical texturing with at least work roll in cold reducing mill. A thus produced is characterized having over its entire randomly formed imbricated depressions transversely arranged, such that each depression has substantially transverse width dimension relative longitudinal axis greater than width. The are equiaxial. Surface both controlled. subjected finishing steps as chemical brightening anodizing, organic coating provide lighting sheets high total reflectance.
