Below is a list of Perforated Sheets manufacturers from Charlotte, North Carolina. Perforated sheets are planes of metal that have been punched or stamped with holes or other shapes in a pattern or in a series. While “sheet” is not a quantitative descriptive term, it is usually used in reference to comparatively thin metal planes. Perforated metal sheets are usually fairly light in weight and feature higher load-bearing capacity than wire mesh, expanded metal and other alternatives to perforated metal.
