Lenoir Mirror Company grinds grooves in glass for both decorative and functional purposes. Like the other fabrication processes, grooves involve abrasive grinding and, in some cases, polishing. The traditional plate or dish groove is ground parallel to the back edge of glass shelves. These are used for display purposes. Decorative grooves are ground in various patterns on glass/mirror surfaces for aesthetics. We are also capable of grinding holes in various diameters in glass/mirror. The function of the holes is for the attachment of hardware. We offer a safety tape backing (CAT II) to mirrors primarily for protection in certain installations such as sliding and bi-fold mirror doors. The tape backing is applied in an adhesive pressure process. The tape backing is tested to meet Ansi Z97 specifications. Another type of tape backing is applied for use in shower doors.
