Laminated stainless steel shim is made from an annealed 300 series stainless. Composition 3, type 1, class 1. Fully laminated. Peel off layers to needed thickness. Allows more on-site accuracy. Precision Brand® laminated shim is made by using pressure and resin/adhesive to bond metal shim together which creates a rigid "1-piece" item that appears to function as a single solid metal sheet or plate. Remove layers by peeling away with a pocket knife to the desired thickness. Sheets may be cut, sawed, stamped, milled or bored to almost any configuration. Bonding adhesive makes for just right peeling, no tearing or ripping of the layers. Sheets are uniform from edge to edge.
