COILS/STRIPS

La.Met manufactures a comprehensive range of silver coils/strips for a wide variety of applications (stamping, continuous cutting, continuous laser-cutting, photo-frames etc) and flat-wire for chains. The strip surface is bright and defect-free. The compact grain-structure guarantees excellent results even for the most complicated of mechnical deforming operations. Strips have a clean cut-edge and are wound perfectly with various internal diameters.
