Our warning (caution) foils are made from PE (polyethylene) by extrusion technology. They are produced in various coloured designs, with single- or double-sided pattern, with micro-perforations or without perforation. They serve to highlight and warn about the existence of cable routes and other conduits embedded in ground foundations, etc. These foils do not provide mechanical protection of such networks.
