Abstract of the Disclosure A process for making an insulated metal edge guard comprises extruding plastic insulating metal material onto a flat strip of metal as the strip is pulled through an extruder, coiling the insulated strip while still in the flat, uncoiling the coiled strip at the beginning of a roll-forming apparatus and feeding the insulated strip through the roll-forming apparatus to form the strip into a desired cross sectional shape for the edge guard. The process improves the efficiency of manufacturing insulated metal edge guards and it permits various embodiments, in- cluding new and unique ones, to be created efficiently. The invention has a special utility where a range of colored edge guards must be produced in varying quantities. 21
