Exothermic burning bar economically cuts heavy ferrous and non-ferrous scrap at 7,000+ degrees F. Bars are made from 16 ga. electric welded tubing (0.065" wall) filled with proprietary wires that sustain their own flame and high temperature after lighting. Requires use with bar holder and Personal Protective Equipment (PPE). The bar is 10 ft. long x 0.675" diameter and will burn for approximately 6 minutes. This is a plain end bar. Bars ship in bundles of 100 via van trailer or flatbed depending upon order quantity.
