Does anyone know what sort of temperatures bull wire will take before it starts to stretch and melt? By bull wire I mean specifically the wire used to hold up suspended ceilings as you would have in office buildings and the like.
If it is steel wire it will start to stretch around 1,000 deg C and melt at 1200 to 1400 C exact temp depends on the grade of steel but it is well over the temp at which combustable materials will catch fire and burn. In over words the ceiling will have burnt down long before the wire melts.
