Full Automatic Galvanized Steel Door Frame Cold Roll Forming
Steel door frame roll forming machine can make various types metal
door or window frames, reinforced, fire stop doors, etc by roll
forming method. The steel door frame roll forming machine is a
complete production line. After roll forming by our production
line, we could make very smooth and beautiful steel door frame
without any scratch on surface. This steel door frame production
line is composed by the following elements: De-coiler, feeding
& leveling device, main roll forming machine, cutter, run-out
table, etc. Those machines are customized according to the drawing
