DUWELL can make the guardrail post machine, including C profile post, U profile post or Sigma profile post. The machine is suitable for high strength steel, with a minimum yield strength 345Mpa and material thickness 4.0~6.0mm. Various countries use different sections of different shapes for columns. We can make the roll forming machine according to customer’s required post shape or samples.
Uncoiler: Loading the steel coil
Leveling : Leveling the sheet flat before entering pressing machine
Servo feeder and hydraulic punching device: Punch the holes on the sheet before forming.
Profiling Roll Forming Machine: For precise profile forming.
Hydraulic cutting device: Cut off the rails according to setting length.
Adjusting device: For final straight adjusting.
Stacking Table: Stacking the finished rails.
