2019 New Style Pop Channel Roll Forming Machine - Highway Guardrail Roll Forming Machine – Xinnuo

*Detail


Xinnuo highway guardrail roll forming machine is comprised of roll former unit, press. decoiler, receiving rack, and computer control system. It is designed especially to produce highway guard rail, which works to transfer the impact energy through the deformation of column and beam, to force the out-of-control vehicle to go back to its original direction, and to protect the vehicles and passengers to the max extent.
