Freeway Crash Barrier Roll Forming Machine 25m Every Min Front Hydraulic

Product Specification

Highway guardrail/cold roll forming machine with 25m/min forming speed

Description of the machine:

Adopt advanced automatic control software achieving information management for production. We roller on each piece of machine is the use of 45# steel Qenched for each roller, the roller increases the hardness and long service life. And the use of plating technology roller surface treatment to improve the equipment of the main performance. The sliding table of cutting device adopts hydraulic control. It is adjustableand reliable.The quality of the production of guardrail, compression and seismic resistance, high hardness, is the protection of the highway barrier, people's safety has been guaranteed.
