The two-beam and thrie-beam guardrails are one of the main components of the road anti-collision guardrails. One machine can make the two wave and three wave plate shapes, and only need to replace 3 moldings. The speed of this machine is fast, and it can produce three kinds of products with punching holes in one minute. The whole production line adopts servo motor, which makes the machine more precise and more efficient.

The main process route is: uncoiling-leveling-servo feeding-on-line punching (end and reinforcement holes)-cold roll forming-tracking cutting-automatic coding
