High-Speed Cold Roll Forming Line for W Panel Highway Guardrails with Hydraulic Punching and Magnetic Stacking

These introductions refer only to the production line and configuration shown in the main image. Each machine is custom-built. Metalign welcomes your inquiry and provides the right production line—forming metal into profiles aligned to your needs.

1. Production Line Overview

• This production line is tailored for the production of W panel guardrails, commonly used in highway safety.

• The line offers fast production with high-quality forming, punching, and automated stacking. It’s ideal for road construction contractors and infrastructure projects needing heavy-duty, reliable guardrails.

2. Profile Description

• The W panel is constructed from 3-4mm cold-rolled steel, often galvanized for enhanced corrosion resistance. Its wave-like profile is designed to withstand high-impact forces.

• These panels are typically used in highway barriers, offering reliable vehicle impact protection. They feature precision holes for mounting and alignment in guardrail systems.

  The steel coil is fed through a decoiler and aligned by guiding rollers. It is then leveled for a smooth finish. The material undergoes precise hydraulic punching for hole formation before being cut to length. Afterward, the transfer conveyor moves the material to the roll former, where it is shaped into W panels. Finally, panels are safely stacked with a magnetic stacker for efficient handling.
