3-4mm Heavy Steel U Post Roll Forming Machine With Inline Punching And Stop Cut System

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

• A dedicated roll forming solution designed for highway infrastructure manufacturers, offering automation, high-precision punching, and strong steel profile forming for 3–4mm U posts.

2. Profile Description

• Cold-rolled galvanized steel U post, 3–4mm thick, with top flanges and slotted holes, designed for anchoring guardrails. Features strong impact resistance, standardized hole positions, and applications in road safety.

3. Production Process

• 5T Hydraulic Decoiler → Feeder & Guide → Leveling Machine → Hydraulic Punching → Guiding Device → Roll Former → Stop Shear Cutting → Out Table

• The production begins with heavy coil feeding aided by a motorized head feeder. After leveling, high-speed hydraulic punching creates mounting holes before roll forming. Stop-cutting ensures no material waste.

5. Key Focus

• Hydraulic head-feeder ensures smooth entry for thick steel coils.
• Punching and forming machine share one base for better alignment.
• Hole positions align with installation points for efficient post-assembly.
• Stop-cutting avoids scrap and improves material utilization.
• Integrated gearbox drive ensures stability in thick material forming.
