Product Details

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.


4. Technical Parameters

MachineAnalysis
Hydraulic DecoilerHolds and feeds heavy 3–4mm coils (up to 5T).
Includes pressing arm to avoid coil bouncing.
Head-Type FeederProvides extra force to push thick steel forward.
Prevents steel buckling at coil start.
LevelerFlattens steel for consistent punching and forming.
Built with forming base to ensure alignment.
Hydraulic PunchingOne large, one small station to punch holes before forming.
Shares base with roll former, keeps hole accuracy.
Guiding DeviceAligns material into forming section smoothly.
Roll FormerGearbox-driven for high torque and stability.
Form U shape with side flanges for guardrail post.
Stop Shear CutterCuts to length without producing scrap.
Controlled by encoder for precise cut length.
Out TableCollects formed and cut profiles.

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.
