15m/min High Precision W Panel Roll Guardrail Forming Machine For 3–4mm Galvanized Steel

High Precision W Panel Roll Forming Machine for 3–4mm Galvanized Steel

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 roll forming line is designed for highway guardrail manufacturers and metal profile suppliers in the road safety sector. It provides stable, high-precision W-beam production for heavy-duty applications. Ideal for companies seeking long-term performance, flexibility in thickness, and consistent panel quality using cold-rolled galvanized steel.

2. Profile Description

• The W-beam guardrail profile is made from 3–4mm thick galvanized steel, with a two-wave curved structure. It offers high tensile strength, corrosion resistance, and is widely used for highway crash protection. The profile’s punching design ensures easy installation with bolts and posts on roads and bridges.

3. Production Process

• 7.5T Hydraulic Decoiler → Guiding Device → Powered Roller → Leveling Machine → Hydraulic Punching → Roll Former → Hydraulic Stop-to-Cut Cutter → Output Table

• The line begins with coil decoiling, guiding, and assisted feeding via powered rollers. Leveling and punching share the same base with the roll former, optimizing space and alignment. Punching uses dual stations for efficient hole layout. The 18-station gearbox-driven roll former ensures high precision, ending with a hydraulic shear.
