Heavy-Duty W Beam Roll Forming Machine With Hydraulic Pre-Cutting And Gearbox Drive

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 manufacturers in the road safety industry seeking high-precision, heavy-duty W beam guardrails using 3–4mm steel.

2. Profile Description

• W-beam guardrails are made from 3–4mm galvanized steel. Their corrugated shape offers high impact absorption and structural strength, widely used in highways for vehicle collision protection.

3. Production Process

• Manual Decoiler → Feeding Guide → Leveling Machine → Hydraulic Punching → Pre-cutting Unit → Roll Former → Hydraulic Cutter

• The process includes decoiling and guiding thick steel coils, flattening via a stand-alone leveler, hydraulic multi-station punching, precise pre-cutting, 28-pass forming by gear-box-driven roll former, and final hydraulic cutting for finished guardrail lengths.
