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.
