High Speed Highway Guardrail Roll Forming Machine for Production Line High Percision

Highway Guardrail Roll Forming Machine

Description:Automatic W-beam highway guardrail roll forming machine for 310/380/420 MPa steel. CE-ready, 15–22 m/min, custom punching. Request a quote today.

Our highway guardrail roll forming machine is built for road safety barrier manufacturers that need stable, repeatable production of W-beam and thrie-beam guardrails. It decoils galvanized steel strip, pre-punches hole patterns, rolls the profile through calibrated stations, and cuts to length automatically—so your line runs continuous shifts without manual rework.

Whether you supply to highway contractors in Southeast Asia, Africa, the Middle East, or Latin America, the machine adapts to local standards (AASHTO M180, EN 1317, or client drawings) and works with 2–4 mm thickness, 310–420 MPa yield strength.

 

Why Buyers Choose This Guardrail Forming Line 

Consistent profile accuracy​ – servo/hydraulic punching and fine-adjusted roll stations keep wave height and hole position within ±1 mm, reducing on-site fitting complaints.

 

Higher line speed​ – 15–22 m/min depending on thickness; PLC set-up saves recipe memory for different guardrail sizes.

 

Lower scrap rate​ – pre-leveling + guide system prevents edge waviness; typical material waste drops vs. manual press-brake bending.

 

Easy changeover​ – spacers and cassette tools let your team switch between W-beam (two-wave) and thrie-beam (three-wave) in hours, not days.

 

Export-ready build​ – painted/anti-rust treated frame, CE-labelable electric cabinet, English/HMI panel, spare-part kit for container shipping.

 

Typical Applications 

Expressway and national road W-beam guardrail panels

 

Thrie-beam transition sections for bridge approaches

 

Galvanized steel barrier posts and rails (with separate punching dies)

 

Guardrail retrofit projects requiring mixed hole patterns

How the Production Line Works 

Hydraulic decoiler​ holds 5–10 t coil and feeds strip steadily.

 

Leveling + guide​ removes camber before forming.

 

Punching station​ makes bolt holes, beam holes, and end slots at set pitch.

 

Roll forming​ shapes the wave profile through hardened Cr12 rollers.

 

Cut-to-length​ severs panels without stopping the line.

 

Output table / auto stacker​ collects finished 4–6 m guardrail beams.

 

Compliance & Delivery 

Frame and electric design prepared for CE marking​ on request

 

ISO 9001 workshop inspection report provided

 

35–45 days production, 20GP/40GP container packing with steel skid

 

Online commissioning video + 24-month core-part warranty

 

MOQ: 1 set; OEM panel language and color available

 

FAQ

Q: Can one machine produce both W-beam and thrie-beam?

A: Yes. With exchangeable roller cassettes and adjusted punching dies, the same line covers two-wave and three-wave profiles.

Q: What coil thickness is most common?

A: Export projects usually run 2.5–3.0 mm galvanized steel for W-beam; thrie-beam often uses 3.0–4.0 mm.

Q: Do you supply guardrail post machines together?

A: We can bundle a C/U post roll former and guardrail line as a full barrier production plant.

Q: How long to change guardrail length recipe?

A: Operator inputs target length and hole pitch in the PLC; tool change takes 2–4 hours with two technicians.
