Fully Automatic Highway Guardrail Rolling Forming Machine

Two Wave and Three Wave Guardrail By One Machine Rolling Forming Machine

Introduction: Precision Engineering for Road Safety

Our Highway Guardrail Roll Forming Machine​ is engineered to produce high-strength W-Beam (Two-Wave) and Thrie-Beam (Three-Wave) crash barriers according to international standards, including AASHTO M180, EN 1317, and JT/T 281. Designed for high-volume production, this fully automatic line transforms galvanized steel coils into perfectly shaped guardrails with consistent accuracy. It is the ideal solution for road safety contractors, steel mills, and infrastructure manufacturers worldwide.

Key Features & Benefits

Dual Profile Capability:Easily switch between Two-Wave (310mm)​ and Three-Wave (506mm)​ profiles by adjusting spacers or replacing specific roller stations. (Optional feature based on model).

Integrated Hydraulic Punching:Equipped with a hydraulic punching system to create bolt holes (blockout holes) and splicer holes simultaneously during the forming process, ensuring precise hole alignment.

Heavy-Duty Construction:The machine base is constructed from high-tensile steel plates, stress-relieved to prevent deformation, ensuring longevity even under 24/7 operation.

High-Grade Rollers:Rollers are made from GCr15 bearing steel, CNC machined, heat-treated (HRC 58-62), and hard chrome-plated to resist wear and protect the zinc coating of the material.

Smart PLC Control:Utilizes a Siemens/Mitsubishi/Delta PLC with a user-friendly touchscreen interface. Operators can set production length, quantity, and punching positions easily.

Technical Specifications

(Note: Specifications can be customized based on your local standards and requirements.)

Production Process Flow

Decoiling:​ Hydraulic Uncoiler holds the steel coil (Max 10 Tons).

Leveling:​ 7-roller leveling device flattens the coil entry.

Punching:​ Hydraulic punching unit creates holes according to AASHTO/JT/T patterns.

롤 포밍:​ The strip passes through multiple roller stations to form the W or Thrie shape gradually.

자르기:​ Hydraulic flying shear cuts the profile to the exact length required.

Runout:​ Finished guardrail panels slide onto a runout table or stacking system.

Frequently Asked Questions (FAQ)

Q1: Can one machine produce both 2-wave and 3-wave guardrails?

A: Yes, our semi-combinational models allow you to produce both profiles. Usually, the 3-wave requires a wider base and specific roller sets, while the 2-wave uses the same line with adjusted spacers. We can design a dedicated combinational line based on your budget.

Q2: What is the difference between AASHTO M180 and Chinese JT/T standard machines?

A: The main differences lie in the width (12″ vs 310mm), thickness gauge, and hole punching patterns. Our engineers will confirm your target market standard before production to ensure compliance.

Q3: How long does it take to install the machine overseas?

A: Typically, our engineer will complete the mechanical installation and commissioning within 7-10 days, followed by 3-5 days of operational training for your staff.

Q4: Do you provide the steel coils as well?

A: We specialize in the machinery, but we have long-term partners for galvanized steel coils and can help you source materials if needed.
