I. Product Introduction

This machine is professional equipment for producing highway two-wave and three-wave guardrail plates.

Key capabilities:

• Processes galvanized steel coil and color-coated steel coil into standard road safety guardrail profiles through continuous cold bending forming.

• Widely used in highways, municipal roads, bridges, and mountain road safety barrier construction.

• Produces guardrails of different specifications.

• Fully automatic operation with stable performance.

• Core production equipment for road safety facilities manufacturers.

II. Key Features and Advantages

1. Heavy-Duty, Reinforced Frame for Durability

• Welded frame made of thickened steel plates meeting national standards.

• Annealed to resist pressure and vibration.

• Vibration-free and distortion-free during prolonged continuous operation, ensuring long service life.

2. High-Quality Rollers for Superior Forming Results

• Made of high-quality alloy steel, treated with high-frequency quenching and precision turning/polishing.

• High surface hardness, excellent wear resistance.

• Produces smooth curves, precise dimensions, and scratch-free surfaces.

• Ensures high assembly fit of guardrail panels.

3. Fully Automatic Computer Control System

• PLC-based CNC control cabinet with touchscreen operation.

• Automatic length setting, counting, and hydraulic cutting.

• One-button parameter setup, easy for unskilled operators, reducing labor costs.

4. Fast Production Speed and High Output

• Continuous feeding and forming at uniform speed without deviation.

• High daily output, suitable for large-scale, high-volume production.

5. Wide Range of Compatible Raw Materials

• Processes cold-rolled steel, hot-dip galvanized strips, black steel, and color-coated strips.

• Sheet thickness adjustable for standard and non-standard guardrail panels.

6. Stable Operation and Extremely Low Failure Rate

• Dual-drive structure combining chains and gears.

• Powerful transmission with low operating noise and minimal vibration.

• Uses standard components for simple repairs and low maintenance costs.

7. Customizable Designs

• Custom two-wave, three-wave, and reinforced guardrails.

• Wave height, width, and thickness adjustable to meet different national standards and construction site requirements.

III. Strict Quality Inspection Process Before Shipment

1. Raw Material Inspection

• All frame steel plates, rollers, spindles, motors, and electrical components inspected upon warehouse arrival.

• Non-conforming materials are rejected.

2. Machining Precision Inspection

• Spindles, forming wheels, and drive shafts precision-ground and calibrated for concentricity and parallelism.

3. Complete Machine Assembly and Commissioning

• 2–4 hour no-load test run to verify smooth transmission, rotation, and lifting operation.

4. Production Run with Material

• Tested with actual color-coated steel sheets in continuous production.

• Verifies dimensions, flatness, and neatness of cut edges.

5. Comprehensive Electrical and Control System Inspection

• Ensures CNC system, counter, cutting system, and emergency stop function properly.

6. Final Factory Acceptance

• Checks for cleanliness, complete accessories, and documentation before shipment.
