product description

1. Product Overview

This highway guardrail roll forming machine is a professional cold roll forming equipment specially designed for mass production of highway W-beam guardrails and three-wave guardrails. Adopting advanced continuous cold bending molding technology, the machine can process galvanized steel coils into standard road safety crash barrier profiles in one continuous process, including automatic feeding, leveling, punching, roll forming, hydraulic cutting and finished product output.

Compared with traditional scattered processing equipment, our highway guardrail roll forming machine integrates all production procedures into one unit, greatly saving factory space, reducing labor costs and improving overall production efficiency. The finished guardrails produced by this machine feature uniform curvature, accurate hole positions, smooth surface and strong anti-collision performance, which fully meet national and international highway safety construction standards.

2. Main Structure & Working Principle

The whole set of highway guardrail roll forming machine consists of 7 core components:

1. Automatic Decoiler: Supports 3-5 tons raw steel coil loading, stable feeding without material deviation;
2. Leveling Device: Eliminates steel plate bending deformation to guarantee flat raw material before forming;
3. Hydraulic Punching Station: Precisely punches mounting holes on guardrails at fixed spacing, hole size & position adjustable according to customer drawing;
4. Roll Forming Host: Multi-group heavy-duty forming rollers made of high-strength Cr12MoV alloy steel, durable long service life, stable molding without plate distortion;
5. Chain Transmission System: Thickened industrial roller chain drives each forming group synchronously, low noise and stable operation;
6. Hydraulic Cutting Unit: Fast hydraulic shear cuts guardrails to customized fixed length without burrs on cutting edges;
7. PLC Control Cabinet: Full automatic PLC touch screen control, one-click set production length, punching interval and running speed, easy operation for workers.

Working flow: Steel coil feeding → plate leveling → automatic hole punching → continuous cold roll forming → fixed-length hydraulic cutting → finished highway guardrail output.

3. Core Advantages of Our Highway Guardrail Roll Forming Machine

✅ High Production Efficiency The running speed of this highway guardrail roll forming machine can reach 10-18 meters per minute, capable of producing hundreds of guardrail pieces per hour, fully meeting large-scale road engineering order demands.

✅ High Forming Precision All forming rollers are CNC machined with precise dimensional tolerance. The finished W-beam guardrail has consistent wave depth, flat surface and accurate punching position, no secondary trimming required.

✅ Heavy Duty & Long Service Life Main frame adopts thickened steel plate welded structure, anti-deformation under long-time heavy load. Forming rollers are quenched and tempered, wear-resistant, service life over 10 years under normal maintenance.

✅ Fully Automatic Intelligent Control Equipped with Siemens PLC and touch screen, all parameters like product length, punching distance, running speed can be set digitally. Automatic alarm system for material shortage, overload and fault problems, convenient maintenance.

✅ Multi-Model Compatibility One highway guardrail roll forming machine can be customized to produce 2-wave guardrail, 3-wave guardrail, bridge guardrail and other road barrier profiles, only need to replace forming rollers to switch product specifications.

✅ Stable Hydraulic & Transmission System Adopts international standard hydraulic components, stable punching and cutting pressure; thickened double-row chain synchronous transmission ensures no material slipping during high-speed forming.
