Highway Guardrail Roll Forming Machine

What Is A Guardrail

Guardrail or Guard rail is a protection system that prevents vehicles from entering dangerous areas of expressways. The thickness of the guardrail can reach 4.0mm.

It mainly used for highway, large parking areas, the scenic areas, provincial roads, rural roads, and other anti-collision safety engineering construction.


Types of Guardrail

The most common type of guardrail is W-shaped steel beams, also called two-wave guardrails. Now, The Beam guardrail is a new trend, which is similar to forming two W-Beam guardrails into one new guardrail.


Crash barrier or Guardrail is an obstacle designed to prevent the vehicle from deviating from a safe road to improve the safety of the driver. Zhongyuan automatic guardrail roll forming machine can produce 2 wave guardrails or 3 wave guardrails according to customer requirements.


Our experienced engineers are ready to design your high-efficiency roll formers to produce w beam guardrails, the beam guardrails, and other road safety barriers.


Steel Guardrail Roll Forming Machine

The guardrail surface produced by the highway guardrail forming machine is clean, flat, corrosion-resistant, anti-aging, and resistant to high and low temperatures. Under normal circumstances, the service life can reach 10-25 years in the outdoor environment;

• Leveling roller: Upper layer 4 rollers, down layer 5 rollers, totally 9 rollers

• Leveling roller material: 45# steel, thermal treatment hardness 48-52 HRC

• Leveling shaft material: 45# steel, ¢76mm, hardening and tempering


Punching Device for Guardrail Forming Machine (Option)

The punch material is CR12 and the hardness is HRC58-62. It uses high-speed molds and uses different station molds to punch different holes (without changing molds). The die adopts a unit structure design, and the die is adjustable. It has a long service life and is easy to replace and maintain.

• Mould material: Cr12, quenched 58°C-62°C

• Power of hydraulic station:11KW


Forming Device of Highway Guardrail Roll Forming Machine

All rollers are made of CR12 material, heat treatment, HRC 58-60. They are processed by CNC processing to ensure that the rollers have good rigidity and precision, and form a perfect guardrail according to the design.

• Thickness range: 2.5-3.2mm

• Production line length: 11m

• Forming speed: Not less than 15m/min

• Main motor power: 5.5X3kw

• Shaft diameter: 90mm

• Roll station:15 stations

• Transmission: By gearbox 

• Roller Material: CR12, HRC58-62, CNC processing after heat treatment.


Cutting Device of Guardrail Roll Forming Machine

Advanced hydraulic drive, PLC control automatic cutting. Automatic punching and cutting after forming, no deformation.

• Cutting type: Hydraulic cutting
