Highway Guardrail Roll Forming Line

Highway Guardrail also called Road Barriers, it plays a vital role in expressway system.
Brother Union Machinery has a complete solution to produce roll fomring lines for highway safety guardrails. The continuous road barrier consists of corrugated guide rail, Distance Spacer and Post.
Our experienced engineers are ready to design your high-efficiency roll formers to produce w-beam, thrie-beam and other road safety barriers.
By quick-plugs, machine can be installed and start in shorter time to start the production.

Roll Forming Machine for Guard Rails

The crash barrier roll forming line produces two-beam and thrie-beam guardrails in one production line by interchangeable cassettes.

This guardrail line consists of uncoiler, leveling machine, servo-feeding machine, hydraulic press of hole-punching and pre-shearing, roll former and automatic finished products stacker with side transport conveyor.

The uncoiling machine with a pit-type coil car is fitted to large quantity production without down-time waiting for new coil loading.

The electrical control steel coil peeler help the operator to feed the thick steel coil into the production line easily.

The shear and butt welding device help operator to joint the steel coil end in shortest time,  short the down-time, increase the production efficiency.

The hydraulic press punches the holes on the guardrails precisously, and a pre-shearing divide cut the profile to length accuracily for next step - roll forming.

In order to undertake the large quantity, high speed and heavy-duty roll forming production. Brother Union Machinery engineers designed stiff and steady base, precise rolls made of qualified material, strong independent stands and shafts to assure the roll forming machine a long term service.

The finished guardrails are automatically stacking into certain number and the side motorized conveyors transfer the guardrail stacks to unloading station for forklift.

Brother Union Machinery, as a professional roll forming machine and coil processing equipment manufacturer, we have been providing highway guardrail beans, post production solutions, automatic produciton line, semi-automatic line, cost-conomically line.  

Customized roll forming machines and related equipment are available.  Just write us an email to us, we will send the proper proposal according to your requirements.

General Description of Highway Guard Rails

A highway guardrail or a traffic crash barrier is an important part of the highway safety system.  The main purpose of a guardrail is to lead a safe road for traffic participates.  Guardrails can make roads safer and lessen the severity of crashes.

Components of a standard guide rail: beam, post, and spacer. 

The horizontal beam of a guardrail is to redirect the vehicle back onto the roadway. and the spacer connects the beam and post, it also has a function of absorbing the collision impact.

Normally, the beams are made by roll forming, and some post are roll formed. 

As a professional roll forming machine manufacturer, Brother Union Machinery has been providing roll forming solutions for the highway guardrails production. 

We have produced roll forming machines for W-beam Guardrail, Thrie beam Guardrail, Sigma Post, C Post.
