Highway Guardrail Roll Forming Line
Overwiew of Guardrail Machine
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.

Roll Forming Mill
This roll former uses the independent Stands with gear box transmission. Reduction box drives the down shaft, the up and down shafts adopt synchromesh gear( for necessary roll station only)
Roller Material
Roller material adopts Cr12, after quenching treatment the hardness is HRC 58 – 62.
Marks on the side of rollers and surface of spacers, for easy maintainence.
Quick Installation
Aviation Plugs and Sockets for easy installtion, easy maintainence of the roll forming line. Save the buyer's time and start the machine to produce in shortest time.
Highway Guardrail Profiles
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.
W-beam Guard RailBrother Union Machinery has manufactured roll forming machines to produce w-beam guardrails. For large quantity standard guard rail beams production, Compared to a press brake, a roll forming line by Brother Union Machinery is a better choice. |
Thrie-beam Guard RailA thrie-beam steel guardrail is just like a double W-Beam Guardrail formed in one single profile, it is more fit to heavier vehicles in highway traffic. Brother Union Machiney has plent experience in the 3-wave road barrier roll forming solutions. |
Sigma Post for Guardril BeamBrother Union Machiney can produce roll formers for Sigma Post in highway guardrail system. Nomally the material of te post is carbon steel with surface galvanized. We can also design custom fence post roll forming machine to produce according to customer's requirements. |
C Post for Guardril BeamBrother Union Machiney can produce roll formers for C Post in a highway guardrail system. Nomally the material of the posts is carbon steel with surface galvanized.. |
U Post for Guardril BeamBrother Union Machiney can produce roll formers for U Post in a crash barrier system. Nomally the material of the posts is carbon steel with surface galvanized.. |
We are always here to serve guardrail manufacturers, our engineers and technicians are experienced in custom roll forming solutions.
