Highway Guardrail Roll Forming Machine
Guardrail or Guard rail, is a system to keep errant vehicles from straying into dangerous areas of highway. The thickness of the guardrail can be up to 4.5mm.
The Types of Guardrail
The most common type of Guardrail used now is W-Beam. also called two waves guardrail. And now Thrie-Beam guardrail is new one and which is a type of guardrail that is similar to two pieces of W-Beam Guardrail formed into one single section.
Two waves guardrail, W-beam guardrail is widely common used in the whole world.
Thrie-beam, also named three waves guardrail, which is for heavy requirement
The end of the guardrail usually formed as a wing type
Guardrail wing end is the ends of every group of guardrail system
The Layout of Highway Guardrail Roll Forming Machine is Uncoiling– Leveling– Punching– Cutting–Roll Forming– Auto Stacking

Entrance And Guide Roller: 45# steel, ￠65mm, HRC48-52° surfacechromed
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
Punch Hole device
The punches will be connected to a single hydraulic unit with tank, motor, pump, pressure control valves, pressure gauges, solenoid valves, hydraulic hoses, all designed to operate safely at the required operating pressure.
The punches and doilies will be CR-12, HRC 58-62 and chrome coating. Both punches and doilies should be easily replaceable without disassembling of the whole units.
The whole punching operation will be automated and controlled by a program installed in the PC which is located in the operator's console.
