Highway Guardrail Roll Forming Machine

What’s guardrail?

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.
three waves guardrail
Thrie-beam, also named three waves guardrail, which is for heavy requirement

The end of the guardrail usually formed as a wing type
