Highway guardrail machine

Highway guardrail roller forming machine is used for mass production of online punching guardrail, guardrail is the most commonly used steel structure in highway construction. According to different standards, there are two different models of guardrail: two-wave guardrail and three-wave guardrail.

What is highway guardrail?

A highway guardrail is a system that prevents out-of-control vehicles from straying into dangerous areas of a highway. The thickness of the guardrail can reach 4.5mm.

Type of guardrail:

The most common type of guardrail in use today is the W-beam. Also known as two wave guardrail. Now the three-beam guardrail is a new type of guardrail, which is similar to two W-beam guardrail forming a separate section.

Double wave guardrail and W beam guardrail are widely used in the world.

Three beams, also known as three wave guardrail, are used for heavy duty requirements: the end of the guardrail usually forms an airfoil, and the wing end of the guardrail is the end of each set of guardrail systems.

Working flow of guardrail machine

Unwinding → feed leveling → hydraulic punching (optional) → roll forming → hydraulic length cutting→output table
