Highway Guardrail

Highway guardrails produced by our highway guardrail roll forming machine  are the main form of semi-rigid guardrails. They are a continuous structure consisting of corrugated steel guardrail panels joined together and supported by main posts.  They absorb energy during vehicle collisions, making them resistant to damage while also providing excellent protection for vehicles and their occupants.

Highway Guardrail Roll Forming Machine

A Highway Guardrail Roll Forming Machine is a specialized, high-precision industrial system designed for the continuous, automated production of metal guardrail panels (also known as safety barriers or crash barriers) used on roads, highways, and bridges.

This machine utilizes a roll forming process, where a pre-painted or galvanized steel coil is progressively shaped through a series of precisely engineered roller dies. Each set of rollers incrementally bends the flat metal strip until it achieves the final, complex cross-sectional profile—typically a deep, multi-curve design like the three-beam or W-beam—without altering the material's thickness.

Key Features and Advantages:

High Efficiency & Automation: Enables uninterrupted, high-speed production, significantly increasing output compared to manual or stamping methods.

Consistent Quality: Produces guardrails with uniform dimensions, precise geometry, and excellent surface integrity along the entire length, which is critical for safety performance.

Material Efficiency: Minimizes waste by using coiled steel and employing a continuous forming process.

Flexibility: Modern machines are often modular, allowing for quick changes in roller dies to produce different guardrail profiles (e.g., different heights, wave patterns) to meet various national standards (AASHTO in the US, EN in Europe, etc.).

Integrated Operations: A complete production line typically includes auxiliary stations such as:

Decoiler: Holds and feeds the heavy steel coil.

Guide & Straightening Unit: Ensures flat entry of material.

Pre-punching/Hole-piercing System: Punches mounting holes at precise intervals before the forming stage.

Cut-off System: Accurately cuts the formed guardrail to the required length (flying cut-off for continuous operation).

Run-out Table & Stacker: Handles and collects the finished products.
