The Thrie Beam Steel Guardrail Making Machine is specially designed for manufacturing highway crash barriers used in modern road safety systems. These steel guardrails are widely installed on highways, bridges, slopes, and sharp curves to prevent vehicles from leaving the roadway.
ZTRFM FORMING manufactures advanced highway guardrail roll forming machines capable of producing both two-wave (W beam) and three-wave (Thrie beam) guardrails. Through a fully automated process, the machine converts steel coils into precise guardrail profiles with excellent strength, durability, and dimensional accuracy.
Moreover, one production line can manufacture multiple guardrail specifications. Therefore, manufacturers can improve production flexibility while reducing equipment investment.
Application of Highway Guardrails
Highway guardrails serve as an essential safety barrier in modern transportation systems. They are commonly installed along highways, road edges, bridges, and steep slopes.
When accidents occur, guardrails absorb the collision energy and redirect the vehicle back to the roadway. As a result, they significantly reduce vehicle damage and improve passenger safety.
Among different guardrail types, W beam guardrails and thrie beam guardrails are the most widely used because of their structural strength and cost efficiency.
Highway Guardrail Roll Forming Machine
ZTRFM FORMING provides a fully automatic guardrail roll-forming production line that integrates several production stages into a single system.
First, the steel coil is loaded by the hydraulic decoiler. Next, the leveling system straightens the material to ensure forming accuracy. After that, the hydraulic punching machine creates the installation holes required for guardrail assembly.
Then, the roll forming section gradually shapes the steel strip into the guardrail profile. Finally, the servo tracking cutting system cuts the guardrail to precise lengths.
Therefore, the entire process achieves high efficiency, high stability, and consistent product quality.

In highway construction projects, guardrails sometimes need to follow road curves or intersections. For this reason, ZTRFM FORMING also provides a guardrail bending machine.
This compact equipment allows operators to bend guardrails to different angles without damaging the steel structure. In addition, the machine can bend continuously while maintaining a smooth and accurate profile.
As a result, contractors can easily adapt guardrails to complex road layouts.
For customers who want to establish a full guardrail manufacturing factory, ZTRFM FORMING recommends the following three production lines:
- 2 Wave / 3 Wave Guardrail Roll Forming Machine
- Guardrail Bending Machine
- C Post Beam Roll Forming Machine
The C-post beam is used to install the guardrail system along the highway. These posts are typically galvanized to prevent corrosion and ensure long service life.
By combining these machines, manufacturers can build a complete guardrail production system for highway safety projects.

FAQ – Highway Guardrail Roll Forming Machine
What material is used for highway guardrails?
Highway guardrails are usually made from galvanized steel or carbon steel coils with thickness between 2 mm and 5 mm.
Can one machine produce both 2-wave and 3-wave guardrails?
Yes. ZTRFM FORMING guardrail machines can produce both W beam and thrie beam guardrails on the same production line.
What is the production speed of the guardrail machine?
The standard production speed is 8–12 meters per minute, depending on material thickness and punching requirements.
Is the machine fully automatic?
Yes. The machine integrates decoiling, leveling, punching, roll forming, and servo cutting into a fully automatic production process.
