Highway Guardrail Machine

The highway guardrail machine is a specialized roll forming system designed for manufacturing high-speed crash barriers used on highways. These guardrails enhance road safety by preventing vehicles from veering off the road and reducing the severity of accidents. Our roll forming equipment is engineered to produce W-beam and three-wave guardrails with precision, ensuring compliance with international highway safety standards.

Production Process

The automated production line follows a streamlined process to maximize efficiency and ensure high-quality output:
Automatic decoiling → Leveling & feeding → Servo feeding → Hydraulic punching & cutting → Fast feeding → Roll forming → Automatic stacking
