We had experience of Russian type Guardrail, there are four lines totally:① two wave guardrail roll forming machine, ② U post roll forming machine,③ connection punching line and ④end wind punching line.
This U Roll Forming Machine can be designed for thickness 4-5mm, it is widely used as post of guardrail. We use forged iron stands(see picture) and gearbox driving to make sure this machine can longly work in a stable situation.
