Freeway Barrier Profile Roll Forming Machine Cold Bending Use Multi-rollers Stations by Huge Power 45 Kw Motor
The expressway fence is the main form of a semi-steel fence, which is a continuous structure that is stitched with a corrugated steel guardrail and supported by the main pillar.
When the vehicle collides with it, it is not easy to be crashed because of the good impact resistance and energy absorption of the corrugated steel guardrail, and it can also protect the vehicle and the crew.
According to the differences of the corrugations and punched holes, the guardrail roll forming machine are designed with two working methods as demonstrated below.
1. The first one is making the guardrail by punching first and then forming the shape. This is adopted by most of manufacturers.
2. Our machine, unlike common products on the market, forms the shape first and then punches holes. This method ensures the high precision of punching positions, thus satisfying even the most captious customer. Meanwhile, the inclined punching system also contributes to the high punching precision, and this facilitates the connection of guardrails.
Aside from the above, this guardrail roll forming machine is able to manufacture double-wave and triple-wave guardrails, and pressing dies can be applied to produce C&U posts. In addition, our machine could be designed to work with hydraulic decoiler and stacker upon customer's request.
