W-beam/guardrail roll forming machine

W-beam also called two wave guardrails, which is used for high way for protection. The highway guard rail is the main form of the semi steel bar, and it is a continuous structure with corrugated steel fence board and supported by the main column. Vehicle of the collision, due to the corrugated steel guardrail plate has good crashworthiness and energy absorption effect, which is not easy be crashed and the vehicle and a driver by personnel have very good protection effect.

Based on the highway W-beam needs, the guardrail roll forming machine was developed. By the machine, we can make the guardrail in batch fully automatically. Here is one drawing profile of W-beam for your reference:
