High speed Guard Railway Crash barrier roll forming machine can make W beam guardrail, flex-beam guardrail, three wave guardrail and Box Beam Guardrail, also can be designed as two waves or three waves profiles in one machine, you just need to add some forming stations at the end of the machine according to our drawing. The guardrail’s thickness is usually 2.0mm-4mm, steel material is Q235.

2. Leveling
Main features of the machine:
The leveling roller’s mechanical property such as rigidity and roughness concentration of the surface are rising very much after hardening and tempering. It includes pinch roll and leveling roll. The pinch roll can adjust along. The leveling roll uses the whole structure. There are two adjusting point at the front and the end. It can form a certain banked angle to improve the leveling quality. The feeding port of the leveling machine has a pair of guide plain-barrelled roll and two pairs of guide vertical roll. The guide vertical roll can moves centered or moves at the same time. It is adjusted by hand wheel, so it is convenient to centered.
