2 waves 3 waves highway guardrail forming machine is a fully automated machine that processes coiled steel strips (usually made of Q235 or Q345 steel) into final guardrail through a series of continuous cold bending forming processes. The entire production line integrates multiple stages such as uncoiling, leveling, forming, length cutting, and punching.
