The high-speed guardrail plate forming machine is a specialized cold bending forming equipment for highway traffic safety facilities. It can continuously roll Q235/Q345 galvanized steel coils into two wave (W-shaped) and three wave guardrail plates, integrating the entire process of punching, forming, and cutting. The finished product has high strength and strong impact resistance, and is widely used in anti-collision protection projects for highways, national highways, bridges, and municipal roads.
