DUWELL guardrail roll forming machine can make the two wave (W beam) and three waves (thrie beam) rails in one machine. The line includes decoiler, leveler, servo feeder and pressing machine, roll forming, hydraulic cutting device, stacking system and controller. It is complete automatic production line. As one of the professional guardrail roll forming machine suppliers, we make the machine according to customer's required material thickness. If the customer just use the thickness below 2.5mm, we just use economic construction for the machine like chain transmission, with hydraulic punching device for holes.
If the customer use material thickness 3.0~5.0mm thickness, we will make heavy duty construction, with gear box transmission, 315ton pressure pressing machine for the holes.
This advanced configuration ensures that the DUWELL guardrail roll forming machine maintains stability, strength, and high-precision forming performance.
A highway guardrail roll forming machine is an advanced production line designed to manufacture W-beam, Thrie-beam, and other highway safety barriers from metal coils (galvanized steel, stainless steel, or aluminum). This machine ensures high precision, durability, and efficiency in producing guardrails. As a professional manufacturer, DUWELL provides a high-performance guardrail machine designed to meet modern highway protection standards. DUWELL is recognized not only for its engineering but also as one of the trusted highway guardrail roll forming machine manufacturers across global markets.
Uncoiler – Supports and feeds the metal coil into the machine.
Leveling Unit – Flattens the coil to prevent deformities.
Roll Forming Stations – Progressive shaping of the guardrail profile (W-beam, Thrie-beam, etc.).
Punching Unit (Optional) – Adds bolt holes for guardrail connections.
Hydraulic Cutting System – Cuts guardrails to exact lengths (6m, 12m, or custom).
PLC Control Panel – Ensures precision in length, punching, and speed.
Run-out Table – Supports and stacks finished guardrails.
