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 industrial production line used to manufacture W-beam, Thrie-beam, and other highway safety barriers from steel coils, such as galvanized steel, stainless steel, or aluminum. Our guardrail roll forming machine integrates uncoiling, leveling, punching, roll forming, and cutting into one continuous process, ensuring high efficiency and consistent guardrail geometry.
As one of the professional highway guardrail roll forming machine manufacturers, DUWELL supplies high-performance equipment that complies with international highway safety standards and is widely used in infrastructure and transportation projects worldwide. Our guardrail roll forming machines are manufactured in our own guardrail roll forming machine factory, ensuring full control over design, machining, assembly, and quality inspection.
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.
