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. 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.
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
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.

W-beam has a double-wave shape (used for standard highways).
Thrie-beam has a triple-wave shape (for higher impact resistance).
The machine can produce both in one machine.
Yes, the machine can be equipped with a punching unit to create pre-punched holes for easy installation.
Typically 2.0mm – 4.5mm, but heavy-duty versions can go up to 6mm.
Assuming 8-20 m/min, it can produce 500–1,500 tons/month (depending on shifts).
Yes, we offer on-site installation, testing, and operator training.
Yes, options like automatic coil loading, stacking systems, and robotic arms can be integrated for full automation.
