Highway W-Beam Guardrail Roll Forming Machine 15m/min PLC ZTRFM highway guardrail roll forming machine

Overview

W-beam guardrail cross-section drawing with installation reference and full roll forming line

The ZTRFM High-Accuracy Highway Guardrail Roll Forming Machine produces W-beam (two-wave and three-wave) highway guardrail sections from hot-dip galvanized steel coil at 15 m/min. Steel coil is fed through a straightening unit, shaped progressively through multiple Cr12 roller stations mounted on an independent gantry-style archway frame, punched by a hydraulic punching unit and cut to length by a flying shear. The line runs at up to 15 m/min and processes material thicknesses of 2.5–4.0 mm with a maximum working width of 800 mm.

The machine is painted blue throughout and driven by two 22 kW motors. Control is by a Siemens or Delta imported-brand PLC. The line is used by highway construction contractors, road infrastructure product manufacturers and guardrail suppliers worldwide. Applicable profiles: 2-wave (W-beam) and 3-wave guardrail to international road standards.

• 2-wave and 3-wave W-beam highway guardrail profiles
• Forming speed 15 m/min; material thickness 2.5–4.0 mm; max. working width 800 mm
• Drive: 2 × 22 kW; PLC Siemens / Delta imported brand
• Cr12 rollers; 40Cr shafts; Cr12Mov cutting blade; SKD11 punching dies
• Independent gantry-style archway main frame
• CE / BV / STV / ISO certified; lifetime technical support

Key Features

• 2-wave and 3-wave profiles on the same line. The roller toolset is configured for both standard 2-wave (W-beam) and 3-wave guardrail sections, covering the most widely specified highway safety barrier profiles.
• Independent gantry-style archway frame. The main frame uses an independent-type gantry-style archway structure, providing high rigidity and precise shaft alignment across the full material width under heavy-gauge forming forces.
• Premium roller and tooling materials. Forming rollers are Cr12 material; shafts are 40Cr alloy steel; the cutting blade is Cr12Mov; punching dies are SKD11 — selected for hardness and wear resistance when processing 2.5–4.0 mm galvanized steel.
• Hydraulic punching unit. An integrated four-column hydraulic press punches the oval fixing holes in-line to the standard guardrail hole pattern, eliminating secondary operations.
• Dual 22 kW drive. Two 22 kW motors provide the torque required for continuous forming of heavy-gauge material at 15 m/min.
• PLC Siemens / Delta control. Imported-brand PLC manages forming speed, punching cycle and cut length; parameters are set once per profile and stored for repeat production runs.
• CE / BV / STV / ISO certified; lifetime technical support. The machine ships with CE, BV, STV and ISO certification documentation plus machinery test report and video inspection. Lifetime technical support is provided.

Technical Specifications

Machine Structure

The forming line runs left-to-right on a long blue-painted gantry-style frame. Steel coil enters through a straightening and feeding unit; the strip passes through a row of Cr12 roller stations that progressively form the W-beam wave profile. Partway along the line, a four-column hydraulic press punches the guardrail fixing holes in-line. Toward the exit, a hydraulic flying shear cuts each section to the programmed length and deposits it on the run-out conveyor.

Profile & Applications

W-beam guardrail sections produced on this line are used as vehicle restraint systems on highways, expressways, mountain roads, bridge edges and urban arterials. The 2-wave profile is the international standard highway barrier section (310 mm total width, 85 mm wave height per the cross-section drawing); the 3-wave variant provides higher containment performance for heavy-vehicle routes. Finished sections are hot-dip galvanized and punched with oval fixing holes for post connection.

FAQ

What profiles can the machine produce?

2-wave (W-beam) and 3-wave highway guardrail sections; profile dimensions are customizable per local road standard or drawing.

What steel thickness does it process?

2.5 mm to 4.0 mm; maximum working width 800 mm.

Are the fixing holes punched in-line?

Yes. An integrated hydraulic punching unit punches the oval fixing holes to the standard guardrail hole pattern in-line with the forming process, eliminating secondary operations.

Can the voltage be changed?

Yes. The standard voltage is 220 V and can be customized at order confirmation.

What is the delivery lead time?

50 days for one set; 70 days for two sets.

What after-sales support is provided?

Lifetime technical support; machinery test report and video outgoing-inspection provided with the shipment. CE, BV, STV and ISO certifications included.
