Guardrail and Fence Roll Forming Solution
Highway W-beam guardrail line with 2-wave / 3-wave swap modules. Example: 3.0 mm strip, 15 or 20 passes, 10 t decoiler, 380 V / 50 Hz. Posts and mesh fence are separate hosts.
Who it's for
Highway and fence plants that roll W-beam rails from heavy strip and need a clear host before mixing posts, mesh fence or light ornamental railing.
Pre-punch
Pre-punch
three hydraulic stations before form.
Posts and mesh
Posts and mesh
different hosts, quoted separately.
How to choose a line
- 2-wave and / or 3-wave highway W-beam rail -> W-beam guardrail line with swap modules (Example specification on this page)
- Guardrail posts -> Post line (Quoted separately from the rail mill)
- Mesh / panel fence -> Mesh fence package (Ask separately)
- Light ornamental railing -> A different fence family (Not this 3.0 mm highway example)
Example specification
One delivered example. Final numbers follow your quotation.

What to send for a quote
- Year-one mix: 2-wave rail vs 3-wave rail vs posts vs mesh fence
- Section drawings and hole map (head / tail / mid)
- Steel grade and thickness (example 3.0 mm)
- Whether 2-wave and 3-wave share one mill with swap modules
- Site voltage / frequency / phase (example line 380 V / 50 Hz)
- Whether a 10 t car decoiler and lift stacker are required
- HMI languages (example line ZH / EN)
Check before you quote
Highway rail vs light fence
Highway rail vs light fence
This example is 3.0 mm highway W-beam, a different host from light ornamental railing.
Rails and posts
Rails and posts
W-beam rail and post lines are different hosts.
2-wave vs 3-wave
2-wave vs 3-wave
Pass count follows the module (15 vs 20 on this example). Confirm which waves you will run.
FAQ
Can one mill make 2-wave and 3-wave rails?
This example is built as a swap-module mill: 15 passes for 2-wave, 20 passes for 3-wave. Confirm both modules on the quotation.
Where do 3.0 mm and 10 t come from?
From the technical proposal that matches that W-beam line. Posts and mesh fence use their own files.
Is this the same as a cable-tray or rack line?
Highway W-beam is a different product family from cable tray or storage rack.
How are price and lead time quoted?
