Customized Roll Forming Machine
Truck Beam Roll Forming Machine
A truck beam line built from the beam drawing: decoiler, feeding device, hydraulic punching, main forming, cutting and control cabinet. The section is a structural beam, so station count, shaft size and motor rating are calculated from the section modulus rather than copied from a catalogue.
- Sheet thickness 3.0–5.0 mm
- Forming stations per section
- Forming speed 6–12 m/min
- Main motor 45–75 kW
Applications & material
What this machine is built to produce
The same frame serves different buyers depending on the profile and the material grade. Start from the application closest to your project, then check the section sizes below.
Where it is used
- Truck chassis beams and car beam sections for commercial vehicle builders.
- Trailer and body builders who need a beam section that is not rolled locally.
- Plants replacing an imported beam line and needing tooling made to the same drawing.
Suitable material
- High-strength low-alloy steel (Q345 / S355)
- 3.0–5.0 mm
- Mild steel (Q235)
- 3.0–5.0 mm
- Hot-rolled pickled coil
- 3.0–5.0 mm
- Weathering steel (Corten)
- 3.0–5.0 mm
Target profiles
- Truck beam, hat or C section
- Beam with a variable web depth (tapered)
- Beam with flange and web holes punched in line
- Section per your beam drawing

Technical data
Truck Beam Roll Forming Machine specifications
Values below are for the standard build of this model. Thickness range, station count and motor rating are re-calculated when the profile or the steel grade changes.
Send your profile drawing| Parameter | Value |
|---|---|
| Sheet thickness | 3.0–5.0 mm (per drawing) |
| Forming stations | per section, typically 16–24 |
| Forming speed | 6–12 m/min |
| Shaft diameter | φ120–160 mm |
| Main motor | 45–75 kW |
| Punching | Hydraulic punch, web and flange |
| Cutting | Hydraulic post-cut, section-shaped die |
| Control | PLC + touch screen |
Heavy-gauge beams are quoted per drawing: station count, shaft diameter and motor rating are calculated from the section and the grade, so the table above is a range, not a fixed specification.
Working process
From coil to finished profile
The sequence below is the standard layout for this model. Stations are added or removed when the section needs more forming passes.
- 01 Decoiling Heavy decoiler sized to the coil weight — 5 mm coil is not light.
- 02 Feeding Powered feeding device with a straightener.
- 03 Hydraulic punching Web and flange holes punched before forming.
- 04 Main roll forming Heavy forming stands with large shafts and gearbox transmission.
- 05 Hydraulic cutting Post-cut with a beam-shaped die.
- 06 Run-out table Heavy roller table for long, heavy beams.
Main components
- Heavy decoiler Sized to coil weight and ID, with a coil car.
- Feeding and straightening device Powered feed with a straightener for thick coil.
- Hydraulic punch Web and flange punching ahead of forming.
- Main forming machine Heavy stands, φ120–160 mm shafts, gearbox driven.
- Hydraulic cutting device Post-cut, die shaped to the beam.
- PLC control cabinet Length, hole pattern and batch settings.
- Run-out table Heavy-duty roller table.
Optional configuration
Samples & running line
Profiles from this machine, and the line in motion
Every line is sampled before shipment. Photos below are from the build of this model; the video shows the line running on production material.
First-off samples are measured for web depth, flange width, hole positions and straightness over 3 m, and the report is issued with the machine.
Video on request
Ask for the latest running video
We record a fresh clip of this model before shipment. Ask for it and we will send the current video, plus a live call from the factory floor if you want to see the line under power.
Profile range
- Truck beam, hat or C section
- Beam with a variable web depth (tapered)
- Beam with flange and web holes punched in line
- Section per your beam drawing
Engineering & service
Custom build, installation and after-sales
A roll forming line is only finished when it runs on your material at your output. These three parts of the scope are quoted together with the machine.
Custom engineering
Truck beams are safety-critical: the section modulus, the hole positions and the fatigue detail come from the vehicle designer. We build to the drawing and issue a first-off inspection report with the measured section, so your engineering team signs off before shipment.
- Tooling cut to your drawing or sample
- Electrics to your plant voltage and frequency
- Layout and foundation drawing before shipment
Installation & training
An engineer supervises installation and trains your operators on the actual line — not on a generic manual. Training covers coil loading, size change, tooling change and daily maintenance.
- On-site commissioning and first production run
- Operator training on your material
- Remote video support if travel is not practical
After-sales support
A 12-month warranty on the mechanical parts, with a 24-hour response on technical enquiries. Wearing parts — rollers, punch dies, hydraulic seals — are kept in stock for fast dispatch.
- 12-month mechanical warranty
- Spare rollers and dies from stock
- 24-hour response on remote support
What we need from you
Four inputs that decide 80% of the design
- 01 Profile drawing with dimensions and tolerances
- 02 Material type, thickness range and steel grade
- 03 Target output per shift or per day
- 04 Plant voltage, frequency and available floor length

FAQ
Questions buyers ask about this machine
Answers come from real quotation discussions on this model. If your question is not here, ask it in the form below and an engineer will answer it directly.
Can you make tooling to an existing beam drawing?
Yes. Send the drawing with tolerances and the material grade. We confirm the roll design against the section modulus and quote the tooling separately if you already have a frame.
Why is the line speed lower than a panel line?
Thick high-strength steel needs more forming stations and more power, and the cut-off is heavier. Running a 5 mm beam at panel speed would distort the section and shorten tooling life.
Is the beam tapered or constant depth?
Both are possible. A tapered beam needs a variable-depth tooling arrangement and a different control strategy; tell us at enquiry stage because it changes the frame design.
What is the delivery time?
70–100 days after drawing approval, because the heavy rolls and the cut die are machined to order.
