1. Definition
A handrail second shaping roll former takes finished round tube and cold-forms it into a stair / balcony handrail cross-section (mushroom, slotted, or other drawing-driven shapes).
Industry “second roll forming” pages describe the same path: round pipe in, progressive dies, straighten/size, profiled handrail out — not a flat-coil W-beam guardrail mill and not a fence picket line.
2. Process outline
- Round tube load (matching OD)
- Multi-pass second shaping (~9 forming stands)
- Leveling / sizing (~3 stands)
- Exit
Upstream tube making (ERW) and downstream sawing / bending stay outside this single-machine scope unless the contract adds them.
3. Technical parameters
| Item | Reference |
|---|---|
| Input tube OD | ~48 mm and ~59 mm (procure matching round tube) |
| Wall thickness | ~1.5–2.0 mm; support ≤~2 mm |
| Speed | ~10 m/min |
| Stands | ~9 forming + ~3 leveling / sizing |
| Main / reducer | ~7.5 kW; 350 heavy-duty reducer |
| Shaft / rollers / bearings | Shaft ~φ60 (from φ70 bar), 40Cr QT; rollers GCr15 HT; bearings 6313 |
| Outline | ~3000 × 1350 × 1000 mm |
Market second-shapers may quote other ODs (e.g. 1.5-inch class) or ≤3.5 mm iron tube — keep those as context; lock OD and thickness on the proposal.
4. Input tube notes
This host does not start from flat coil. Buy or make round tube at the listed ODs first. Wall thickness must stay inside the supported band (~1.5–2.0 mm; ≤~2 mm) or confirm a special design.
5. Related machines
- Highway W-beam / thrie-beam guardrail — coil-fed roadside panels
- Fence picket / pale lines — fence family, not stair handrail
- ERW tube mills — upstream round-tube making
6. Applications
- Stair and landing handrail profiles from round tube
- Decorative / grip handrail sections matching the roller drawing
7. Inquiry checklist
- Finished handrail section drawing
- Input tube OD (48 / 59 or other) and wall thickness
- Material (CS / SS) and surface finish needs
- Whether sawing / bending auxiliaries are required
- Confirm not highway guardrail or fence picket RFQ
8. Buyer FAQ
Is this a highway guardrail line?
No. Highway W-beam / thrie-beam belongs to the guardrail pack — different tooling and process.
Do I feed coil or tube?
Feed round tube at the listed ODs. Coil-to-tube ERW is a different upstream machine.
Punching included?
The reference package is forming + sizing only — do not invent punch specs.
Can I run other ODs?
Market pages show other diameters. Lock any OD outside ~48 / ~59 mm on a named proposal with matching tooling.
Final ratings follow the named proposal. Price and lead time are out of scope.
