1. Definition
A 41-series strut channel roll forming line produces PV mounting / support strut channels such as 41×21, 41×41, 41×62, and 41×83 on one host by spacer or roll changes. Typical flow: decoil → level → (servo) punch → form → cut → exit.
Not a triangular bracket (BRACKET) machine. Not the cassette quick-change host, not the Tianjin 20-stand tracking-shear package, and not the seismic package — those keep separate parameter tables.
2. Technical parameters (41-series host)
| Item | Reference |
|---|---|
| Profiles | Common four-on-one: 41×21 / 41×41 / 41×62 / 41×83 (Economic focus often 41×21 / 41×41) |
| Speed | Saudi Quotation band ~0–15 m/min; India ARS making ~25 m/min — list both, do not lock one |
| Main motor kW | Not unified across quotations — do not publish a single host kW here |
| Thickness | Quotation ~2.5 mm; making ~1.5–2.5 mm — do not lock a single public band |
| Material | GI or carbon steel; strength language ≤235 MPa class in source notes |
| Drive / change | Cast-stand gearbox; spacer / roll change (not cassette boxes on this page) |
| Punch timing | Online (pre-form) or post-form punch = configuration variants on this family |
| Line blocks | Decoiler, leveler, punch press/dies, forming host, hydraulic cut, exit table |
3. Sibling packages (do not merge params)
| Sibling | Keep separate |
|---|---|
| Cassette quick-change | ~0–15 m/min forming; host ~18.5 kW; hyd ~7.5 kW; ~22 stands/cassette + cog; ~125T punch |
| TJ20 (20-stand + tracking shear) | Punch/production ~0–20 m/min; host ~55 kW; tracking hyd ~5.5 kW |
| Seismic package | Multi-tier speed/power (e.g. ~10–15 / 8–18 / 8–25; ~25 kW or ~60 kW docs) — never as 41-only |
Never copy TJ20 55 kW, cassette 18.5/7.5, or seismic ~60 kW into the 41-series unique answer.
4. Applications
- PV mounting strut / C-channel support profiles
- Multi-section 41-family production with manual spacer or roll changeover
Market clues in source notes include Saudi quotation, India ARS, and Dubai video cases — clues only, not ratings.
5. Buyer FAQ
Is 25 m/min the only speed?
No. Keep the ~0–15 and ~25 m/min document tiers side by side.
Can I use TJ20 55 kW here?
No. Host power is not unified on this 41-series page.
Is online vs post-form punch a different machine line?
No — punch timing is a configuration variant on the same product family.
6. Verification notes
- Publish only numbers that appear on the named FAQ / parameter sheet for this leaf.
- When two source documents disagree, list both tiers with labels — do not average.
- Host ratings stay separate from auxiliaries (curving, stacking, offline presses) unless the FAQ bundles them.
- Directory identity is fixed; open fields stay blocked until a proposal confirms them.
Final ratings follow the named technical proposal. Price and lead time are out of scope.
