1. Definition
A seismic / PV strut channel line roll-forms U41-family support channels used in seismic bracing and PV strut applications. Evidence is strut / U41 channel — not a triangular BRACKET connector machine.
Punch may be online before forming with tracking saw, or offline after forming on a dual-press layout, depending on the named package.
Keep 41-series, cassette, and TJ20 parameter tables on their own pages.
2. Technical parameters (multi-tier — do not lock one)
| Item | Document tiers (list, do not average) |
|---|---|
| Speed | Strut doc ~10–15 m/min; package-1 ~8–18; package-2 ~8–25 → blocked single speed |
| Main motor | Strut doc ~25 kW (~26 stands); package-1/2 ~60 kW (~22 passes) → blocked single host kW |
| Stands | ~22–26 (document dependent) |
| Profiles | Strut doc: 41×21 / 41 / 52 / 62; packages: U41×41–82 family (52/62/72/82 etc.) |
| Thickness | Strut doc ~2.5 mm; packages ~2–3 mm — do not lock one band |
| Material | Often Q195/Q235 galvanized coil |
| Punch | Online + tracking cut, or offline dual punch; Strut doc punch ~80T language |
| Drive / PLC | Gearbox; PLC brand per contract (Xinje cited on one package) |
3. Sibling packages (do not merge params)
| Sibling | Do not import as seismic-only |
|---|---|
| 41-series | ~0–15 vs ~25 m/min; host kW not unified |
| Cassette | ~18.5 / 7.5 kW; ~0–15 m/min |
| TJ20 | ~55 kW host; ~0–20 m/min |
| Shelving upright video | SKIP — not this strut family |
4. Applications
- Seismic bracing strut channels and PV strut of the same U41 family
- Plants choosing online vs offline punch layout per package drawing
Shandong site media are case clues only. Skip any shelving-upright footage mixed into the same folder.
5. Buyer FAQ
Is seismic strut the same as triangular BRACKET?
No. This page is strut / U41 channel evidence.
Which speed should I publish?
List the document tiers (~10–15 / ~8–18 / ~8–25) or wait for the named proposal — do not invent one unique number.
Is 60 kW always correct?
No. Another strut document cites about 25 kW with a different stand count — keep sources labeled.
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.
