Main T vs Cross T: Separate Machines, Same Product Family

1. Short answer
Main Tee and Cross Tee usually ship as separate machines or a matched set, but they belong to the same ceiling T-grid family. Punch maps, lengths, and connectors differ — do not assume one mill casually makes both, and do not merge their speed / power sheets into one “standard T” table.
2. Why separate mills
- Main T — primary load-bearing runners (industry examples often ~3600 mm class)
- Cross T — interlocking modules (often ~600 / 1200 mm) with different end punches
- Wall angle — third machine in a full commercial kit; not T-mill ratings
Public full-set lines list Main T + Cross T + Wall Angle as three cooperating machines. Semi-automatic vs full-automatic is a configuration tier, not a reason to merge Main and Cross parameters.
3. Parameter reading
| Item | Main T reference examples | Cross T / paired notes |
|---|---|---|
| Role | Primary carrying T bar | Secondary cross tee |
| Section example | 24×38 mm at about 0.3 mm on one quote | 24×28 mm cross profile on a paired quote |
| Stations / shaft (family) | About 16 stands; shaft about φ40 mm class | Confirm per mill — do not copy Main blindly |
| Process sketch | Uncoil → level → form → punch → cut → exit | Same family idea; end punch and length logic differ |
4. Speed tiers
| Documented tier | Speed context | Power context |
|---|---|---|
| Full-automatic Main T reference | About 0–30 m/min (other notes ~16 m/min) | Main ~4 kW; hydraulic ~7.5 kW |
| 24–38 Main T reference | About 10–20 m/min (tracking punch/cut up to ~20) | Main ~5.5 kW; hydraulic ~5.5 kW |
Self-check: Compare Main vs Cross only on the same proposal tier — do not mix 0–30 with 10–20 as one “standard T speed,” and do not invent a single Cross-only public speed from Main text alone.
5. Wall angle note
If a set quotation also lists wall angle / perimeter angle, treat it as edge / accessory equipment. Do not merge its parameters into the Main T machine’s only public rating.
6. Boundaries
- Partition C / U stud-track lines are a different family
- Angle bead / net wall angle is not ceiling T
- Do not create a fake “one mill for Main + Cross” claim unless the proposal writes a dual-purpose design
7. Inquiry checklist
- Main T and Cross T drawings (section + connector / end punch)
- Whether wall angle is in the same package
- Semi-auto vs full-auto tracking punch/cut
- Which speed / power tier the quote uses (0–30 class vs 10–20 class)
- Material thickness and finish
8. Buyer FAQ
Can Cross T dies drop into a Main T mill?
Not as a casual swap. Ask for a dual-purpose written design if offered.
Are Main T and Cross T the same product family?
Yes — same ceiling T-grid family — but usually separate machines or a matched set with separate ratings.
Which speed should I put on the inquiry?
Name the proposal tier. Do not average 0–30 m/min with 10–20 m/min into one number.
Does a full kit include wall angle?
Often yes as a third machine. Keep its ratings off the Main T sheet.
Final ratings follow each named Main/Cross proposal. Price and lead time are out of scope.
