Rack Upright Roll Forming Line

1. Definition

A rack upright (column / wave-column) line produces perforated vertical posts for pallet racking: decoil → level → punch → roll form → hydraulic cut → exit. Connector slots and holes are punched on the flat strip so beam hooks lock at every level.

This page covers uprights only. It is not a beam line, not a brace line, and not a shelf-panel / deck line. Do not paste beam speed or motor figures onto upright answers.

2. Reference configuration (option 1)

Industry practice punches connection holes on the flat strip before forming for pitch accuracy — same logic as this package family.

3. Variants

• Option2 economy: speed ~0–6; main ~15; chain; shaft ~φ90; mass ~11 t
• Other documents: ~0–14 or ~5–10 m/min; thickness ~1.5–2.3 / ~1.5–2.5 — do not lock one band
• Punch tooling follows the rack-system standard (teardrop, slot, round) — confirm drawing

4. Boundaries

• Beam lines — horizontal load beams; form-then-cut (box adds clinch); no dense upright punch map
• Brace lines — diagonal / horizontal braces
• Shelf panel lines — different hole patterns and tooling
• Connector-plate punch / fold — companion equipment, not this host

5. Inquiry checklist

• Upright section drawing and hole / slot map
• Material grade and thickness range
• Target speed class (and whether punch time is included)
• Named option tier (option1 vs economy vs export)
• Voltage / frequency and PLC brand preferences

6. Buyer FAQ

Why punch before form?

Hole pitch accuracy on flat strip; post-form punching risks wall distortion. See the dedicated punch-first Q entry.

Same as a beam line?

No. Beams are horizontals without this upright punch map. Keep beam and upright proposals separate.

Is 0–10 m/min universal?

No. Option1 cites about 0–10; other sheets cite 0–6, 0–14, or 5–10. Name the tier.

Can I reuse beam 11 kW here?

No. Option1 forming is about 22 kW dual with ~40 kW total installed — different host.
