Typical Rack Beam Line Process Flow (C-Beam and Box Beam)

1. Process purpose

Produce horizontal load beams that hook into upright slots — either open C-beams or closed box beams with clinched / seamed seams. This flow page stays on the beam family. Upright punch-before-form sequences belong on the upright process page.

2. Open C-beam route

1. Decoil
2. Guide / feed (leveling when specified)
3. Roll form the C-section
4. Hydraulic cut-to-length
5. Exit / collect

This is the base host path for open C-beams. Speeds and host power stay on the beam equipment page — not re-invented here as a second “truth.”

3. Box / clinch route

Industry practice forms two C-channels, then nests and locks them on a seaming / clinching machine into a closed box beam. Optional end-connector welding and stacking sit downstream of seaming.

1. Produce C-channels on the roll former (as above)
2. Transfer / overturn and nest two channels
3. Seam / clinch (box connection machine)
4. Optional welding of end clips → exit

Some lines form a self-locked box from one strip; that is a different BOM — confirm on the named proposal.

4. Speed and power notes

5. Quality checkpoints

• Section height / width vs drawing after forming
• Cut-length tolerance before clinch transfer
• Seam lock integrity and diagonal control on box beams
• Do not mix upright punch cadence into beam speed quotes

6. Buyer FAQ

Is the clincher a new LINE?

No — it is a configuration / auxiliary process on the beam family, not a separate encyclopedia line ID.

Can I quote one power number for “box beam”?

No. Keep C-form and clinch power on separate lines of the BOM.

Does this flow include upright punching?

No. Upright columns punch before forming on their own line. This page is beam-only.

Where do end connectors fit?

Usually after seaming / cut-off as optional welding or clipping — confirm whether they are in the beam proposal scope.
