Rack Beam Roll Forming Line

1. Definition

A rack beam line forms warehouse shelving load beams — open C-channel or closed box after clinching / seaming. Beams hook into upright slots as the horizontal members of a pallet-rack bay.

This page covers the beam family only. It is not an upright column line, not a brace / diagonal line, and not a shelf-panel or pallet-deck line.

2. Reference configuration (C-beam)

Typical open-C route: uncoil → guide → roll form → hydraulic cut → exit. Speeds and host power stay on this beam table — do not borrow upright punch or motor figures.

3. Box / clinch variant

Box beams add a clinching / seaming stage after forming C halves (or a self-locked single-strip box on some BOMs). Box documents may list C-section about 4–12 m/min with main ~15 / hyd ~5.5, and clinch about 4–8 m/min with another ~11 kW — segmented configuration, not a substitute for the C-beam 11/4 table.

Industry box-beam lines likewise form two C sections then seam. Market speeds (often 10–30 m/min class) stay as industry background — keep them off the commercial C-beam row unless the named proposal states them.

4. Boundaries

• Upright / column lines — punch-before-form vertical posts; separate process and power table
• Brace lines — diagonal / horizontal braces; different tooling
• Shelf panel / deck lines — panel punching and forming, not load beams
• Clinching stage — beam-line configuration / auxiliary, not a new encyclopedia product family

5. Inquiry checklist

• Open C vs closed box (and clinch method)
• Section drawing, thickness, and material grade
• Target speed class and cut-length range
• Whether end connectors / welding are in scope
• Voltage / frequency preferences

6. Buyer FAQ

Same machine as upright?

No. Uprights punch connector holes before forming on a separate line. Beam hosts form then cut; box adds clinch.

Is the clincher a new product line?

No. It is a configuration / auxiliary process on the beam family — keep clinch power on its own BOM line.

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

No. Keep C-form and clinch power separate. Do not silently sum them into the open-C 11/4/15 table.

Typical C-beam speed?

About 0–12 m/min on the recommended C-beam package. Box C-form and clinch segments may cite different bands — confirm the named proposal.
