Guardrail Line Speed: Pure Forming vs With Punch and Shear

1. How to read speed

Listed speed depends on what the note includes. A pure forming figure is not the same as a production figure that already accounts for hydraulic punching and cut-to-length. Always ask: forming only, or punch + shear included?

2. Reference tiers

Market pages may advertise wider bands (e.g. 8–25 or 10–20 m/min) — industry context only; commercial answers stay on the named scheme above.

3. Source conflicts

• Pack docs may also show bands such as about 8–20 m/min or about 8–12 m/min on alternate schemes
• Those alternate bands must not be merged into the dedicated gearbox 15/10 reference without labeling
• Drive/shear changes (chain, front shear) can invalidate a direct 15/10 comparison

4. What to ask on the RFQ

• Is the quoted speed forming-only or with punch + shear?
• Which host: dedicated W2, dedicated W3, or hoist-change dual?
• Which drive/shear package does the speed belong to?

5. Inquiry checklist

• Target beam length and hole pattern (affects punch/shear cycle)
• Named host and drive/shear package
• Two labeled figures if both forming-only and production speeds are discussed
• Do not compare dual 5–10 to dedicated 15 without cycle labels

6. Buyer FAQ

Can I compare hoist-change 5–10 to dedicated 15?

No — different host proposals and cycle definitions. Dual guidance already tends to include punch/shear; dedicated 15 is forming-only on the reference package.

Is 10 m/min “slower than advertised 15”?

Usually no contradiction — 15 is forming reference; 10 includes punch and shear on the same dedicated package.

Why do some brochures show 8–20 m/min?

Alternate scheme docs and market pages use wider bands. Keep them labeled; do not average into one invented public speed.

Does thickness change the published speed?

Heavier coil and harder grades load the cycle. Thickness bands conflict across sheets — lock both thickness and speed on the same proposal.
