Product Description
SF-20 Commercial Grade Galvanized Chain Link Posts & Framework — Heavier Wall for Added Strength
- Heavier commercial wall — A step up from .065" residential tubing for increased rigidity and durability.
- Hot-dip galvanized — Zinc coating helps protect against rust and outdoor wear in demanding environments.
- Swedged top-rail option — Tapered ends let one rail fit into the next for continuous runs (no sleeve needed).
- Built for tougher jobs — Great for taller fences, windier sites, or where privacy slats/accessories add load.
- Standard-fit hardware — Compatible with common chain link fabric and fittings for straightforward installs.
SF-20 is commercial-grade framework for projects that need more strength than .065" residential tubing. Use it for line and terminal posts, top/brace rails, and welded gate frames on high-traffic or wind-exposed sites. For a complete kit, pair your framework with compatible chain link fabric and galvanized rail sleeves (if you’re not using swedged top rail).
Typical Sizing & Use
- Top/brace rail: commonly 1-3/8" or 1-5/8" OD on commercial runs.
- Line posts: often 1-7/8" (2" nominal) or 2-3/8" (2-1/2" nominal) actual OD.
- Terminal posts (corners/ends/gates): frequently 2-7/8" (3" nominal) where higher loads are expected.

SF-20 Wall Thickness & Gauges (by OD)
| 1-3/8" OD (1.315") | .080" wall — 14 ga |
| 1-5/8" OD (1.660") | .085" wall — 13 ga |
| 1-7/8" OD (1.900") | .090" wall — 13 ga |
| 2-3/8" OD (2.375") | .095" wall — 13 ga |
| 2-7/8" OD (2.875") | .110" wall — 11 ga |
Installation Notes
Set terminals, then line posts at layout spacing. Use swedged top-rail lengths to create continuous rails, or join non-swedged rail with sleeves. Square, plumb, and brace before stretching fabric to tension bars; secure with the correct bands, rail ends, and caps for your ODs.
Buying Guide
- When to choose SF-20 — Taller fences, wind exposure, privacy slats, or higher traffic loading than .065" can comfortably handle.
- Pick diameters by load — Larger ODs at terminals/gates manage stretch and hardware loads; lighter ODs suit top rail.
- Swedged vs. sleeves — Swedged top rail speeds install and reduces parts; sleeves are great for repairs or non-swedged rail.
Frequently Asked Questions
- How does SF-20 compare to .065" residential?
- SF-20 uses a heavier wall for added stiffness and durability. It’s a common upgrade for taller fences, windy sites, or when adding slats/signage.
- Is swedged top rail available?
- Yes—select swedged lengths for continuous runs without sleeves. Non-swedged rail can be joined with sleeves.
- Can I weld SF-20 for gate frames?
- Yes—SF-20 tubing is commonly used for welded and fitted residential/commercial gate frames. Match OD to your hinge/latch hardware.
Comparison
- .065" Residential Framework — Lighter 16-ga tubing for standard home fences.
- SF-20 (this product) — Heavier wall for added rigidity; a solid choice for taller runs, wind exposure, or slatted fabric.
- SF-40 — Premium commercial/industrial framework with thicker walls for the highest loads and traffic.

Best poles on the market
I could not find heavier gauge pipe local and by some twist of luck I landed on the signet site. Great experience, I even emailed after the order and added more and they made that process easy too. A++
