Galvanized fence pipe is circular structural welded tube made from carbon steel substrate. It is specially used for fence posts, guardrail posts, cross rails and fence corner posts. Both inner and outer surfaces are zinc‑coated for excellent anti‑corrosion performance. Posts buried in soil can remain rust‑free for many years.
Glory Steel is a professional manufacturer & supplier of galvanized fence pipes. We supply hot‑dip galvanized and pre‑galvanized fence pipes, compatible with most zinc‑steel guardrail systems. International standards are complied. Custom cut‑to‑length and punching services are available.

Key Advantages
- Long‑term anti‑corrosion: Hot‑dip galvanizing delivers thick zinc coating with firm alloy layer. Service life over 20 years under normal outdoor conditions.
- High structural strength: Carbon‑steel base provides good mechanical performance, bending resistance and impact resistance for stable support.
- Maintenance‑free: Silvery metallic zinc surface. No additional powder coating or anti‑rust paint required; self‑cleaning by rainwater.
- Universal standard dimensions: NPS‑compliant outer diameter, compatible with standard tees, elbows, couplings for fast installation.
Applications
- Farm & livestock fencing: Posts for grassland mesh, farm enclosures and livestock pens.
- Municipal road guardrails: Posts for temporary road barriers, tree support stakes and highway fence brackets.
- Industrial & commercial fencing: Cross rails for factory partitions, sliding gate rails, side posts for automatic gates.
- Public & school fencing: Posts for airport, prison perimeter fences and powder‑coated basketball court enclosures.

Production & Inspection
All galvanized fence pipes undergo in‑house inspection for appearance, dimensional tolerance and zinc‑coating thickness. Zero missed‑galvanizing or peeling defects. Third‑party inspection by SGS / BV is acceptable. Services include square cut ends, deburring and protective pipe caps.
1. Production steps
Black tube inspection → Degreasing → Rinsing → Pickling → Flux treatment → Drying → Hot‑dip galvanizing → Cooling → Passivation → Full inspection → Bundling & labeling.

FAQ
Q: Can you provide material certificates?
A: MTC (EN 10204 3.1/3.2) is supplied with goods. Third‑party inspection by SGS, BV is available.
Q: What is the standard length for fence pipe?
A: Standard length is 6m (20ft). Custom length from 1‑12m is acceptable.
Q: Will galvanizing be damaged after welding?
A: Zinc coating will burn off at weld seams. We recommend repairing welds with zinc‑rich paint to restore corrosion resistance.
